Model 900 PVC Fine Powder Pulverizer: High-Capacity Grinding for Advanced PVC Recycling and Manufacturing

Modern PVC recycling and manufacturing operations require more than a conventional grinding machine. Large processors need dependable throughput, stable powder quality, controlled temperature, long component life, and a machine structure capable of continuous operation. The Model 900 PVC Fine Powder Pulverizer is designed for these demanding conditions. It combines a large grinding chamber, heavy-duty alloy grinding discs, variable-speed control, water cooling, stainless-steel conveying components, vibration management, and an integrated screening and dust-collection arrangement.

With a production range that can be configured from approximately 650 to 1,000 kg/h under the listed technical configuration, and higher production potential under optimized operating conditions, the Model 900 is intended for large PVC recycling plants, building-material manufacturers, compound producers, and export-oriented factories. Its principal function is to convert pre-sized PVC waste, production offcuts, profiles, pipes, flooring, cable sheathing, and other suitable materials into consistent fine powder for reuse in downstream processes.

Unlike smaller pulverizers that are primarily selected for pilot production or medium-volume recycling, this model is engineered for industrial-scale output. Its large disc geometry and high-power drive allow the machine to process substantial quantities of material while maintaining a controlled grinding environment. This makes it especially suitable for operations seeking to reduce unit processing costs and establish a closed-loop material recovery system.

The machine is also supported by the manufacturing capabilities of Changzhou Mao Yue Intelligent Equipment Co., Ltd., a source manufacturer with approximately 30 years of experience in plastic crushing and pulverizing equipment. The company operates several processing workshops, uses high-precision machining and dynamic-balancing equipment, and supplies pulverizing systems to customers in domestic and international markets.

1. A Flagship Solution for Large-Scale PVC Powder Production

PVC processing plants often face a difficult balance between output and powder quality. Increasing the feed rate can create excessive heat, irregular particle size, discoloration, agglomeration, or premature wear if the machine is not designed for heavy-duty work. The Model 900 addresses this challenge through a large grinding chamber and a high-power drive system that provide more processing capacity than smaller models in the same product family.

The machine is identified as a Model 900 unit, while the supplied technical table lists an approximately 800 mm disc diameter. Product configurations may vary according to the selected design, motor arrangement, and customer requirements. The available drive motor options are listed as 90 kW, 110 kW, and 132 kW. These options allow the purchaser to select a suitable balance between capacity, material characteristics, final fineness, and operating cost.

The machine can produce powder in a stated range of approximately 10 to 50 mesh. Actual fineness depends on the type and condition of the PVC feedstock, feed rate, rotor and disc settings, cooling conditions, and screening configuration. A suitable pretreatment system is important because the pulverizer is intended to refine already reduced material rather than replace the complete coarse-crushing stage.

For high-volume plants, the main benefit is not simply a high nameplate capacity. It is the ability to maintain stable production for long operating periods. A machine that delivers consistent powder quality with fewer stoppages can provide greater annual output than a smaller machine that requires frequent cleaning, adjustment, or disc replacement. The Model 900 is therefore positioned as a production machine for organizations that measure performance by daily tonnage, annual utilization, and long-term operating reliability.

In large PVC recycling programs, the pulverizer may serve as the central size-reduction unit after sorting, metal removal, coarse crushing, and preliminary separation. In PVC building-material production, it can process clean production scrap and selected recycled feedstock into a reusable powder for flooring, profiles, boards, pipes, and other products. In specialty-compound applications, it can support the preparation of powders with controlled fineness for later blending with stabilizers, impact modifiers, fillers, pigments, and other additives.

Model 900 PVC Fine Powder Pulverizer

2. Major Technical Features

2.1 Large Grinding Disc and Processing Chamber

The grinding disc is one of the most important components in a disc pulverizer. It determines the effective grinding area, the available shearing surface, and the machine’s ability to handle a large quantity of material in a short period. The Model 900 uses a large-diameter disc arrangement designed for high-volume PVC processing.

A larger grinding chamber gives material more opportunity to pass through the grinding zone while reducing the need to force excessive feed into a restricted space. This can support a more stable residence time and a more uniform powder-generation process. When paired with correct feeding and cooling, the larger chamber helps operators maintain production without imposing unnecessary stress on the drive motor.

The grinding geometry is designed to provide repeated mechanical action, including impact, friction, and shearing. PVC particles are progressively reduced as they move through the grinding zone. The resulting powder can then be conveyed toward screening and collection equipment. The exact particle-size distribution depends on the material, feed rate, disc condition, operating speed, and machine adjustment.

2.2 High-Power Drive Options

The Model 900 is offered with 90 kW, 110 kW, or 132 kW drive motor configurations. The higher-power versions are appropriate for demanding applications involving high throughput, thick PVC scrap, filled PVC, rigid profiles, pipe material, and other feedstocks that create greater grinding resistance.

The motor options also provide flexibility for different investment plans. A customer processing relatively clean and easily pulverized material may select a lower-power configuration. A large centralized recycling plant or a manufacturer working with high-filler or high-abrasion PVC may benefit from the 110 kW or 132 kW arrangement. Final motor selection should be based on a material test, target capacity, desired fineness, feed size, and expected operating schedule.

High drive power does not eliminate the need for correct feeding. Overfeeding can increase energy consumption and temperature, while underfeeding may reduce productivity and cause unstable operation. The best results are obtained when the feeding system, cooling system, screening system, and dust-collection system are balanced with the pulverizer’s motor capacity.

2.3 Inverter Speed Control

Variable-frequency inverter control allows the operator to adjust the machine speed according to the material and production target. This is a valuable advantage over fixed-speed equipment because PVC feedstocks can differ significantly in hardness, filler content, moisture, thickness, and thermal behavior.

Lower or controlled speed may be useful when processing material that is sensitive to heat or when a coarser powder is acceptable. Higher speed may be selected when the application demands greater grinding intensity and finer powder. Speed adjustment can also help operators manage startup, product changeover, and energy consumption.

Inverter control supports a more responsive production process. Instead of operating at one fixed condition regardless of the feedstock, the operator can adjust the machine to maintain a suitable relationship between feed rate, motor load, temperature, and powder fineness. This flexibility is especially useful in recycling plants that process several categories of PVC waste during the same working day.

2.4 High-Chromium Alloy Grinding Components

The listed knife and blade material is high-chromium alloy. This type of material is selected for its resistance to abrasion and its ability to maintain a useful working edge under demanding conditions. The grinding elements are exposed to repeated mechanical contact, and wear can accelerate when the feedstock contains mineral fillers, pigments, glass fiber, metal contamination, or other abrasive substances.

The flagship configuration is described as using super-heavy-duty, high-wear-resistant alloy grinding discs, with an expected service life of approximately 1,500 to 2,200 operating hours under suitable conditions. Actual service life varies according to feed composition, contamination level, operating load, cooling, cleaning, and maintenance practices. This range should therefore be treated as a reference rather than a universal guarantee.

Longer component life offers several operational benefits. It reduces the frequency of planned maintenance, limits production interruptions, helps preserve particle-size consistency, and lowers the labor requirement associated with disc replacement and adjustment. For a factory operating around the clock, these benefits can have a significant effect on annual operating cost.

2.5 Dual-Circuit Cooling and Temperature Management

Temperature control is essential in PVC pulverizing. Excessive heat can cause powder to soften, stick together, discolor, or degrade. It may also make cleaning more difficult and place additional stress on machine components. The Model 900 uses a water-cooling arrangement in which one connection serves as the inlet and another serves as the outlet.

The product information also describes a premium dual-circuit cooling design and intelligent temperature-control support. The purpose of this arrangement is to remove heat from the grinding area and help keep powder quality stable during high-load operation. Temperature management is particularly important when processing PVC with heat-sensitive additives, colored formulations, or strict appearance requirements.

A controlled cooling system helps reduce the risk of scorching, agglomeration, and unwanted color change. It also supports more consistent operation during long production runs. For best performance, the cooling-water supply should have adequate flow, suitable temperature, and appropriate filtration. Operators should also monitor the inlet and outlet conditions and follow the recommended maintenance schedule.

2.6 Stainless-Steel Material Conveying Pipe

The supplied specification lists all-stainless-steel pipe material and a pipe diameter of approximately 178 mm. Stainless-steel conveying components provide good resistance to corrosion and contamination, especially in systems where fine powder travels through an air stream.

A clean, smooth conveying path helps reduce powder retention and makes the system easier to inspect. It also supports hygienic and stable material transfer in applications where the powder must remain free from rust particles or contamination from the conveying line. The exact conveying arrangement should be designed according to the layout, airflow, powder properties, and distance between the pulverizer, classifier, screen, and collector.

2.7 Blower, Vibrating Screen, and Dust Collection

The standard specification includes a 15 kW blower and a vibrating screen with a 2.2 kW motor. The vibrating screen has a listed diameter of approximately 1,500 mm. These components form an important part of the complete production system because grinding alone does not guarantee a commercially useful final product.

The screen separates material according to the selected particle-size requirement. Oversize particles can be returned for further processing, while qualified powder proceeds to collection or packing. This arrangement helps improve product uniformity and enables the customer to establish a more controlled specification for downstream manufacturing.

The dust collector uses bags with a listed diameter of approximately 300 mm. Effective dust collection is essential for workplace cleanliness, product recovery, equipment protection, and compliance with environmental requirements. PVC powder should not be allowed to accumulate around motors, electrical cabinets, bearings, or hot surfaces. A correctly sized collection system can also help reduce material loss and improve the overall yield of the line.

2.8 Iron-Removal Feeding Arrangement

The listed feeding method includes iron-removal tie feeding. This indicates that the feeding section is designed to support the removal of ferrous contamination before it reaches the grinding chamber. Metal contamination is a serious risk in PVC recycling because it can damage blades and discs, increase downtime, create sparks, and reduce the quality of the final powder.

Although iron removal is valuable, incoming material should still be sorted and inspected before feeding. Operators should remove large metal objects, stones, excessive moisture, and unsuitable contaminants during the preparation stage. A layered contamination-control program provides better protection than relying on a single separator.

3. Advantages Over Smaller or Less Specialized Pulverizers

3.1 Higher Production Potential

The most direct advantage of the Model 900 is its suitability for higher-volume production. Smaller machines may be effective for workshops, laboratories, or moderate recycling operations, but they may require multiple units to meet the requirements of a large plant. A larger machine can reduce the number of parallel units, simplify material handling, and lower the space and labor required per ton of output.

The published material describes the Model 900 as a production champion with a substantial increase over the 850 model. The supplied specification table gives a capacity of approximately 650 to 1,000 kg/h, while the product description refers to optimized peak production reaching approximately 900 to 1,300 kg/h or more. Because actual output varies with feedstock and configuration, buyers should confirm the expected capacity through a material test and a detailed technical quotation.

Even when the machine is operated below its maximum potential, a large capacity reserve can be useful. It allows the plant to handle seasonal demand, future production growth, changes in material density, and variations in feed quality without immediately purchasing another pulverizer.

3.2 Better Suitability for High-Filler PVC

High-filler PVC can be more abrasive and more difficult to process than clean, unfilled material. Calcium carbonate, pigments, mineral modifiers, and other additives can accelerate wear on grinding surfaces. The heavy-duty alloy configuration of the Model 900 is intended to provide stronger resistance in these conditions than a light-duty machine.

For manufacturers of flooring, profiles, boards, pipes, and specialty compounds, the ability to process filled PVC is commercially important. It can enable the use of more production scrap and recycled material while maintaining a controlled powder specification. However, the feedstock should still be evaluated to determine whether additional wear protection, pre-cleaning, or a particular disc configuration is necessary.

3.3 More Stable Powder Quality

Large-scale manufacturers often require more than acceptable fineness. They need repeatable fineness, stable color, good flowability, and low levels of oversize material. The combination of controlled speed, large grinding geometry, cooling, screening, and dust collection supports a more consistent final powder.

Stable powder quality can improve downstream processing. In extrusion and calendering, more uniform powder may contribute to more consistent melting, product thickness, surface finish, and mechanical performance. In compound production, controlled particle size may improve blending and reduce variation between batches.

The pulverizer does not independently determine the quality of the finished PVC product. Feedstock sorting, formulation control, drying, blending, screening, and downstream processing remain important. Nevertheless, a stable pulverizing step provides a stronger foundation for the rest of the manufacturing process.

3.4 Reduced Thermal Damage

Some less specialized grinding systems allow temperature to rise rapidly under heavy load. PVC is especially sensitive to uncontrolled heat, and thermal damage may appear as discoloration, odor, sticking, or degradation. The Model 900’s water-cooling arrangement and intelligent temperature-control concept are intended to reduce this risk.

Temperature stability can be a competitive advantage when the customer processes white, light-colored, or precisely formulated PVC. It is also valuable when recycled powder must be mixed into a premium product without causing visible color variation or unstable processing behavior.

3.5 Lower Long-Term Interruption Risk

Industrial equipment should be evaluated by total cost of ownership rather than initial purchase price alone. Frequent disc replacement, bearing failure, overheating, unplanned cleaning, and unstable screening can reduce the effective production rate of a low-cost machine.

The Model 900 is designed around heavy-duty components, imported bearing options such as NSK bearings, a reinforced base, vibration damping, and serviceable line components. These features are intended to support longer continuous operation and reduce the frequency of avoidable downtime. A higher initial investment may therefore be justified when the machine is used intensively and the value of uninterrupted production is high.

4. Applications in PVC Recycling and Manufacturing

4.1 PVC Pipe and Profile Recycling

Discarded pipes, window profiles, door profiles, and construction trim are important sources of recyclable PVC. After sorting and coarse crushing, these materials can be pulverized into powder for use in recycled pipe, profile, extrusion, or injection-molding applications.

The Model 900 is suitable for centralized facilities that receive large quantities of post-industrial or post-consumer PVC. Its capacity can help processors handle continuous inbound material and supply powder to several downstream production lines. A suitable separation system is essential because construction waste may contain metal inserts, rubber seals, wood, dirt, and other unwanted materials.

4.2 PVC Flooring and Decorative Products

Flooring production may generate edge trim, rejected sheets, installation waste, and other PVC scrap. Recycling this material into powder can improve raw-material utilization and reduce disposal costs. Fine, consistent powder is valuable in applications where smooth surfaces, stable thickness, and reliable processing are important.

For flooring and decorative panels, operators typically pay close attention to color stability and contamination. The cooling system, dust collection, and material-separation stages should be managed carefully to preserve the appearance and performance of the recycled material.

4.3 Cable Sheathing and Industrial Offcuts

PVC cable sheathing and industrial offcuts can represent a significant volume of recyclable material. These materials may contain fillers, pigments, plasticizers, and reinforcement elements. Their processing behavior can vary substantially, so a controlled feed rate and suitable cooling are necessary.

The Model 900 can support the conversion of qualified cable-sheathing scrap into a reusable powder for compound production or other applications. Before processing, copper, aluminum, steel, and other non-PVC materials must be separated as thoroughly as possible. Metal removal protects the grinding components and improves powder purity.

4.4 High-Performance PVC Compounds

Specialty PVC powders may be used in formulations requiring flame resistance, impact resistance, weather resistance, chemical resistance, or heat stability. Such applications place higher demands on particle consistency and contamination control.

The pulverizer can support the preparation of powders for construction components, automotive interiors, electrical enclosures, cable products, and other engineered applications. The final performance depends on the complete formulation and manufacturing process, but uniform powder can improve the repeatability of blending and forming.

4.5 Export and OEM Production

International OEM manufacturers often require stable delivery, repeatable product quality, documentation, and compliance with safety and environmental expectations. A high-capacity pulverizer can help an export-oriented factory meet large orders without excessive dependence on multiple small machines.

The Model 900 may be integrated into a complete line that includes feeding, metal separation, coarse crushing, pulverizing, screening, dust collection, storage, and packing. Such integration can reduce manual handling and improve traceability. It can also help a manufacturer present a more consistent product specification to international customers.

5. Manufacturing Strengths Behind the Equipment

5.1 Long Experience in Plastic Size Reduction

Changzhou Mao Yue Intelligent Equipment Co., Ltd. has approximately three decades of experience in plastic crushing and pulverizing equipment. This experience is significant because plastic size reduction involves more than assembling a motor and a grinding chamber. Disc geometry, material selection, balancing, bearing arrangement, cooling, conveying, feeding, and dust control all affect the final performance.

Long-term involvement in the field allows the manufacturer to accumulate knowledge from different materials and operating environments. PVC, PE, polymers, masterbatch, powder-coating materials, and recycling feedstocks each present different requirements. This background supports the development of equipment configurations for both standard and customized applications.

5.2 Multiple Processing Workshops

The company operates six processing workshops, each averaging approximately 1,400 square meters. Multiple workshops can support different stages of fabrication, machining, welding, assembly, testing, and finishing. This type of production structure is useful for a manufacturer that supplies complete pulverizing systems as well as individual components.

A dedicated manufacturing environment can also improve process organization. Heavy base structures, grinding chambers, discs, piping, screens, and electrical assemblies require different production methods. Separating these activities helps the manufacturer manage workflow and maintain better control over large equipment orders.

5.3 High-Precision Machining

The factory is equipped with Taiwan-imported high-precision grinding machines built to German standards. Precision machining is particularly important for the grinding discs, shafts, bearing seats, and mating surfaces. Dimensional errors or poor surface quality can affect vibration, wear, noise, and powder consistency.

Accurate machining helps components fit correctly during assembly and supports more stable operation. It also makes replacement parts easier to install because the dimensions remain within controlled tolerances. For high-speed rotating equipment, precision is directly related to safety and service life.

5.4 Dynamic Balancing

The manufacturer uses German dynamic-balancing equipment. Dynamic balancing is essential for rotating assemblies because an unbalanced disc or rotor can create vibration, noise, bearing stress, and fatigue in the machine frame.

Effective balancing helps the pulverizer operate more smoothly at high speed. It may also reduce the transmission of vibration to surrounding equipment. Combined with a heavy-duty base and industrial vibration damping, balanced rotating parts can contribute to a more comfortable working environment and better protection of adjacent machinery.

5.5 Japanese Welding Systems

The factory uses Japanese welding systems to support the fabrication of frames, chambers, brackets, piping, and other structural components. Consistent welding quality is important because the machine must withstand continuous vibration and mechanical loading.

Well-executed welded structures help maintain alignment and reduce the risk of fatigue cracking. They also contribute to the overall appearance, maintainability, and service life of the equipment. Structural quality is sometimes overlooked when customers focus only on motor power, but it is essential for a large machine intended for continuous industrial use.

5.6 Quality and Certification

The company has obtained CE mechanical certification and ISO 9001 quality management system certification. CE-related compliance supports the design and supply of machinery for markets that require conformity with applicable European safety expectations. ISO 9001 indicates that the manufacturer operates a documented quality-management framework.

Certification does not replace proper installation, guarding, operator training, or site-specific risk assessment. However, it provides customers with additional confidence that the equipment is produced within an organized quality and safety system. Export customers should confirm the exact documentation package required for their destination country before placing an order.

6. Installation and Production Recommendations

The Model 900 should be installed on a stable foundation capable of supporting the machine, motor, conveying system, screen, and associated equipment. The foundation should be level and designed to limit vibration transmission. Adequate access must be provided around the grinding chamber, bearings, electrical cabinet, dust collector, and screen for inspection and maintenance.

The cooling-water system should be prepared before commissioning. Water flow, pressure, temperature, filtration, and drainage must comply with the supplier’s requirements. Poor water quality can cause scaling or blockage, while insufficient flow can reduce thermal-control performance.

Feedstock preparation is equally important. PVC should be sorted by type as far as practical, and large items should be reduced to a suitable feed size. Metal, stones, wood, rubber, excessive dust, and other foreign materials should be removed. Moisture should be controlled because wet material may affect conveying, screening, and powder quality.

During commissioning, the operator should begin at a conservative feed rate and gradually increase production while monitoring motor current, temperature, vibration, powder fineness, and dust-collection performance. The inverter should be adjusted only after the machine reaches stable operating conditions.

Routine maintenance should include inspection of grinding discs, blades, bearings, belts, fasteners, cooling lines, screen surfaces, blower components, filters, and electrical connections. Wear parts should be replaced or adjusted before their condition causes excessive energy consumption or poor powder quality.

7. Economic Value and Total Cost of Ownership

A high-capacity pulverizer represents a substantial investment, but its economic value should be calculated over the expected operating life. Important factors include annual throughput, operating hours, power consumption per ton, labor requirements, wear-part costs, downtime, material yield, and the selling value or internal value of the recycled powder.

The Model 900 is intended to reduce unit processing cost by combining large output with durable grinding components. If a plant replaces several small machines with one high-capacity unit, it may reduce duplicated feeding systems, operators, electrical connections, and maintenance points. The exact economic result depends on the plant layout and material characteristics.

Longer wear-part life can also improve financial performance. Disc replacement requires parts, labor, cleaning, alignment, and lost production time. A high-wear-resistant configuration may therefore provide savings beyond the price of the replacement component itself.

Energy efficiency should be evaluated by kilowatt-hours per ton rather than motor power alone. A larger motor consumes more power at full load, but a high-throughput machine may process more material per hour and achieve a lower energy cost per unit of output. Actual results should be confirmed through testing with the customer’s own PVC material.

8. Comparison with Conventional Competitor Equipment

Evaluation factor	Model 900 PVC Fine Powder Pulverizer	Typical smaller or basic pulverizer
Production positioning	Large-scale industrial and continuous production	Small to medium production or supplemental use
Drive options	90 kW, 110 kW, and 132 kW configurations	Often limited to one or a few lower-power options
Speed control	Inverter-based variable-speed operation	May use fixed-speed operation
Grinding components	High-chromium alloy and heavy-duty wear-resistant options	May use standard alloy components with shorter life under abrasive duty
Thermal management	Water cooling with temperature-control support	May use simpler or less controllable cooling
Material handling	Blower, stainless-steel pipe, vibrating screen, dust collector, and iron-removal feeding arrangement	May require separate equipment or more manual handling
Target applications	PVC recycling groups, major building-material plants, compound production, and export manufacturing	General recycling, small workshops, or lower-volume applications
Investment profile	Higher initial investment with a focus on long-term output and reduced downtime	Lower entry cost but potentially higher unit cost at large volumes

This comparison is a general guide rather than a substitute for a technical quotation. Competitor machines vary widely, and some may offer specialized features not included in a basic comparison. The principal advantage of the Model 900 is its integrated industrial positioning: high drive power, large grinding capacity, wear resistance, cooling, screening, conveying, and dust control are considered as parts of one production system.

9. Powder Quality and Downstream Benefits

The value of pulverized PVC depends on how consistently it can be reused. Powder that contains excessive oversize particles, scorched material, metal fragments, or agglomerates may be difficult to blend and may reduce the quality of the finished product.

The Model 900 is designed to produce powder with high fineness, controlled particle-size distribution, good flowability, and reduced risk of scorching or discoloration when correctly operated. Screening helps separate oversize material, while cooling helps manage the thermal conditions that influence powder appearance and behavior.

For extrusion lines, more consistent powder can support stable feeding and melting. For calendering, it may contribute to more uniform sheet formation. For flooring and decorative applications, controlled powder quality can help maintain surface appearance. For pipe and profile production, it can support more stable dimensions and mechanical performance when combined with a suitable formulation.

In recycled-material applications, powder consistency also improves blending with virgin resin and additives. Manufacturers can establish more predictable recipes and reduce variation between production batches. This can be especially important for customers supplying products under private-label or international OEM arrangements.

10. Safety, Environmental, and Workplace Considerations

Industrial PVC pulverizing should be managed with appropriate safety procedures. Operators should never open the grinding chamber while the machine is running or coasting. Electrical isolation, mechanical lockout, and verification of zero energy are necessary before maintenance.

Guards, emergency stops, protective devices, and warning labels should remain in place and functional. Personnel should receive training in feeding procedures, blockage removal, cooling-system operation, dust-collector maintenance, and wear-part replacement.

Dust control is important for both product recovery and workplace conditions. The dust collector should be inspected regularly, and filter bags should be cleaned or replaced according to the operating environment. The plant should also assess the characteristics of the processed powder and implement appropriate controls for combustible dust or other site-specific risks.

Noise management is another consideration. The product information states that the heavy-duty base and vibration-damping structure are designed to keep noise below approximately 90 dB under specified conditions. Actual sound levels depend on installation, surrounding equipment, material, speed, and building acoustics. Hearing protection and a site noise assessment should be used where necessary.

11. Why Select a Direct Manufacturer

Buying directly from a source manufacturer can provide advantages in technical communication, customization, spare-parts supply, and after-sales support. The customer can discuss material characteristics and production objectives with the equipment producer rather than relying solely on a general trading company.

Direct communication is especially useful when the application involves difficult feedstock, unusual particle-size requirements, special electrical standards, customized cooling, or integration with an existing line. The manufacturer can review the complete process and recommend a suitable combination of pulverizer, screen, blower, dust collector, and feeding equipment.

A direct manufacturer can also provide replacement discs, blades, bearings, belts, screens, filters, and other components according to the original machine design. This can reduce uncertainty during maintenance and help the customer restore production more quickly.

The company’s experience with more than 5,000 domestic and international enterprise partnerships demonstrates a broad customer base. Its focus on quality, service, innovation, and customized solutions supports the needs of customers who require more than a standard catalog machine.

12. Recommended Customer Profile

The Model 900 is most appropriate for customers with a substantial and consistent supply of PVC feedstock. This includes centralized recycling groups, PVC pipe and profile manufacturers, flooring producers, cable-material processors, compound manufacturers, and export-oriented factories.

It is particularly suitable when the customer requires high daily throughput, fine powder, stable color, long operating periods, controlled wear, and integration with automated conveying and collection systems. A company expecting to expand production may also select the Model 900 because its capacity reserve can support future growth.

For small workshops processing only a few hundred kilograms per day, a smaller pulverizer may be more economical. Equipment selection should always consider actual material volume, available floor space, electrical capacity, cooling-water supply, labor, and target return on investment.

13. Ordering and Technical Confirmation Checklist

Before ordering, customers should provide representative PVC samples or detailed information about the material. Important data includes PVC type, rigidity, filler content, moisture, contamination, initial size, required mesh size, color, plasticizer content, and expected hourly or daily production.

The customer should also confirm the preferred motor configuration, electrical voltage and frequency, cooling-water conditions, dust-collection requirements, screen specification, conveying distance, feeding arrangement, and packaging method. If the machine will be integrated into an existing line, the inlet and outlet elevations should be checked carefully.

A material test is strongly recommended for applications involving high filler, cable scrap, mixed post-consumer PVC, colored profiles, or strict powder specifications. Testing can help determine realistic capacity, power consumption, temperature behavior, and wear expectations.

Export customers should confirm local requirements concerning electrical components, guarding, documentation, noise, dust emissions, spare parts, and installation. The manufacturer can then prepare a configuration that is better aligned with the destination market and the customer’s production conditions.
