The PNMP PVC chip recycling machine is designed to pulverise PVC chip — the uniform 3–10 mm granules produced by a granulator or crusher in the upstream stage of a PVC recycling line. Because chip size is consistent and flow characteristics are predictable, the vibrating loader can meter material into the grinding disc at a steady, controlled rate. This is the key operational difference from processing irregular scrap or whole pipe: a uniform feed reduces instantaneous disc loading, minimises blade wear rate, and produces powder with tighter particle size distribution than variable-geometry input materials.

Output is 15–100 mesh at 100–900 kg/h depending on model. The PNMP chip recycling machine is commonly positioned as the final processing stage after a PVC pipe crusher granulator or scrap granulator in a complete PVC recycling plant.

PVC Chip Recycling Machine PVC Pulverizer Machine Application Areas:

PVC chip as a feedstock arises in two main scenarios. The first is in-line recycling: PVC pipe, profile, or board manufacturers run production offcuts and rejected pieces through a granulator positioned adjacent to the extrusion line. The resulting chip is fed directly to the PNMP pulveriser for same-shift powder recovery and reintroduction into the compound. The second is centralised recycling operations: facilities receiving sorted PVC pipe and profile scrap from collection networks use a primary granulator to standardise the input geometry before pulverising — a two-stage approach that protects the more expensive pulveriser disc from the shock loading that irregular scrap creates.

In both cases, chip as input material gives the pulveriser operator the most predictable and controllable processing conditions in a PVC powder production line.

PVC Chip Recycling Machine PVC Pulverizer Machine Description：

This PNMP PVC Plastic mill is chiefly designed to grind PVC. The pulverizer uses turbo type blade. The static blade and rotary blade could be adjusted, thus you can get different size of PVC powder with one grinder. High output, low energy consumption and long lifespan attract many customers around the world. It can be used for PVC plastic from PVC pipe/profile/soft sheet/bottle/card from low to moderate hardness PVC.
The output of our PNMP pulverizer can reach 100-900kg/h (15-100mesh).

PVC Chip Recycling Machine PVC Pulverizer Machine Technical Features:

• Optimised for uniform chip input (3–10 mm) — consistent granule size from an upstream granulator enables steady vibrating loader feed rate, reducing peak disc loading and extending blade service intervals compared to direct scrap processing.
• Adjustable output fineness (15–100 mesh) — blade gap tunable via feeler gauge during operation without stopping the machine. For chip recycling lines producing powder for PVC pipe compound, 40–60 mesh is the standard target.
• Closed-loop classification — vibrating screen returns oversized particles to the disc automatically; on-spec powder discharges continuously without manual intervention.
• Sealed milling chamber — no dust leakage during operation; entire powder stream conveyed pneumatically to the collection system.
• Dual water-and-air cooling — maintains stable processing temperature across continuous single- or multi-shift operation.
• SKF bearings, Siemens motor — standard across PNMP-500 through PNMP-1000; reduces unplanned downtime in production line environments where the pulveriser is a critical path machine.

PVC Chip Recycling Machine PVC Pulverizer Machine Components:

Vibration Loader Meters uniform PVC chip into the grinding chamber at a consistent rate. With granulator-output chip (3–10 mm), vibration frequency can be set to a stable operating point and left unchanged across a production run — unlike irregular scrap which requires constant feed rate adjustment.	PVC Pulverizer Disc Turbo-type disc with adjustable blade gap. For chip recycling applications, the consistent particle hardness and size of PVC chip allows the disc gap to be set once and maintained across extended runs with minimal drift in output powder fineness.
PVC Pulverizer Blade D2 or SKD-11 steel. For standard rigid UPVC chip, D2 is the typical specification. Uniform chip input reduces the peak impact loads that shorten blade life in irregular scrap processing, extending intervals between blade replacements.	Conveying pipe : 304 stainless steel, double-layer water-cooled. Prevents rust contamination in the powder stream — important for recycled PVC chip powder reintroduced into pipe or profile extrusion compounds.
Vibrating Screen Real-time classification with automatic return of oversize particles. For chip recycling, the narrow input particle size distribution means less recirculating load compared to processing irregular scrap — higher effective throughput at the same motor power.	Intelligent Control PLC panel with fault detection and error code display. In a production line configuration where the pulveriser runs continuously, automated fault halting protects the machine and prevents undetected powder quality drift.
Bags Type Dust Catcher Standard dust control for single-unit chip recycling installations. Adequate for most workshop environments processing clean or lightly contaminated PVC chip.	Pulse Dust Collecter(Optional) Recommended for chip recycling lines running two or three shifts continuously, or where chip surface contamination generates higher dust load during grinding.

Frequently Asked Questions

What is PVC chip, and why is it the preferred input form for a pulveriser?

PVC chip refers to the uniform granules (typically 3–10 mm) produced when a granulator or crusher reduces PVC pipe, profile, or board into a standardised particle size. Compared to irregular scrap fragments or whole sections, chip has consistent bulk density, predictable flow characteristics, and a narrow size range. This allows the vibrating feeder to meter material at a stable, constant rate — resulting in more even disc loading, lower peak blade stress, and tighter powder particle size distribution in the output. Most PVC recycling lines include a granulator upstream of the pulveriser specifically to produce chip as an intermediate product.

What mesh size is standard for PVC chip powder used in pipe or profile extrusion?

For reintroduction into rigid PVC pipe compound, 40–60 mesh is the most common specification. At this fineness, recycled PVC powder disperses evenly in a high-speed mixer with stabilisers and lubricants without requiring additional milling. Profile extrusion compounds typically accept the same range. For applications with tighter appearance requirements (clear or light-coloured profiles), 60–80 mesh may be specified to improve surface finish of the extruded product.

How does this machine fit into a complete PVC recycling line?

In a typical two-stage PVC recycling line, a PVC pipe crusher granulator reduces incoming pipe sections or profile offcuts to chip (3–10 mm) in the first stage. The PNMP chip recycling machine then grinds that chip to powder (15–100 mesh) in the second stage. The powder is discharged to a collection bin or directly to a mixer for compound preparation. For complete line configurations including optional washing, metal detection, and automated powder packing, see the PVC Recycling Plant overview.
