Waste PVC Pulveriser Grinder  Application Areas:

This machine is used where waste PVC processing is the input but a saleable or specification-grade powder product is the output. Primary application areas include:

• White and light-coloured PVC compound production: recycled PVC pipe and profile offcuts ground to 40–60 mesh for reintroduction into white PVC formulations, where iron contamination from blower impeller wear would cause visible discolouration
• PVC powder for resale: recycling processors supplying ground PVC powder to compounders or masterbatch producers, where powder purity and consistent particle size are commercial quality requirements
• Food-contact and medical PVC applications: facilities producing PVC film, sheet, or profiles for food-contact or pharmaceutical packaging, where raw material purity traceability is required throughout the process

For high-volume waste PVC processing where powder purity is not a constraint, see the standard PNMP PVC pulverizer for a cost-optimised configuration.

Waste PVC Pulveriser Grinder  Description:

The PNMP waste PVC pulveriser grinder is configured for PVC powder production where output powder purity is a priority. The defining hardware feature of this variant is the top-mounted air blower: the blower sits above the machine and handles pneumatic conveying of ground powder through a separate circuit — the powder stream never passes through the blower impeller. In standard bottom-mounted blower configurations, powder contact with the rotating impeller causes minor particle attrition and, over time, trace metal contamination from impeller wear. The top-mounted design eliminates this contact point entirely.

This makes the machine the preferred configuration for producing PVC powder destined for applications with tighter purity requirements: white and light-coloured PVC compound, PVC for food-contact packaging film, and medical-grade PVC formulations. For general-purpose waste PVC recycling where powder purity is not a primary concern, the standard PNMP configuration is adequate. Output range: 15–100 mesh at 100–900 kg/h across four models.

Working Principle of PVC Pulveriser:

Waste PVC Pulveriser Grinder  Technical Features:

• Top-mounted air blower — powder conveying circuit is separated from the blower impeller; ground PVC powder never contacts the blower, eliminating a source of particle attrition and trace metal contamination in the powder stream.
• Compact footprint — top-mounted blower reduces the machine’s floor area compared to side-mounted blower configurations, an advantage in workshops where floor space is constrained.
• Adjustable output fineness (15–100 mesh) — blade gap adjusted via feeler gauge during operation; single machine covers the full range from coarse recycled compound filler to fine powder for film or medical applications.
• Closed-loop grinding — vibrating screen returns oversized particles to the disc automatically; consistent output fineness from variable-quality waste PVC input.
• Dual water-and-air cooling — stable processing temperature during continuous runs on heat-sensitive PVC grades.
• SKF bearings, Siemens motor — standard specification across PNMP-500 through PNMP-1000.

Waste PVC Pulveriser Grinder Components:

Vibration Loader Feeds waste PVC granules or pre-crushed fragments into the grinding chamber at a metered rate. Consistent feed prevents peak disc loading and maintains stable output powder fineness across a production run.	PVC Pulverizer Disc Turbo-type disc with adjustable static and rotary blade gap. Output fineness tunable from 15 to 100 mesh without stopping the machine — covers the full range from recycled compound filler to purity-grade powder production in a single unit.
PVC Pulverizer Blade D2 or SKD-11 steel. For waste PVC input with mixed hardness grades, SKD-11 is recommended for its higher wear resistance. Replaceable through the front service door without dismantling the grinding chamber.	Conveying pipe : 304 stainless steel throughout, double-layer with water cooling. Combined with the top-mounted blower design, the stainless conveying system provides a contamination-controlled powder path from grinding disc to collection bin.
Vibrating Screen Real-time powder classification. On-spec particles discharge continuously; oversized particles return to the disc automatically. Screen mesh is interchangeable to adjust target output fineness between production runs.	Intelligent Control PLC panel manages feed rate, disc speed, and cooling. Fault detection halts the machine and displays an error code on overload or temperature exceedance — important for continuous powder production runs with minimal operator supervision.
Bags Type Dust Catcher Standard dust control option. Adequate for most single-unit installations in ventilated workshops processing clean or lightly contaminated waste PVC.	Pulse Dust Collecter(Optional) Recommended for enclosed workshops or higher-throughput configurations. Pulse-jet self-cleaning maintains stable airflow resistance without manual intervention during extended production runs.

Frequently Asked Questions

Why does the blower position affect powder purity?

In a conventional bottom or side-mounted blower configuration, ground PVC powder passes through the blower impeller as part of the pneumatic conveying circuit. The high-speed impeller contact causes minor secondary particle size reduction (attrition) and, over time, generates trace metal particles from impeller surface wear. For most general recycling applications this is not a problem. For white, light-coloured, food-contact, or medical PVC powder, even trace metal contamination causes visible defects or fails material specification. The top-mounted blower design routes the powder through a bypass circuit that avoids the impeller entirely, removing this contamination pathway.

What types of waste PVC can this machine process?

The machine handles rigid and semi-rigid waste PVC from low to moderate hardness: UPVC pipe offcuts, PVC profile trimmings, PVC board and sheet, injection-moulded rejects, PVC bottles, and PVC cards. Input material should be pre-crushed to 10–30 mm before entering the grinding chamber. Raw film or highly plasticised soft PVC (Shore A below 60) requires a different configuration — see the PVC film pulverizer for flexible material applications.

What powder specifications does this machine produce for resale or compound use?

Output fineness is 15–100 mesh (approximately 150–1,000 µm), adjusted by blade gap setting. For recycled PVC powder supplied to compounders, 40–60 mesh is the standard accepted specification. For PVC powder used in film extrusion or medical applications, 60–80 mesh is typically required. Bulk density of output powder depends on PVC grade and processing temperature; most rigid PVC grades produce powder in the 400–550 g/L bulk density range at 40–60 mesh.
