PVC Foam Sheet Floor Pulveriser PVC Plastic Pulverizer Description:

The PNMF series is a centrifugal disc-type pulveriser for medium-hardness thermoplastics. For PVC foam sheet and plastic flooring applications, it handles two distinct material types without configuration changes:

PVC foam board and sheet (including Forex/Sintra, PVC crust foam board, and free foam sheet) feeds directly through the disc centre after primary size reduction to 20–50 mm pieces. Centrifugal force carries material through the grinding gap; output powder at 40–80 mesh is suitable as a filler component in new foam board extrusion or as a secondary filler in PVC compounds.

Plastic flooring (LVT, SPC, WPC, and homogeneous vinyl) can be processed as intact composite cross-sections — no layer separation required. Pre-crushed flooring chips (30–50 mm) feed consistently through the disc mechanism, producing mixed-composition powder at 40–80 mesh suitable for SPC base layer recycling or PVC construction material filler.

Five disc diameter options (PNMF-300 to PNMF-800) cover output from 30 to 600 kg/h. Full machine specifications, component details, and working principle are covered on the PNMF PVC Film Pulverizer page.

PVC Foam Sheet Floor Pulveriser PVC Plastic Pulverizer Components:

Vibratory Feeding Magnetic vibratory feeder captures metal fragments from pre-crushed foam board or flooring chips before they reach the grinding disc — particularly relevant for floor installation waste which may contain staples or metal fixing clips.	Pulverizer Disc Fixed disc water-cooled cavity + rotating disc atomised spray cooling. For SPC and WPC floor materials with high calcium carbonate filler content, continuous dual cooling prevents premature disc wear from abrasive grinding.
Whole Body Pulverizer Blade Standard configuration for PNMF-300 through PNMF-500. Customisable tooth geometry for foam board (lower hardness) or composite floor (higher abrasive content) applications.	Segment Pulverizer Blade Available for PNMF-600 and PNMF-800. Resharpenable 4–5 times before replacement — recommended for SPC/WPC floor processing where higher calcium carbonate content accelerates blade wear.
Temperature Control Thermostat-controlled solenoid valve pauses material feed if disc temperature exceeds set threshold. Prevents thermal degradation of PVC foam compound during extended production runs.	Vibrating Screen Interchangeable mesh for different target fineness. For foam board compound filler, 40–60 mesh is standard; for SPC line reintroduction, 60–80 mesh.
Bags Type Dust Catcher Standard option for foam board recycling. Pulse dust collector recommended for SPC/WPC floor recycling due to calcium carbonate fines.	Intelligent Control PLC panel with fault detection. Single interface for disc speed, feed rate, and cooling. See full component specifications on the PNMF product page.

PVC Foam Sheet Floor Pulveriser PVC Plastic Pulverizer Technical Features:

The PNMF series shares a common platform across all disc diameter models. Key features relevant to foam sheet and floor applications:

1. No agglomeration required for rigid foam or flooring input — unlike soft PVC film which must be agglomerated before pulverising, rigid PVC foam board and pre-crushed flooring chips feed directly through the disc centre without pre-treatment beyond size reduction.
2. Segment blades (PNMF-600/800) reduce operating cost for abrasive floor materials — resharpenable 4–5 times before replacement, offsetting the higher blade wear rate from calcium carbonate-filled SPC and WPC floor composites.
3. 20–120 mesh output range — single machine covers foam board filler grade (40–60 mesh) and SPC line reintroduction grade (60–80 mesh) via disc gap adjustment.

Frequently Asked Questions

Does PVC foam board need to be agglomerated before pulverising, like PVC film?

No. Rigid PVC foam board (including crust foam and free foam sheet) can be fed directly after primary size reduction to 20–50 mm pieces — no agglomeration step is required. Agglomeration is only necessary for flexible, lightweight film material that cannot feed consistently into the disc inlet by gravity. Pre-crushed foam board granules have sufficient bulk density and rigidity to feed through the vibratory feeder without bridging or wrapping.

What mesh size should I target for SPC floor scrap reintroduced into production?

SPC floor production lines typically accept recycled powder at 60–80 mesh for reintroduction into the base layer compound. At this fineness, the recycled powder blends evenly with virgin PVC and calcium carbonate in the high-speed mixer. For external sale to compounders or use in less-critical applications (PVC construction sheet, pipe), 40–60 mesh is the common accepted specification.

How does the PNMF differ from the PNMP for foam sheet and floor applications?

The PNMP (turbo-blade disc) is designed for rigid, higher-hardness PVC materials such as pipe, profiles, and hard sheet at 100–900 kg/h. The PNMF (centrifugal flat disc) operates at lower throughput (30–600 kg/h) and is better suited to medium-hardness materials including foam board and composite flooring, where the centrifugal disc mechanism produces a more consistent fine powder distribution for filler-grade applications. For high-volume SPC floor recycling requiring throughput above 600 kg/h, the PNMP foam sheet and floor pulverizer is the alternative.
