Waste Plastic SPC PVC Floor Pulverizer Recycling Machine Application Areas:

This machine is configured specifically for high-volume recycling of composite plastic flooring: SPC (stone plastic composite), WPC (wood plastic composite), LVT (luxury vinyl tile), and homogeneous PVC floor. These materials share a common processing challenge — their high calcium carbonate or mineral filler content (typically 50–70% by weight in SPC) generates significantly higher abrasive wear on grinding components than pure PVC, and the dense, rigid composite structure requires higher disc torque than standard PVC pipe or profile.

Two deployment scenarios are most common. The first is in-line scrap recycling on SPC production lines: trim waste and rejected boards from the cutting stage are conveyed directly to the pulveriser and ground to 60–80 mesh for reintroduction into the SPC base layer compound in the same shift. The second is post-collection floor recycling: facilities receiving mixed LVT, SPC, and WPC waste from installation contractors or distributors process pre-crushed floor chips into powder for resale to compounders or reuse in lower-specification PVC construction materials.

Waste Plastic SPC PVC Floor Pulverizer Recycling Machine Description：

The PNMP SPC floor pulverizer uses a turbo-blade disc with independently adjustable static and rotary blade gap, producing powder from 15 to 100 mesh at 400–900 kg/h on a single PNMP-1000 unit. For facilities requiring higher throughput, two units running in parallel with a shared belt conveyor infeed and common pulse dust collector achieve 1,200 kg/h and above.

The defining hardware difference from standard PNMP configurations is the belt conveyor with magnetic roller feeder: as floor chips travel along the belt, a magnetic head pulley captures ferrous particles — metal clips, staples, and fixing hardware that commonly contaminate post-installation floor waste — before they reach the grinding disc. This protects the turbo-blade from impact damage and prevents iron contamination in the output powder.

For SPC and WPC materials, SKD-11 blades are the standard specification — the high calcium carbonate filler content in these composites is significantly more abrasive than pure PVC, and SKD-11’s higher hardness (HRC 60+) extends blade service life under these conditions.

Waste Plastic SPC PVC Floor Pulverizer Recycling Machine Technical Features:

• Belt conveyor with magnetic roller — standard on this configuration; removes ferrous tramp metal from composite floor chip stream before grinding, protecting the disc and maintaining powder purity for reintroduction into floor compound.
• SKD-11 blade specification for SPC/WPC — high-chromium steel (HRC 60+) handles the abrasive calcium carbonate filler content in composite floor materials; longer service intervals than D2 under equivalent SPC processing loads.
• Up to 1,200 kg/h in parallel configuration — single PNMP-1000 delivers 400–900 kg/h; two units sharing a common belt infeed and pulse dust collector system reach 1,200 kg/h and above without proportionally scaling floor space.
• Adjustable output fineness (15–100 mesh) — 60–80 mesh for SPC base layer reintroduction; 40–60 mesh for general compound or external sale; adjusted via feeler gauge during operation.
• Dual water-and-air cooling — continuous operation on high-CaCO₃ floor materials generates more friction heat than standard PVC; dual cooling maintains stable disc temperature throughout extended production runs.
• SKF bearings, Siemens motor — standard specification across PNMP-500 through PNMP-1000.

Waste Plastic SPC PVC Floor Pulverizer Recycling Machine Components:

Conveyor belt feeding Belt conveyor with magnetic head roller captures ferrous contaminants — metal clips, staples, and fixing hardware from post-installation floor waste — before the chip stream enters the grinding chamber. Standard on this SPC/WPC floor configuration; protects the disc and maintains output powder purity.	PVC Pulverizer Disc Turbo-blade disc with adjustable gap handles SPC, WPC, and LVT composite floor structures directly. SKD-11 blade specification recommended over D2 for the higher abrasive load from calcium carbonate-filled floor materials.
PVC Pulverizer Blade SKD-11 high-chromium steel standard for SPC floor recycling. Calcium carbonate filler (50–70% by weight in SPC) accelerates wear on standard D2 blades; SKD-11 provides measurably longer intervals between replacements. Accessible through the front service door.	Conveying pipe : 304 stainless steel, double-layer water-cooled. Prevents rust contamination in the powder stream — important when recycled SPC powder is reintroduced into white or light-coloured floor base layer compound.
Vibrating Screen Real-time classification returns oversized floor chip fragments to the disc automatically. Interchangeable mesh for 40–60 mesh (general recycled compound) or 60–80 mesh (SPC base layer reintroduction).	Intelligent Control PLC panel with fault detection. For SPC production line configurations where the pulveriser runs continuously, automated fault halting prevents undetected powder quality drift from reaching the compound mix.
Bags Type Dust Catcher Entry-level option for lower-throughput installations. Calcium carbonate fines from SPC floor grinding generate higher dust load than pure PVC — pulse dust collector is the recommended upgrade for continuous floor recycling.	Pulse Dust Collecter(Optional) Recommended for SPC and WPC floor recycling. Calcium carbonate fines require higher filtration efficiency than standard PVC dust; pulse-jet self-cleaning maintains stable airflow resistance across extended production runs.

Frequently Asked Questions

Why is SKD-11 recommended over D2 blades for SPC floor recycling?

SPC flooring contains 50–70% calcium carbonate filler by weight, which is significantly more abrasive than the PVC resin component. Under continuous SPC grinding, D2 steel blades wear faster and require more frequent replacement. SKD-11 high-chromium steel (Rockwell hardness HRC 60+) offers greater resistance to abrasive wear under these conditions, extending the interval between blade replacements and reducing operating cost per tonne of processed material. For pure PVC floor types (homogeneous vinyl, LVT with low filler content), D2 is adequate.

What is the purpose of the magnetic roller on the belt conveyor?

Post-installation floor waste commonly contains ferrous contaminants — metal installation clips, staples, nails, and fixing brackets mixed in with the floor offcuts. If these reach the grinding disc, they cause impact damage to the blade edges and introduce metal particles into the output powder. The magnetic head pulley on the belt conveyor captures these ferrous fragments as the chip stream passes over it, before the material drops into the grinding chamber inlet. This is the primary reason this configuration uses a belt conveyor rather than a vibrating loader — the magnetic roller function is the key hardware difference.

How does this machine differ from the PNMP PVC foam sheet and floor pulverizer?

Both use the PNMP turbo-blade disc platform. The distinction is configuration and target application: the PVC foam sheet and floor pulverizer uses a vibrating loader and covers both foam board and floor materials across the full 100–900 kg/h range. This machine uses a belt conveyor with magnetic roller, is configured specifically for composite floor waste (SPC, WPC, LVT) with higher mineral filler content, and is the standard choice when post-installation floor waste with potential metal contamination is the primary input material.
