Custom Plastic Pulverizer Machine Grinding Disc Manufacturer Industrial Plastic Grinding Mill Supplier Factory Direct

Product Overview

The PPMF Series Grinding Disc Plastic Pulverizer accepts disc diameters from 400 to 800 mm and is purpose-built for high-speed, precision pulverizing of PE, PP, EVA and other medium-hard, impact-resistant and brittle plastics. The main shaft is machined on a high-speed precision grinder, the inner chamber is lined with wear-resistant liners, and the rotating material is fed vertically through the centre of a fixed grinding disc to meet a concentric high-speed rotating disc. Centrifugal force continuously carries material through the grinding zone, and the resulting powder is collected by an integrated blower and cyclone separation system for a continuous, dust-free process.

The standard machine is built from a drive motor, a disc-type grinding assembly, an inlet blower, a vibrating sieve and a dust removal system. Depending on the application, the PPMF series can be supplied as an integrated grinding-disc configuration or as separate grinding sections, and can be combined with vacuum loaders, screw conveyors, metal separators, magnetic grilles, chillers, pulse-jet dust collectors, and weighing/packaging machines to build a complete pulverizing line.

Four Core Advantages

✓ Automation

Fully automatic feeding, discharging and sorting in one integrated workflow.

✓ Higher Efficiency

A single drive motor delivers high-efficiency grinding and pulverizing, dramatically cutting cycle time.

✓ Cost Saving

Wear-resistant grinding disc lasts 2× longer than ordinary discs, lowering long-term operating cost.

✓ Smart Integration

Connects seamlessly with vacuum loaders, magnetic separation, dust collection and weighing / packaging for a complete smart line.

Performance Features

FEATURE New-generation grinding disc delivers better quality, stronger wear resistance, and twice the service life of an ordinary disc.
FEATURE High-speed professional bearings paired with a single drive motor ensure efficient grinding and pulverizing, eliminating the cost and complexity of multi-motor systems.
FEATURE Easy maintenance — the machine can be cleaned and serviced simply by opening the access door.
FEATURE Fully sealed pulverizing process with zero dust leakage, suitable for clean-room and shop-floor production.
FEATURE Fully automatic operation: automatic feeding, automatic discharging, and automatic sorting reduce labour and keep production continuous.
FEATURE Easy grinding-gap adjustment using a feeler gauge and adjusting bolts to fine-tune output for different material hardness and particle size requirements.
FEATURE Water + Air dual cooling prevents overheating of the main shaft and bearings, supporting long continuous duty cycles.
FEATURE Premium-brand components: SKF bearings, Siemens motor and other well-known brand parts ensure stability, low failure rate and minimal downtime for spare-part replacement.
FEATURE Highly configurable: modular options are available to match customer budget and processing requirements, from small workshops to large production lines.

Frequently Asked Questions (FAQ)

Q1: What materials can the PPMF Series Plastic Pulverizer process?

The PPMF series is purpose-built for high-speed, precision pulverizing of PE, PP, EVA, and other medium-hard, impact-resistant, and brittle thermoplastics, as well as recycled scrap, films, and rotational-moulding materials.

Q2: How do I adjust the output powder mesh size?

The output fineness (ranging from 20 to 120 mesh) is easily adjusted by modifying the grinding gap between the discs using a standard feeler gauge and adjusting bolts according to your target material size.

Q3: How does the cooling system prevent heat degradation?

The machine uses a dual Water + Air cooling system. This effectively dissipates heat generated during high-speed grinding, preventing heat-sensitive plastics from melting or degrading during continuous operation.

Q4: What is the expected service life of the grinding discs?

Our new-generation grinding discs are manufactured from high-strength wear-resistant alloys, delivering up to twice the service life compared to conventional discs, significantly reducing long-term maintenance costs.

Q5: Is the pulverizing operation dust-free?

Yes, the PPMF pulverizer operates in a fully sealed environment integrated with a high-efficiency blower and cyclone separation system (with optional pulse-jet dust collection) to ensure zero dust leakage on the shop floor.
