Grinding Disc Plastic Pulverizer

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.

● New-generation grinding disc delivers better quality, stronger wear resistance, and twice the service life of an ordinary disc.

● High-speed professional bearings paired with a single drive motor ensure efficient grinding and pulverizing, eliminating the cost and complexity of multi-motor systems.

● Easy maintenance — the machine can be cleaned and serviced simply by opening the access door.

● Fully sealed pulverizing process with zero dust leakage, suitable for clean-room and shop-floor production.

● Fully automatic operation: automatic feeding, automatic discharging, and automatic sorting reduce labour and keep production continuous.

● Easy grinding-gap adjustment using a feeler gauge and adjusting bolts to fine-tune output for different material hardness and particle size requirements.

● Water + Air dual cooling prevents overheating of the main shaft and bearings, supporting long continuous duty cycles.

● 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.

● Highly configurable: modular options are available to match customer budget and processing requirements, from small workshops to large production lines.

Specifications for the three main PPMF series models. Customised configurations are available on request.

● Pulverizing and recycling of PE / PP / EVA thermoplastic scrap, injection-moulded parts and blow-moulded parts;

● Fine grinding of waste plastic films, woven bags, pipes and sheets;

● Raw-material fine grinding for plastic compounding, filler masterbatch and colour masterbatch production;

● Recycling of rotational-moulding flash and trial-mould material;

● On-site closed-loop pulverizing in injection, blow-moulding and extrusion production lines.

● Converter / vacuum loader / screw conveyor — for automatic and metered feeding;

● Magnetic grille / metal separator — to remove metallic contaminants and protect the disc and blades;

● Chiller — stabilises cooling-water temperature and improves water-cooling efficiency;

● Pulse-jet dust collector — captures fugitive dust and keeps the workshop clean;

● Weighing and packaging machine — for automatic metering and bagging of finished powder.

● One-year warranty on the complete machine; original factory warranty on key electrical and mechanical components;

● On-site installation, commissioning, operator training and process optimisation guidance;

● 7 × 24 remote technical support, with critical spare parts shipped within 48 hours;

● Complete turnkey pulverizing line design tailored to your material, throughput and site conditions.
