Precision Disc-Type Pulverizing
Plastic Pulverizer & Grinding System for High-Quality Plastic Powder
Turn plastic scrap and flakes into consistent plastic powder with a precision disc-type pulverizer (micronizer). Designed for plastic grinding in recycling and compounding — stable output, tight particle size control, and easy maintenance to maximize uptime.
Built for Performance
Why Choose Our Plastic Pulverizer for Grinding?
Precision-engineered disc-type pulverizer delivering consistent powder quality, energy efficiency, and maximum uptime.
Consistent Particle Distribution
Precision disc grinding paired with screening delivers stable plastic powder size control for compounding, extrusion, and downstream processing.
High Efficiency, Lower Energy
Optimized grinding chamber and airflow reduce specific energy while maintaining consistent plastic powder output across a wide throughput range.
Durable & Easy Maintenance
Wear-resistant components and adjustable gap; modular layout simplifies service and changeovers for maximum uptime.
Multi-Material Versatility
Engineered for a wide range of thermoplastics — PE, PP, PVC, PC, HDPE, PS, SBS, and foamed plastics — with cooling and screening strategies tailored to each resin type.
Closed-Loop Process
How Plastic Grinding Works: From Scrap to Powder
A closed-loop process for consistent plastic powder production with automatic recirculation of oversized particles.
Metered Feeding
Plastic scrap is metered into the grinding chamber at a controlled, consistent rate for stable processing.
Disc Pulverizing
High-shear disc milling with adjustable static and rotating blades delivers efficient particle size reduction under controlled temperature.
Air Conveying & Classification
Air conveys and classifies the milled powder, separating qualified particles from oversized material for recirculation.
Vibration Screening
Vibration screening ensures only powder meeting target mesh passes through. Oversized particles return to the grinding chamber automatically.

Frequently Asked Questions
A micronize grinding system produces ultra-fine plastic powder (80-500 mesh) using high-speed impact mills or air-classifying mills. It goes beyond standard pulverizers to create fine powders used in rotational molding, powder coatings, compounding masterbatch, and specialty applications requiring very fine particle sizes.
Our system processes PE, PP, PVC, PA (nylon), PET, and other thermoplastics. Materials must be pre-granulated to 3-5mm. The system includes a grinding mill, air classifier for size separation, and cyclone collection. Cryogenic assist or specialized cooling may be needed for soft polymers like LDPE or heat-sensitive resins.
Our system is highly adjustable. By configuring the blades and screen mesh, you can consistently achieve particle sizes from 30 to 120 mesh (approx. 125–600 microns), with a very tight particle size distribution ideal for demanding applications.
Models cover roughly 150–800 kg/h. Optimized airflow and cooling reduce specific energy consumption while keeping output stable.
Depends on material and load. Check gap and balance regularly; replace knives and screens as needed. The modular layout supports fast access and cleaning.
Absolutely. We specialize in tailoring solutions. The milling chamber, cooling system, powder collection, and dust control can all be customized to your specific material, target particle size, capacity requirements, and facility layout.
Yes. This system is widely used as a PVC pulverizer and plastic micronizer. By adjusting disc gap, blade configuration, airflow, and screen mesh, it can reliably produce plastic powder in the range of 30–120 mesh (approximately 125–600 microns).
