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.
Why Choose Our Plastic Pulverizer for Grinding?
Consistent Particle Distribution for Superior Product Quality
Precision disc grinding paired with screening delivers stable plastic powder size control for compounding, extrusion, and downstream processing.
High Efficiency, Lower Energy to Reduce Operating Costs
Optimized grinding chamber and airflow reduce specific energy while maintaining consistent plastic powder output across a wide throughput range.
Durable & Easy Maintenance for Maximum Uptime
Wear‑resistant components and adjustable gap; modular layout simplifies service and changeovers.
How Plastic Grinding Works: From Scrap to Powder
Process Overview
This plastic grinding system uses a closed-loop process for consistent plastic powder: Metered feeding → disc pulverizing under controlled shear → air conveying & classification → vibration screening → qualified powder collection with automatic recirculation.
Key Controls
- Adjustable static/rotary blades and gap for target size
- Air/water cooling combo to manage heat‑sensitive resins
- Dust extraction to reduce emissions and improve safety
- Balanced rotors and durable materials for uptime

Frequently Asked Questions
What materials does it support?
Common resins include PE, PVC, PC, HDPE, PS, SBS, and foamed grades. For heat‑sensitive or filled materials, cooling and screening strategies help maintain quality.
What particle sizes can I achieve?
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.
How do throughput and energy balance?
Models cover roughly 150–800 kg/h. Optimized airflow and cooling reduce specific energy consumption while keeping output stable.
What is the maintenance cycle?
Depends on material and load. Check gap and balance regularly, replace knives and screens as needed. The modular layout supports fast access and cleaning.
Do you provide custom configurations?
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.
Is this plastic pulverizer suitable for PVC grinding, and what mesh or micron size can be achieved?
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), depending on material properties and cooling configuration.
