Plastic Pulverizer Machine

Plastic Pulverizer Machine

Key Features of the Plastic Pulverizer

High-Efficiency Grinding Technology

• Turbo/PNMF disc-type pulverizer with balanced rotor delivers high throughput and fine, uniform powder distribution.
• Optimized grinding gap and hardened alloy discs ensure sharp cutting action, reduced heat build-up, and extended tool life.
• Adjustable particle size control (typ. 20–80 mesh) meets diverse downstream requirements for extrusion, injection, and roto-molding.

Materials and Build Quality

• Wear-resistant alloy steel or tungsten-carbide coated discs for abrasive resins and filled compounds (CaCO3, talc).
• Heavy-duty bearing housing with forced air cooling and vibration isolation for stable long-term operation.
• Stainless steel contact parts optional; smooth internal surfaces minimize contamination and facilitate cleaning.

Process Engineering and Dust Control

• Closed-loop pneumatic conveying with cyclone separator and dust collector for low-loss recovery and clean environment.
• Integrated temperature monitoring and automatic feed regulation prevent material degradation and agglomeration.
• Quick-change sieve and tool access reduce downtime and speed up product grade changes.

Applications and Industries

Building and Construction

• PVC pipe and profile regrind to powder for reprocessing, WPC/SPC flooring base, conduit and window profile recycling.

Furniture and Interior

• Edge banding and decorative film reprocessing, ABS/PP furniture accessories powder preparation for compounding.

Automotive and Electrical

• ABS/PC trim and interior part recycling, PP/PA powder for under-hood components and cable accessory manufacturing.

Packaging and Consumer Goods

• PE/PP bottle and cap recycling to powder, masterbatch pre-pulverization for uniform dispersion in extrusion and injection.

Rotational Molding and Compounding

• PE rotomolding powder production with controlled flow index and narrow particle size distribution.
• Pre-pulverized PVC dry blend for stable gelation and improved extrusion consistency.

Technical Specifications

Performance and Capacity

• Output capacity: typically 100–800 kg/h per machine depending on material, mesh size, and moisture.
• Particle size: adjustable 20–80 mesh; narrow PSD with uniform bulk density for downstream stability.
• Temperature control: air or water-assisted cooling to maintain resin properties and color.

Mechanical Configuration

• Disc diameter options: 300–800 mm; high-speed rotor with precision dynamic balance.
• Automatic feeder with frequency inverter ensures constant load and steady amperage.
• Cyclone separator, rotary airlock, and dust filter (bag or cartridge type) for efficient powder collection.
• Magnet trap and inline sieve optional to remove metal and oversize particles, protecting extruders.

Controls and Connectivity

• PLC + HMI touchscreen with recipe management, amp/temperature trending, and alarm history.
• Interlocks for bearing overheat, motor overload, and negative pressure loss to ensure safe operation.
• Connectivity via Modbus-TCP/Ethernet for SCADA/MES integration and remote diagnostics.

Energy and Utilities

• Installed power: 22–90 kW per line depending on disc size and target mesh.
• Specific energy optimized via VFD control and intelligent feed; low kWh per ton for cost-effective pulverizing.
• Airflow: engineered ducts and silencers reduce noise and maintain stable negative pressure.

Note: Parameters vary with resin type, filler content, and target mesh. Custom configurations available on request.

Customer Case
