Vertical disc grinding machine PNMF series

workpieceverticalPLC-controlled

Application Areas:
PNMF stainless-steel disc-type pulverizer is designed for continuous powder processing of thermoplastics including PE, HDPE, LDPE, PVC, PP, PS, ABS, EVA, PET and nylons. Suitable for masterbatch production, compounding and recycling workflows requiring 20–120 mesh output.

Description:
The PNMF series uses a vertically fixed grinding disc and a concentric high-speed rotating disc to achieve efficient centrifugal grinding. The machine body and processing cavity are manufactured in 304 stainless steel to prevent iron contamination. Powder is evacuated by blower and collected via cyclone. Disc diameters are available from 300 to 800 mm, with modular blade configurations (one-piece or segmented) to match material characteristics.

Components:

• Vibratory feeder: ensures even feeding and includes strong magnetism to capture metal contaminants.
• 304 stainless-steel pulverizer cavity: prevents iron filings and preserves powder purity.
• Integral pulverizer blades: high hardness and large cutting force; blades can be customized per material.
• Segmented blades: allow multiple resharpenings to reduce operating cost; split-blade options available on some models.
• Temperature control: enhanced cooling with spray nozzles, solenoid valves and thermostatic control for automatic material feeding switch.
• Vibrating screen: sized to grinding mesh for continuous production, automatic classification and easy screen replacement.
• Bags-type dust collector: compact footprint and cost-effective; pulse dust collector available for stricter emission requirements.
• Intelligent control system: simple operation with adjustable parameters for production optimization.

Optional Components:

• Magnetic filter frame / magnetic net
• Metal detector and separator
• Vacuum loader (plastic vacuum loader)
• Automatic screw feeder
• Industrial water chiller (air-cooled)
• Weighing & packing machine for plastic granules

Technical Features:

• New disc design for improved durability and wear resistance.
• High-speed professional bearings and single-drive motor for efficient, energy-saving grinding.
• Easy installation and maintenance with access door for cleaning.
• Sealed milling process to prevent dust leakage.
• Fully automatic operation: automatic feeding, discharging and sorting.
• Grinding gap adjustable via feeler gauge and bolts for precise fineness control.
• Combined water and forced-air cooling to protect bearings and components.
• Uses recognized-brand components (e.g., SKF bearings, Siemens motors) for extended service life.
• Wide range of optional accessories for tailored production solutions.
