Suzhou, March 2026 — As global plastic recycling accelerates toward zero-waste objectives and intelligent manufacturing upgrades, Weshaw announces the comprehensive optimization of its proven PSM-650 Intelligent Pulverizer.
Rather than introducing a completely new model, Weshaw has refined and upgraded the existing PSM-650 platform, enhancing mechanical performance, system coordination, and operational stability to better serve modern recycling and fine powder production demands.
The optimized PSM-650 integrates high-speed precision pulverizing, intelligent conveying, and environmentally controlled closed-loop processing into a compact industrial solution. It is engineered for plastic recycling plants, engineering compound manufacturers, and advanced powder processing facilities seeking consistent, high-quality output.

Upgraded Core Components
- Precision-grade imported bearings
- International electrical control components
- High-performance sealing system
Smart Control System
- CS-650 intelligent monitoring system ensuring stable long-term operation
Intelligent Closed-Loop Auxiliary System
The optimized PSM-650 is equipped with a fully integrated airflow and dust management system:
- 5.5 kW suction blower
- 159 mm stainless steel conveying pipeline
- 800 L large-capacity storage silo (compatible with 1200 × 1200 × 3000 mm structure)
- 1.5 kW rotary airlock feeder (7 L feeding volume)
- Five bag-type dust collectors
This configuration creates a continuous, low-intervention production loop from feeding to storage, significantly reducing dust emission and secondary contamination risks while supporting unattended operation.
Three Strategic Optimization Advantages
1. Higher Stability Under High Load
With a 2900 rpm rotor and 60 precision blades, the upgraded PSM-650 maintains consistent 300–450 kg/h throughput even when processing high-filler or high-toughness recycled plastics.
2. Cleaner, Safer Production Environment
The multi-stage dust collection system and stainless-steel conveying design improve environmental compliance and workplace safety, aligning with stricter green manufacturing standards.
3. Modular Adaptability for Future Materials
The optimized platform includes reserved customization interfaces, allowing flexible screen replacement and blade configuration adjustments for bio-based plastics, high-value recycled compounds, and specialty fine powder applications.
Proven Platform, Refined for the Future
The PSM-650 has already been widely deployed across recycling facilities in the Yangtze River Delta region. Through systematic engineering upgrades and component optimization, Weshaw strengthens the machine’s long-term operational reliability and processing precision.
Service Commitment:
- 18-month full-machine warranty
- Lifetime fast-response wear parts support
- Material testing and process optimization services
By enhancing an already proven system, Weshaw reinforces the PSM-650 Intelligent Pulverizer as a reliable, high-efficiency solution for precision powder production within today’s evolving circular economy.
