Fully Automatic PVC Granule Pulverizer System
A PLC-controlled plastic grinding machine engineered for PVC granules/pellets. Automated feeding and load-based control stabilize throughput while producing consistent powder for compounding and reuse.
- Granules-to-powder workflow with automated feeding and discharge
- Adjustable fineness via disc gap and screen mesh (typ. 20-120 mesh)
- Cyclone separation + vibrating screen with automatic regrind loop
- Options for cooling, noise control, and dust management
Automated Process Flow
Automatic Material Feeding
A vibratory feeder meters PVC granules from a hopper or silo into the mill at a controlled rate. Optional interfaces support level sensors and upstream conveying for continuous operation.
Intelligent, Self-Regulating Grinding
High-speed milling discs convert granules to powder. The PLC monitors motor load and adjusts feed rate to stabilize the grinding load and reduce overload events.
Automated Discharge & Sieving
Powder is pneumatically conveyed to cyclone separation and vibrating screening. The screen sets final mesh; oversize automatically returns for regrind, and qualified powder discharges to bagging or silo collection.
Material Condition Comparison
Before Grinding
Mixed PVC scrap and rubbery debris with irregular size and inconsistent feed behavior.
After Grinding
Uniform PVC powder suitable for compounding or reuse with controlled mesh output.
System Design Features
Unattended Operation
Automated feeding, grinding, screening, and discharge reduce operator touchpoints. Designed for stable, repeatable production with periodic checks rather than continuous supervision.
Load-Based Feed Control
PLC monitoring (motor load feedback) supports automatic feed-rate adjustment to maintain a stable grinding load, reducing nuisance trips and improving throughput stability.
Particle Size Consistency
Disc gap adjustment and downstream screening support repeatable mesh targets and tighter size distribution for compounding and in-house reuse.
Milling Disc Configuration
Wear-resistant discs and setup options can be matched to PVC formulation and target mesh. Control logic coordinates disc milling and feed rate for stable operation.
Separation and Regrind Loop
Cyclone separation and vibrating screening provide a closed-loop regrind path for oversize, supporting continuous production and controlled powder output.
Thermal and Noise Options
Optional cooling helps manage heat-sensitive PVC formulations; enclosure options support reduced airborne noise and cleaner installation in production environments.

Technical FAQ
Does "fully automatic" mean zero supervision is needed?
It means the machine handles the entire operational cycle—feeding, grinding, and discharging—without continuous operator involvement. Periodic supervision is recommended for monitoring raw material supply and general system checks, but it does not require a dedicated, full-time operator.
How does the system integrate with my existing production line?
Our system is designed for flexible integration. It can be fed from a main storage silo via pneumatic conveying, and the output can be directed to collection bins or another conveyor system. We can discuss your specific layout and provide a tailored integration plan.
What safety features are included for unattended operation?
The system includes multiple safety interlocks, such as automatic shutdown for motor overload, jam detection, and emergency stop buttons. The PLC controller provides real-time diagnostics to alert staff to any potential issues, ensuring safe and reliable operation.
What makes the milling discs "high-performance"?
Our high-performance discs are crafted from a superior, wear-resistant steel alloy and feature an optimized geometry with a higher number of teeth. This design allows for a more aggressive yet precise cut, resulting in finer particles and a longer service life compared to standard discs.
How fine can the powder be, and is the particle size adjustable?
Yes, the particle size is adjustable. By changing the gap between the rotating and fixed discs, and by using different screen mesh sizes, you can consistently achieve powders typically ranging from 20 to 120 mesh, depending on your specific requirements.
Is the temperature control unit necessary for all materials?
While not always necessary, the optional temperature control unit is highly recommended when processing heat-sensitive PVC formulations or running the machine at maximum capacity for extended periods. It prevents material from melting or degrading, ensuring consistent powder quality and protecting the equipment.
