Why Disc Milling — Not Just Granulation
A practical four-step process focused on stable operation and consistent output.
Metered Feed
Pre-crushed granules enter through a vibratory feeder that controls the load rate.
Direct-Drive Grinding
Material passes between high-speed rotating discs with micrometer-adjustable gaps.
Temperature Control
Integrated water jacket and air cooling keep the chamber below critical thresholds.
Why Rumtoo Disc Pulverizers
Direct Drive — No Belts
Eliminates belt slippage and replacement downtime for higher efficiency.
Temperature Protection
Sensors monitor bearing temperature with automatic shutoff to prevent damage.
Segment Disc Design
Grinding discs use modular segments that are individually replaceable.
Problem-Solution Fit
Unstable feedstock conditions reduce production consistency.
Engineering configuration is matched to material variability and throughput targets.
Inconsistent quality creates downstream process risk.
Process design focuses on output stability for downstream stages.
Frequent intervention increases labor and maintenance pressure.
Service-friendly structure supports efficient operation and maintenance.
Scaling capacity can disrupt existing line performance.
Modular integration supports phased expansion and retrofit planning.
Typical Applications
Rotomolding Feed
LLDPE/HDPE powder preparation targeting 35-60 mesh for uniform walls.
PVC Rework
Convert rigid PVC scrap into fine reusable powder for extrusion blending.
Technical Specifications
| Parameter | Specification | Notes |
|---|---|---|
| PM-400 | 150-300 kg/h | 20-120 mesh |
| PM-600 | 300-600 kg/h | 20-120 mesh |
| PM-800 | 500-800 kg/h | 20-80 mesh |
Output depends on polymer, feed size, target mesh, and cooling configuration.

Frequently Asked Questions
What is the difference between a pulverizer and a granulator?
A granulator makes flakes; a pulverizer grinds flakes into fine, flour-like powder.
Why is cooling important?
It prevents polymer softening and degradation during high-speed grinding.
