Dust-extraction Grinding Unit

The dust-extraction grinding system utilizes a high-speed rotary blade and fixed blade to achieve impact, shear, and grinding in a single process, this design delivers superior crushing efficiency while generating a powerful airflow inside the chamber.



Key Features

  •  Multi-stage crushing - Combines impact, cutting, and abrasion for uniform particle size.

  •  Active cooling effect - Airflow reduces heat buildup, ideal for heat-sensitive materials.

  •  Adjustable fineness - Screen mesh determines final particle size(Custom meshes available).

  •  Closed-loop dust control - Meets OSHA/ATEX standards for workplace safety.

Applications 

Widely used for processing Pharmaceuticals(APls, excipients), Chemicals(Pigments, resins), Food & Spices(Powdered flavors, heat-sensitive additives), Industrial powders(Coatings, polymers).

Technical Advantages

  •  Material: SS 304/SS316L/SS430(cGMP compliant). 

  •  Fineness range: Custom available. 

  •  Dust collection rate: More than 99.3%.

  •  Special design: Low-noise operation, easy screen replacement.  

Why This System?

  •  Higher yield - Airflow assisted discharge reduces material retention.

  •  Lower energy consumption - Optimized blade geometry cuts power usage by 15% vs conventional mills. 

  •  Safer operation - Eliminates explosive dust risks in chemical/pharma applications.
