Working Principle

Pre-crushing: Primary crushing by jaw crusher
Conveying: Elevator → Storage hopper
Feeding: Electromagnetic vibrating feeder
Grinding:
Compression of materials between suspended rollers and a crown
Centrifugal force ensuring progressive grinding
Classification:
Separation by turboselector
Fine powder → Cyclone collector
Coarse particles → Recycling to the grinding area
Control:
Complete system under controlled vacuum

This proven technology guarantees continuous production of homogeneous powder, ideal for demanding industrial applications.
