Working Principle

Feeding: Uniform distribution of raw materials in the center of the grinding wheel
Grinding: Migration to the periphery by centrifugal force
Compression by hydraulic rollers
Classification: Separation by dynamic separator
Fine powder → Collector
Coarse particles → Recycling
Drying: Hot air system adaptable to material humidity

This advanced technical solution enables the efficient and sustainable production of high-quality mineral powders, while optimizing operational costs and environmental impact.
