Working Principle

Feeding: Slag is introduced into the center of the rotating grinding wheel.
Grinding:
Migration toward the periphery by centrifugal force.
Compression by hydraulic rollers.
Drying:
Hot air injection via a ventilated ring.
Classification:
Selection by high-efficiency separator.
Fine powder → Bag filter.
Coarse particles → Recycling.
Control:
Automatic regulation of key parameters.

This complete solution enables optimal recovery of industrial by-products while ensuring productivity and environmental friendliness.
