Description

Note: Limestone Bond Index: ≤13kWh/t

Working Principle:
The motor drives the grinding table to rotate through the reducer. Raw materials fall to the center of the grinding table from the feed inlet, while hot air enters the mill through the air inlet.
Under centrifugal force, materials move toward the edge of the grinding table and are crushed by grinding rollers in the annular trough. The crushed materials are then lifted by high-speed airflow at the air ring.
Large and coarse particles fall back to the grinding table for re-grinding. Fine powder passes through the dynamic-static separator with the airflow and is finally collected by the powder collector as finished products.
Meanwhile, hot air fully dries the moist materials during processing, ensuring the finished powder meets the standard moisture requirement.
