Usage in Mineral Processing:
Minerals are firstly crushed by jaw crusher until they are crushed to suitable sizes. They are then equally fed to a ball mill with a hoister and a feeder. Later, they are further crushed and milled in the ball mill. Finally, fine minerals are classified by a spiral classifier with the principle that solid particles sink at different speeds in liquid.

Usage in Aerocrete Equipment:
Coal ash (or sand, stone powder) are conveyed to ball mill through electric vibrating feeder and rubber belt conveyor. Grinded coal ash (or sand, stone powder) is delivered to slurry tank for storage through a coal ash pump.
Lime is conveyed to jaw crusher by electric vibrating feeder and rubber belt conveyor. The crushed lime firstly is stored in a limestone storage silo with a bucket hoister. Then, it is conveyed to ball mill through a spiral conveyor. Finally, fine grinded materials are delivered to stock bin through a spiral conveyor and a bucket lifter.
