Chat Online### Raw Material Drying-GrindingCement Plant Optimization

Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding. Compartments (filled with grinding media) are divided by a double diaphragm with flow control to utilize maximum mill length for effective grinding.

Chat Online### Overview of our mills · Christian Pfeiffer

The two rollers rotating in opposite directions exert very high pressure on the material effectively crushing and weakening the particles (microscopic cracks) so that the subsequent fine grinding is easier. When used as a pre-grinding system in ball mill circuits production increases of up to 100 and more can be achieved. Read more
