Increasing the efficiency of particle size reduction could

CLINKER GRINDING IN CEMENT PRODUCTION

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.
