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.
The Cement Production Process
Finish Milling of Clinker. Finish milling is the grinding of clinker to produce a fine grey powder. Gypsum (CaSO 4) is blended with the ground clinker, along with other materials, to produce finished cement. The gypsum controls the rate of hydration of the cement in the cement-setting process.
