Clinker Grinding. Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills.

Feb 21, 2019 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.
