For drying the wet raw material it is necessary that prior to the mill start up the grinding plant is.heated for some time.Otherwise the cold grinding plant would take away too much heat from the drying process and the finish product would not be dry – handling problems in the meal transport and silo extraction would follow.
It then describes the industrial process for manufacturing cement, involving grinding raw materials like limestone and clay at high temperatures in a kiln to form clinker, which is then pulverized with gypsum to become Portland …
Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture.
