The reasons of cement mill needs timely cooling

Cement mill internal temperature is too high will have two problems:

First, reduce production efficiency, because the cement sticky ball phenomenon will become serious as the temperature increases.

Second, cement grinding is a mixture of clinker and gypsum grinding, gypsum from the regulation of cement setting time. Gypsum temperature is too high will lose crystal water, into hemihydrate gypsum or anhydrous calcium sulfate, the solubility of the original composition is completely different from the regulation of the cement setting time will have a greater change, the cement may be acute condensate or even flash condensate not available.

Therefore, it is necessary to control the temperature of the cement mill, generally below 100 °C and not exceeding 120 °C.
