Cement Grinding

Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set.

Ball Mill

With dry grinding, these mills often work in a closed cycle. A scheme of the conical ball mill supplied with an air separator is shown in Fig. 2.13. Air is fed to the mill by means of a fan. Carried off by air currents, the product arrives at the air separator, from which the coarse particles are returned by gravity via a tube into the mill.
