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.

The results of extensive investigations carried out on industrial semifinishgrinding plants indicated that the specific power consumption of the ball mill could be decreased by about 20% when lowering the ball charge filling ratio from about 30% to about 20%. However, the throughput is decreased also by about 20% (Schnatz and Knobloch, 2000).

For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

As a result, operating costs in a cement plant will be reduced. Ball mills used in the cement industry are inefficient grinding technologies. Any small improvement in the operation of ball mills can lead to significant annual energy savings (Tiggesbӓumker and Müller, 1983, Viswanathan and Reddy, 1992, Schnatz and Knobloch, 2000).
