1. Introduction. Grinding aids, first introduced into cement manufacturing in 1930 [], are surface-active substances that facilitate particle comminution during the milling process.In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard [].
The different cement types need to be put in separate storage silos before they are sent out in the market for selling. The grinding operation of the cement is carried out in cement mills located in the grinding plants. The grinding plants can be installed at a far away location from the clinkering plant. 2.6 Cement Dispatch
