The ball charge mill consists of grinding media in various sizes to ensure optimum grinding efficiency and easy maintenance. The size distribution of the grinding media in the coarse grinding compartment is designed to just crush the coarsest particles in the mill feed material and to ensure adequate fineness of the material.

need for plant stoppages and/or high maintenance costs. Due to the limited space available in cement plants and also the high price of steel, small GCTs are required throughout the market. A small GCT can only be achieved by producing a fine water spray that evaporates faster than large droplets. There are two main.
