    In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge. In the second compartment (and also in our one-compartment cement mills) we use a corrugated lining designed to obtain the maximum power.Grinding media for fragmentation and grinding of ores, rock and earth mass and other materials mostly in drum mills, for application in ore mining, construction and other industrial branches.
