Ball mills are the classic among grinding systems: They are used in about 90 % of all installations worldwide. The ball mill impresses with its simple principle and low maintenance requirements: it is robust, durable and has a high operating reliability. By using a separator in the closed circuit, the efficiency can be additionally increased.

High pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc.) and cement grinding stages. The energy consumption is kW h/t and about 10 kW h/t when recycling of the material is HPGR consumes 3050% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.

Ball mills for finish grinding cement usually consist of two compartments. An intermediate diaphragm separates both compartments from each other. The 1. compartment is filled with coarser balls and lifting liners and is supposed to pre grind coarser particles. The 2. compartment is the fine grinding chamber and is equipped with a finer ball ...
