Nowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process.
Cement Grinding Stage
In raw grinding, a ball mill with a high efficiency separator is used to achieve uniform particle size in raw mix for the next stages of the manufacturing process. At the Cement Grinding Stage, 90 – 95% of the clinker is mixed with gypsum and ground in a Cement Ball Mill to produce quality cement OPC 43 and OPC 53. In case of PPC Cement ...
Optimizing cement grinding with chemical additives
Reducing the effects of inter-particle attraction forces of cement grains helps to keep particles from clumping together. This reduces void filling and improves the dispersion of the feed to the separator, both of which lead to enhanced grinding efficiency. For further advice, contact a cement production specialist.
