raw material grinding in a cement plant

Raw Material Drying-Grinding - Cement Plant Optimization

Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.

Step 2 : Proportioning Blending Raw Grinding. The raw materials are analyzed in real-time using cross-belt analyzers and in the plant laboratory, blended in the proper proportion, and then ground even finer. Plants grind the raw materials with heavy, wheel-type rollers that crush the materials into powder against a rotating table.

Cement manufacturing - components of a cement plant

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
