The major operations carried out in the cement raw material milling are as follows: Crushing of limestone, coal, and other materials. Storage arid blending of raw materials. Preparation of raw mix. Raw mix grinding and homogenisation. Pyro processing of raw materials in the kiln. Cooling and storage of clinker.
The wear resistance of raw material. The wear resistance of raw material refers to how easy the high energy ball mill is to grind the material. National standards stipulate that using Wi (kwh / t) represents the grinding index. The smaller the grinding index, the better the material is ground.
Grinding of cement raw material – material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm).
The tube mill comminutes raw materials by impact and friction between grinding balls, which hit raw materials as well as between grinding ball and mill lining. Many of this type mills have two grinding chambers for coarse and fine grinding. Grinding ball size and their distribution are designed and adjusted considering raw material conditions ...
Dry grinding requires approximately 30 % more energy / wt. of ground material. Dry mills need more mill volume than comparable wet mills. However, the increased metal wear of the grinding media and the mill liners for wet grinding, equalizes the additional energy costs of dry grinding procedures ~ 30 - 40 % of wear costs in wet grinding.
