dust generated from the first grinding process for the raw material and the second grinding process for the cement clinker in the cement plant. The results of elementary chemical analysis are expressed in weight percent of oxides. The raw material dust of the first grinding process primarily consisted of CaO (), SiO2 (%), Al2O3
with appropriate chemical and physical properties. Cement raw materials are received with an initial moisture content varying from 1 to more than 50 percent. For the Carolinas Cement Plant, grinding of blended raw materials occurs in an inline raw mill in which kiln exhaust gases are used to heat and dry the raw materials.
MATERIAL HANDLING GRINDING A raw mill is the equipment used to grind raw materials into "raw mix" during the manufacture of cement. Dry raw mills are the normal technology installed today, allowing minimization of energy consumption and CO2 emissions. Process of raw mill in grinding of raw material and silo storage 1.

cooler, crushers, grinders, and material handling equipment. When the raw materials have high alkali or chloride content, a portion of the collected dust must be disposed of as solid waste, to avoid alkali buildup. Leaching of the dust to remove the alkali is rarely practiced. Grinding mill operations also result in particulate emissions.
The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
