Crush and pre-homogenization
Crushing cement production process, most of the material to be crushed, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials, cement production, mining the particle size after the large, high hardness, so the broken limestone crushing the material in the cement plant occupies a more important position.
In Cement process,most of the raw materials used are extracted from the earth through mining and quarrying and can be divided into the following groups: lime (calcareous), silica (siliceous), alumina (argilla- ceous), and iron (ferriferous). Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. The plant must minimize the transporta- tion cost since one third of the limestone is converted to CO2 during the pyroprocessing and is subsequently lost. Quarry operations consist of drilling, blasting, excavating, handling, loading, hauling, crushing, screening, stockpiling, and storing.We provide crushing screening, grinding machines,such as jaw crusher,cone crusher,ball mill,vertical roller mill.
