Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are ...

Cement kilns are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

High-speed coal mill: Its rotating speed range is 500-1500 r/min. Commonly used high-speed coal mills include fan coal mills and hammer coal mills. Among all coal mills, cylinder-type steel ball coal mill is widely favored because of its good adaptability to all kinds of coal, strong drying ability, simple structure, high reliability, and easy
