Automatic Cement Rotary Kiln For Calcination Production Line
Rotary Kiln refers to rotating calcination kiln, belongs to construction material equipment. According to different materials, rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln. The cement kiln is used for makeing cement clinker and there are dry and wet methods to make cement. Cement is essential materials for construction buiding, it is made from stones which mainly is limestone, coal.
Cement kilns are used for the pyroprocessing stage of manufacture 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. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.
