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.

Stone Crusher: Limestone crusher Limestone is the main raw materials for making cement, so we need
the limestone crusher to crush limestone to small particle sizes to
make cement.
Raw mill: it is used to crush limestone particles and additive
materials
Coal crusher and coal mill: They are used for crushing and grinding coal into powder in
cement plant.
Gypsum crusher and mill: In cement plant, they are used for crushing and grinding gypsum
into powder.
Cement mill: Ball Mill: They are used to grind cement clinker into powder to make cement.
