Automatic Cement Rotary Kiln For Calcination Production Line
Rotary kiln has simply structure, easy operation in producing, less wearing parts, high efficiency,it's used in the cement plant to calcine high grade cement, at the same time can be used in metallurgy,chemical,constructure ect. rotary kiln features in strong structure, stable operation, high-quality products from the kiln, and we can offers advanced efficient shaft preheater, five-grade cyclone preheater.
Cement is essential materials for construction buiding, it is made from stones which mainly is limestone, coal.
The cement kiln is used for makeing cement clinker and there are dry and wet methods to make cement.

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.
In cement plant, to produce cement need seven steps.
1. Crushing and Preblending
In cement plant, most of the material need to be broken, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material in cement production, after mining the size of limestone is large, with high hardness, so the limestone crushing plays a more important role in cement plant.
2. raw material preparation
In cement plant, producing each 1 ton of Portland cement need grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement palnt consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.
3. raw materials homogenization
Adopting the technology of homogenization could rationally get the best homo-effect and afford an eligible production to the demand
4. preheating and precalcing
Preheater and calciner is key equipment for precalcing production technique.
5. burning cement clinker in a rotary kiln.
The calcination of Rotary Kiln is a key step of cement production , it makes directly influence on the quality of cement clinker.
6. cement grinding
Cement grinding is used for grinding cement clinker (and gelling agent, performance tuning materials, etc.) to the appropriate size (in fineness, specific surface area, said), optimizing cement grain grading, increasing the hydration area, accelerating the hydration rate to meet the requirements of cement paste setting, hardening.
7. cement packing
Cement Plant equipments
In the cement manufacturing plant, not only the crushing machinery, but also the grinding machine is used as cement producing equipment.
