Cement Plant:
Cement is essential materials for construction buiding, it is made from stones which mainly is limestone, coal, gypsum and alumina (bauxite) in cement plant.
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 plant, we need not only the crushing machinery, but also the grinding machine.
Stone Crusher: Limestone crusher Limestone is the main raw materials for making cement, so we need the limestone crusher to crush limestone to small 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: 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.
