Main equipment: raw material vertical mill, coal mill, cement rotary kiln, vertical cement mill
Process:
1. Crushing and Pre blending
limestone, clay, iron ore, coal, etc. Limestone is the largest amount of raw materials in cement production. After mining, the size of limestone is large with high hardness, so limestone crushing plays a more important role in cement plants.
2. Raw material preparation
In the cement production line, producing 1 ton of Cement need to grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, and gypsum).
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
The preheater and calciner are the key equipment for precalcing production technique.
5. Burning cement clinker in a rotary kiln
The calcination of the rotary kiln is a key step of the cement plant, which makes directly influences on the quality of cement clinker.
6. Cement grinding
Grinding cement clinker (and gelling agent, performance tuning materials, etc) is used to grind the cement to the appropriate size (in fineness, specific surface area, etc.), optimize cement grain grading, increase the hydration area and accelerate the hydration rate to meet the requirements of cement paste setting and hardening.
