Limestone crushing: limestone is the main raw material for cement making, but since natural limestone is usually big, we use cement limestone crusher to crush them into small particles.

Bauxite crushing: bauxite is the addictive. For making cement raw materials, bauxite is crushed by cement equipment into powder. Then bauxite particles and limestone particles together are ground into raw powder by raw mill.

Coal crushing: coal powder is used to be processed into cement clinker. Raw coal is crusher by cement plant then ground by cement coal mill.

Gypsum crushing:gypsum powder made by gypsum crusher and gypsum mill is put into cement clinker together with coal powder, and then the cement raw material enters into the cement mill for fine grinding.

1. Crushing and Preblending

In the cement production line, most of the material need to be broken, such aslimestone,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 the cement production line, 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 plant consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.

3.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.

4.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. 

Our company provides Feeder, crusher, predistributing bin, batching station, vertical mill, kiln feeding for raw material, preheater, rotary kiln, coller, clinker bin, cement mill and so on. these equipment is the main part of the cement production line.
