Introduction of Cement Production Line
The cement production line includes vibrating feeder, jaw crusher,
impact crusher, vertical mill, preheating system, cement rotary
kiln, cement ball mill, packing machine and so on.
All the necessary equipment in this line can be provided by our
factory. We have cement production line experts to design specific
solutions for your reference.
Material Needed for Making Cement:
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 crushed 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.
Detailed Process of the Cement Production Line
1. Crushing and Preblending
In the cement production line, most of the material need to be
broken, such as limestone,clay,iron ore and coal. 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. 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.
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.
