Automatic Cement Rotary Kiln For Calcination Production Line
The rotary kiln produced by Zhongke has the calcining system
equipment through technology innovation, which adopts the most
advanced hydraulic catch wheel, high precision of measurement
piston pump, flow speed control valve, and contact graphite piece
of sealing device at home and abroad, In order to improve the
degree of automation, kiln head adopts industrial TV watching fire,
analog fluorescent screen for process flow, and calcination zone
adopts the infrared scanner, directly reflecting the calcination
situation in computer . All these new technology has a strong
intuitive sense in use, easy to operate. Reliable and stable
thermal condition improves the operation rate of the equipment.
Compared with the same specification of equipment, the operation
rate increases by 10%, the yield increases by 5%-10%, and the heat
consumption decreases by 15%.

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.
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.
