Cement Rotary Kiln
Zhongke brand rotary kiln is the main equipment for calcining
cement clinker and it can be used widely for cement industry,
metallurgy industry, chemical industry, etc. The rotary kiln is
composed of the shell, the supporting device, the supporting device
with thrust roller, the driving device, the movable kiln head, the
sealing device at kiln tail, the combustion device, etc. It has the
simple structure and reliable operation, at the same the production
process of the rotary kiln can be controlled easily.
We can supply Zhongke brand cement machine (titanium90 pigment
kiln, sintering furnace, industrial furnace, kiln, acid pellet)
made by Hena Zhongke Engineering & Technology Co., Ltd. whose
specifications are Φ3.2×52m,Φ3.5×54m,Φ4.0×60m,Φ4.3×64m,Φ4.8×74m and
Φ5.0×78m and used for 8000t/d, 5000t/d and 2500t/d new dry basis
complete rotary kiln equipments.

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
2. 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
