Product Description

Wet Process Cement Rotary Kiln for Calcined Dolomite in Cement Industry

We provide the full range service including design, manufacturing, installation. We design and manufacture equipment for new type dry method cement production line, for which the capacity varies from 50t/d to 3000t/d.

Our Features:

1.High Efficiency

Cement production line adopts advanced technology and equipment to raise technical level and to ensure design indexes. New five-stage cyclone pre-heater system, high efficiency air girder grate cooler, multi-passage pulverized coal burner, Davison heat temperature fan, jet pulse dust collector, as well as chain-board elevator, chain conveyor adopted in this production line can ensure that the technology is advanced compared to other production lines with the same scale.

2.Saving Energy
Measures have been taken to save energy and reduce consumption. using chain-board elevator and air slides, reliability of the system is enhanced and conveying energy consumption is decreased.

3.Environmental protection
Effective measures have been taken to guarantee strict environment protection standards. Different efficient dust collectors are set at all dust producing points according to different characteristics of waste gas.

4.High degree of automation  
There is no manual operation in the process of mill running, which realizes the automatic control with long-term, stable, effective, makes milling process more stable, realizes fine work of production.


 

PRODUCTION TECHNOLOGY

Mined limestone is delivered to the crusher for crushing by the belt conveyor, limestone after crushing ,clay, iron powder etc will be ground into powder by ball mill or vertical mill, and then transported by air delivery chute to raw meal homogenization silo for storing and further material mix. Raw meal shall get into the preheating decomposition system after homogenization where decomposition rate is about 95%, and raw meal is calcined into clinker in the rotary kiln, the formation of clinker. Clinker, gypsum and mixture is ground into qualified fineness cement in the cement mill. Powder classifier is adopted to adjust the fineness of cement, realizing energy saving production. Cement packing machine and automatic loading machine are used for bagged cement delivery, and cement bulk device for cement canning leaving factory.
