    World most popular stable operation cement rotary kiln/YZ1828 Cement rotary kiln for Cement Making Machine  

 

Introduction:

 

 

     Rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln

 

are with simple structure, convenient and reliable control of the producing process,with little wearing parts

 

and high running rate. It is the equipment calcining the high grad cement in the cement factory. The rotary

 

kiln is widely used in the metallurgy,chemical industry,construction and other industries.

 

 

 

 

Features:

 

 

1) The rotary kiln is an inclined rotary cylinder, the raw material enter the cylinder through the high end of the machine,then move in with the movement of of the rotary kiln. Therefore, the rotary kiln is a conveying equipment.

 

2) Rotary kiln is a combustion device.

 

 

3) Rotary kiln has the function of heat exchange.

 

4) Rotary kiln has the chemical reaction function.

 

5) The rotary kiln has the function of degrading and re-using the waste.

 

 

 

 

 

 

The structure chracteristic of ourcompany is:

 

 This series of rotary kiln is the large-size advanced international calcining kiln & furnace which is developed by

 

our company and many scientific research institutes such as Beijing General Reserch Institute of Mining &

 

Metallurgy, Changsha Research Institute Of Mining & Metallurgy, Suzhou Sinoma Reserch Institute of Non-

 

metallic Mining Industry, etc. Compared with the rotary kiln with the same specification made by the traditional

 

technology, this series of torary kiln can make the production capacity increase by 30%, make the heat

 

consumption reduce by 40% and make the discharged flue gas temperature<250 °C , so it is convenient for

 

collecting dust and meeting the modern environment protection needs about energy saving and consumption

 

reducing. This rotary kiln is widely used for extracting nickel from laterite,  calcining the activated limestone,

 

oxidized pellet, magnesium oxide, aluminum oxide, titanium dioxide, etc.

 

 1. The rotary kiln shell design fully take into consideration of the corner at shell flexible supporting to extend

 

the lifetime of refractory bricks and castings.

 

2. Adopt supporing roller bearing with big diameter and small ratio between length and diameter to improve

 

the reliability. The bearing is automatic self-sligning bearing.

 

3. The better sealing effect of new type open gear hood sealing type.

 

4. The spring lamination overlying type lexible sealing, double layer spring lamination sealing increase the

 

heat insulation layer to improve the reliability and lifetime.
