rotary kiln manufacture with high efficient products

manufacturer 

 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.

The structure chracteristic of ourcompany is:

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.
