industrial rotary kiln limestone calcination furnace quick lime calcining kiln equipment factory

Product introduction and application

The rotary kiln produced has advanced structure. It can effectively improve preheating effect with its low resistance vertical preheater. After the material is preheated, the feeding decomposition rate can reach 20%-25%, thus can directly make use of 10-15mm fine fraction materials. The reliable airtight two-ends combination squama make the air leakage factor under 10%. The usage of compound refractory reduces radiation loss.Rotary kiln belongs to building material equipment, which can be divided into cement kiln,metallurgy chemical kiln and lime kiln according to different materials.

The structure characteristic of rotary kiln

1. The rotary calcining 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 supporting 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.

Working Principle 

Derui Rotary kiln cylinder composed of steel plate, cylinder body with build by laying bricks or stones of refractory lining, and horizontal line into slope, three belting leather in each block supporting device, in the material near the end belting leather across the inner cylinder with tangential spring plate fixed on a big gear ring, which is a small gear meshing. During normal operation, the main drive motor is transmitted to the open-type gear device by the main drive motor, which drives the rotary kiln.Materials are calcined from the end of the kiln. Due to the effect of tilting and slow rotation of the cylinder, the material is along the circumference of a circle and tumbling along the axial direction (from high to low) mobile, continue to complete the process, and generate the clinker kiln hood into the cooling machine cooling.The fuel is sprayed into the kiln by the kiln head, and the waste gas and materials produced in the furnace are exchanged for impact crusher, which is exported by the kiln tail.
