1. Description of the rotary kiln

Therotary kilnproduced by Songshan Machinery has advanced structure. It can effectively improve preheating effect with its low resistance vertical preheater. After the limestone is preheated, the feeding decomposition rate can reach 20%-25%, thus can directly make use of 10-15mm fine fraction limestone. 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.

Cement rotary kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcining. Rotary kiln is used for calcining of high aluminum vandal ochre in refractory material industry; for calcining of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.

2. The structure of rotary kiln

Therotary kilnmainly consists of kiln body, loading device, burning device, unloading device, electronic appliance, dust collector, etc. Different lime kilns have different structures. Their process flow are almost same. But the equipment value has big distinction, of course the results are different.
