As we all know, the circumgyrate cement kiln belongs to the building material equipment class ,which is a kind of rotary kiln. But most people do not know much about some professional knowledge of the rotary kiln, now let me do a simple introduction for you .
According to the different materials dealt ,
rotary kiln can be divided into cement rotary kiln, metallurgy chemical rotary kiln and lime kiln.
Cement rotary kiln is the main equipment of cement clinker dry and wet production line.
The composition of the cement rotary kiln
It is composed of cylinder parts, gear, gear wheel support device, kiln liner, kiln seals, kiln and fuel devices.
According to the different heating methods, the cement rotary kiln can be divided into internal heating and external heating these two categories . The materials that in the internal rotary kiln are in direct contact with the flame and flue gas , the space between the head tail cover and cylinder is flexible seal,which can completely eliminate dust and drain materials. The multi-file can also be adopted to support,the barrel length ups to 60 meters, maximum temperatures ups to 1600°C. the applicable fuels are liquefied petroleum gas, natural gas, coal gas, fuel oil, pulverized coal, coal. The materials are heated in the external rotary kiln can't be direct contact with the flame and flue gas, furnace linear adopts the refractory fiber. limited by the heating method and the barrel material, The general barrel length is less than 15 m. The yield is smaller, the applicable heating type are electric, gas, nd other materials .
