Rotary kiln is a rotary calcining kiln, which is a relatively important type of building material equipment in modern industry. The following mainly understand the different applications of rotary kilns in five industry fields:

1. Building materials industry: Rotary kiln is used to calcine clay, limestone and slag drying, etc. In the production of refractory materials, rotary kiln is used to calcine raw materials, which can stabilize the size, increase the strength, and then process and shape.

2. Ore dressing process: use a rotary kiln to magnetize and roast the lean iron ore, so that the original weak magnetism of the ore is changed to strong magnetism, so as to facilitate the magnetic separation.

3. Chemical industry: Rotary kiln can be used to produce soda, calcined phosphate fertilizer, barium sulfide, etc. It has the advantages of low energy consumption, less electricity consumption and the availability of medium and low grade phosphate rock.

4. Cement production: One of the most important uses of rotary kiln is in the cement industry. The entire production process of cement is the process of burning the prepared raw meal after grinding into clinker under the high temperature of the rotary kiln.

5. Environmental protection: There have been examples of using cement kilns to incinerate hazardous waste and garbage 20 years ago. This method not only reduces the amount of waste and makes it harmless, but also uses waste as fuel, saves pulverized coal, and reduces waste. Resource.
