Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln), which belongs to cement building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical and chemical kiln and lime kiln according to different materials. Fodamon rotary kiln can be divided into ceramisite rotary kiln, metallurgical rotary kiln, chemical rotary kiln, lime rotary kiln, active lime rotary kiln and so on.
The technology of calcining ultra-fine kaolin in ceramsite rotary kiln at medium temperature (950 ~1050 C) is mature and advanced in China, which represents the development direction of ultra-fine kaolin calcination technology. This calcination technology has the advantages of low energy consumption, high output, dehydration, decarbonization and whitening of products, stable performance, and can be used in papermaking and coatings industries.
Metallurgical and chemical kilns are mainly used for magnetizing roasting of lean iron ore in iron and steel plants of metallurgical industry; oxidizing roasting of chromium and nickel iron ore; roasting clinker and aluminium hydroxide in refractory plants; roasting chromium ore sand and chromium ore powder in chemical plants.
Chemical rotary kiln is mainly used for calcining chemical clinker, which can be divided into two categories: dry process kiln and wet process kiln. Chemical rotary kilns are mainly used for magnetizing roasting of lean iron ore in iron and steel plants of metallurgical industry; oxidizing roasting of chromium and nickel iron ore; roasting of high-bauxite vanadium ore and clinker and aluminium hydroxide in bauxite plants; roasting of chromium ore sand and chromium ore powder in chemical plants.
Cement rotary kiln is mainly used for calcining cement clinker, which can be divided into dry kiln and wet kiln. Metallurgical and chemical kilns are mainly used for magnetizing roasting of lean iron ore in iron and steel plants of metallurgical industry; oxidizing roasting of chromium and nickel iron ore; roasting of high-bauxite vanadium ore and clinker and aluminium hydroxide in bauxite plants of refractory materials plants; roasting of chromium ore sand and chromium ore powder in chemical plants. Lime kiln (active lime kiln) is used to roast active lime and light-burning dolomite for iron and steel plants and ferroalloy plants
