The cylinder of rotary calciner kiln is formed by rolled steel, and the refractory lining is designed for cylinder body, which is located in a predetermined inclination with the horizontal line supported by two wheels. One ring gear is fixed on the inner cylinder in the vicinity of the feed end by spring plate, under which there is a pinion meshing with it. Rotary calciner kiln is widely used in roasting dolomite, kaolin, bauxite, refractory material, cement, limestone, titanium powder, alumina, mineral, activated carbon, coke, slag, magnesia, zinc oxide, special cement, etc. Rotary calciner kiln (commonly known as rotary kiln), belongs to the class of building materials equipment, is one of the hosts of the active lime production equipment, and its main role is further roasting pre-heater materials to achieve the maximum decomposition of materials.
The rotary calciner kiln can be divided into cement kiln, metallurgy and chemical kiln, lime kiln, titanium dioxide calciner kiln and talc powder calciner kiln according to different materials. The cement kiln is mainly used for calcining cement clinker, can be divided into dry tppe cement kilns and wet type cement kiln. Metallurgy and chemical kiln is mainly used in magnetic roasting of iron ore in steel plant and metallurgical industry; the roasting of high alumina of vanadium bauxite and aluminum clinker, aluminum hydroxide in refractory plant; oxidizing roasting of chrome, nickel and iron; the roasting of chrome ore and chromium ore and other minerals in chemical plant. Lime kiln is used for roasting active limestone and light burned dolomite in steel plant and ferroalloy plant.
