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