[0002] A rotary kiln refers to a rotating calcining kiln, which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry-process cement kilns and wet-process cement kilns. Metallurgical chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore, oxidation roasting of chromium and nickel iron ore in steel plants; roasting of high-alumina vanadium ore in refractory plants and roasting of clinker and aluminum hydroxide in aluminum plants; and roasting of chromium ore sand and chromium ore powder in chemical plants. Rotary kilns are also used in the existing technology to dry industrial sludge.
