Rotary kiln refers to rotary calcining kiln, which belongs to the category of building materials equipment. It can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to the different materials handled.
Application fields:
Cement clinker calcination, metallurgical industry roasting, refractory roasting, chemical plant roasting
Applicable materials:
Cement, Lime, Depleted Iron Ore, Chromite, Nickel Iron Ore, High Bauxite, Chromite, Chromite Powder, etc.
Rotary kiln is a kind of high-temperature processing equipment, through continuous calcination to heat the material to high temperature. The industry categorizes rotary kilns as cement kilns, metallurgical chemical kilns, or lime kilns depending on their material processing applications. Cement kiln is mainly used for calcining cement clinker, which is divided into two categories: dry cement kiln and wet cement kiln. The metallurgical industry primarily uses metallurgical chemical kilns to magnetize roast poor iron ore in steel plants. Chemical plants employ them to roast chrome ores and chrome powders, while refractory plants utilize these kilns for high alumina-vanadium ore roasting. Aluminum plants apply them for clinker and aluminum hydroxide roasting, and they also serve in oxidizing chromium and nickel iron ores. Iron and steel plants, ferroalloy plants, and related industries use lime kilns (active lime kilns) to roast active lime and calcine dolomite.
Rotary kiln is a cylindrical container with a slight inclination to the horizontal plane, the material is fed into the kiln shell by the kiln head for calcination, the fuel is injected from the kiln tail for combustion, and the hot air is blown into the kiln from the kiln tail, which impacts the raw material directly, and due to the inclination of the kiln shell and the low-speed rotation, the raw material is tilted along the axial direction from the high end to the low end of the circumferential direction of flopping, mixing, and the material is calcined into the maturity through the decomposition, calcining, and cooling, and is discharged from the low end.
