Rotary kiln

    Rotary kiln refers to a rotary calcination kiln (commonly known as a rotary kiln), which belongs to the category of building materials and equipment. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns, and lime kilns according to the different materials they process. Cement kilns are mainly used for calcining cement clinker, and are divided into two categories: dry method cement kilns and wet method cement kilns. Metallurgical and chemical kilns are mainly used for magnetization roasting of poor iron ore in steel plants in the metallurgical industry; Chromium and nickel iron ore oxidation roasting; Refractory material factory roasting high alumina vanadium earth ore and aluminum factory roasting clinker and aluminum hydroxide; Chemical plants roast minerals such as chromium ore sand and chromium ore powder. Lime kiln (also known as active lime kiln) is used to roast active lime and light calcined dolomite used in steel and ferroalloy plants.
