Rotary kiln calcining kiln (commonly known as rotary kiln) belongs to building material equipment. Rotary kiln according to different processing materials can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Mainly used in cement kiln calcining cement clinker, at the production of dry and wet cement kiln to produce cement kiln two broad categories. Metallurgy chemical kiln is mainly used in steel plants and metallurgical industries depleted magnetic roasting of iron ore; chromium, nickel, iron oxidation roasting; calcined high alumina refractories plant soil vanadium ore and clinker roasting plant, aluminum hydroxide; chromium ore roasting plant and minerals such as chromium slag. Lime (that is, active lime) for roasting iron and steel plants, ferro-alloys plant activity and light burned dolomite lime.
