Active lime production line refers to the production line of active lime manufacturers. General rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kiln is mainly used for calcining cement clinker. There are two types of cement kiln: dry production and wet production. The metallurgical and chemical kiln is mainly used for the magnetization roasting of lean iron ore in iron and steel plants of the metallurgical industry; the oxidative roasting of chromium and nickel iron ore; the refractory plant roasts high-alumina vanadium ore; And chrome minerals. Lime kiln is used for roasting active lime and light-burned dolomite for iron and steel plants and ferroalloy plants. The application of the rotary kiln makes the cement industry develop rapidly. Its technical parameters, performance and operating conditions, to a large extent, determine the quality, output and cost of the company's products.
