    Brief Introduction of Rotary Kiln:

    Rotary Kiln Furnace belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
    Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; Baking high-alumina mine in the refractory material factory; Baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant.

    Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

    Features of Rotary Kiln :
    excellent quality ;
    large capacity ;
    low consumputon ;
    good after-sale service.

    Working Principle of Rotary Kiln:

    Heat exchange in a Kiln Rotary may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat exchangers to encourage heat exchange between the gas and the feed. These may consist of scoops or "lifters" that cascade the feed through the gas stream, or may be metallic inserts that heat up in the upper part of the kiln, and impart the heat to the feed as they dip below the feed surface as the kiln rotates. The latter are favoured where lifters would cause excessive dust pick-up. The most common heat exchanger consists of chains hanging in curtains across the gas stream.
