cement factory rotarykiln limekiln is used for making 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 nickle in the steel factory,baking high-alumina mine in the refractory material factory,baking chamotte and alumina in the aluminuium 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. Rotary kiln is composed of cylinder,gears,support device,kiln liner and kiln tail sealing equipment,kiln head hood and combustion. Cylinder as heated pivoting part, made of high-quality carbon steel plate,is supported on the support device tyre,and there is machanical or hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder.Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder.Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary gears,which makes cylinder gyrate more slowly.To prevent cold air come in and dust overflow,the reliable kiln tail and head sealing equipment is installed on feed and discharge end. Rotary kiln is a thermal equipment,heating materials, it is widely used in the fields of cement,nonferrous metallurgy, ferrous metallurgy,refractory materials,chemical materials,paper making. Product feature: support device:advanced shaft structure,automatic temperature measuring device and electrical heating.catch wheel:including two kinds:mechnical wheel and hydraulic pressure.Gears:single or double.control the rotating speed by buncher,DE machine and frequency variable motor.Be reliable,energy-saving and efficient.Cylinder tyre bolster:low bolster has three types:fixed,zoom and floating.The structure is simple,replacement is convenient and wont hurt cylinder.Sealing equipment:there are many kinds for choice according to kiln models,including air cylinder edge sealing,spring edge sealing,graphite block sealing and combination for above.The feature is adaptive for cylinder rotating and swing.And sealing effect is very good.Kiln head hood:including stationary type and flexiable type.
