Commonly known as the rotary kiln, the rotary calcining kiln is also called the rotary dryer, belonging to construction equipment. Depending on the materials, the rotary kiln falls into three types: the metallurgy kiln, the lime kiln and the cement kiln.
The cement kiln is mainly used for calcining cement clinker, classifying into the dry method production equipment and the wet type production equipment. Metallurgy kiln is widely used in steel works in the metallurgy industry for magnetizing roasting of poor iron ore; oxidizing roasting of chromium and nickel iron ore; roasting high aluminum vanadium and soil ore pellets in refractory plants; roasting clinker and aluminum hydroxide in aluminum manufacturers and roasting chrome ore and powder in chemical plants. The lime kiln (i.e. the active lime kiln) is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite.
The cement kilns mainly fall into two types: one is horizontal cylinder device(with gradient) and since it can make gyroscopic motion, it is also called rotary kiln; the other is vertical without rotation (also called the shaft kiln).
Rotary kiln is a kind of thermal equipment, can be used to dry material, in some particular smelting non-ferrous metal smelting equipment is also important. In smelting process used in the rotary kiln breed is very much, each type of furnace temperature, atmosphere, pressure, smoke gas, pigment type, fuel consumption parameters difference is very big, but on the whole basic structure similar, all is a drive through the drive through the small gear drive a straight cylinder on the big gear, keep turning, the cylinder body in rotary kiln brick refractory material is various, in some high temperature in the rotary kiln, due to resist high temperature material corrosion, erosion and wear, use magnesite chrome brick, magnesium aluminum brick, high alumina brick, etc., these brick of the thermal conductivity, the kiln body heat loss, in order...
