Durable But Not Expensive Sintering KilnSintering Kiln

 

Introduction:
Sintering rotary kiln is mainly used for cement clinker, cement kiln dry process production of cement kiln and wet two categories. Metallurgical rotary kiln / chemical rotary kiln is mainly used for metallurgical industry, iron and steel plant iron ore magnetizing roasting; chromium, nickel iron oxidizing roasting; refractory material factory roasting high bauxite ore and aluminum roasting clinker, aluminum hydroxide; chemical plant roasting chrome ore and chrome powder ore; lime kiln (active lime kiln for active lime) roasting iron and steel plant, ferroalloy plant and light burned dolomite.
 
Technological process:
1. Ore from reservoir by electronic belt weigher, belt conveyor, stable bin, lock air valve is directly fed into the kiln rotary kiln, kiln tail only stable bin, to reduce the investment.
2. The ore into the rotary kiln is first heated, ore flow reverse movement in the kiln and the heat in the heating zone, ore is heated to a temperature reduction to the reduction zone.
3. The reduction zone flame temperature control in 1000 ℃ hot atmosphere, temperature control 700 ℃ and reducing gas reaction is reduced to magnetite reduction.
4. After entering the cooling zone, and to meet the gas, gas discharged by preheating, kiln ore after being cooled, the continuous bucket conveyor cooled, into the reservoir to be selected.
 
Structural characteristics:
1. Support device: the spindle structure is advanced, provided with an automatic temperature measuring device and an electric heating device, at the same time with mobility support for choice;
2. Block wheel device: divided into mechanical and hydraulic thrust roller two. Hydraulic wheel blocking device is equipped with the advanced hydraulic control system;
3. The transmission device: with single or double drive transmission. DC motor or frequency conversion speed control motor speed, reliable operation, high efficiency and energy saving;
4. The cylinder wheel plate: shell plate has the stationary type, adjustable and floating plate, has the advantages of simple structure, easy maintenance, disassembly characteristics exposes not to hurt the cylinder;
5. The sealing device: according to different design kiln type has a variety of seal for selection. Cylinder compression seal, spring compression seal, graphite block, graphite sealing spring hammer block sealing, flaps, axial labyrinth seal and labyrinth seal the seal, which is characterized by the cylinder body movement and swing of the adaptability, good sealing effect.
