Metallurgical Rotary Kiln Equipment

Metallurgical rotary kiln, also known as metallurgical chemical kiln or metallurgical kiln, is mainly used in the metallurgical industry, iron ore lean iron magnetization roasting; chromium, nickel iron ore roasting; refractory plant roasting high metallurgy and aluminum roasting clinker, hydrogen alumina, chemical plant roasting chrome ore and chrome ore powder and other minerals.
Metallurgical rotary kiln performance characteristics:
The new type metallurgical rotary kiln has the advantages of simple structure, convenient and reliable production process control, less wearing parts, high operation rate and high product quality of the kiln.
1. The kiln body adopts the high-quality calm carbon steel or alloy steel roll and automatic welding;
2. Wheel, roller, open gear alloy cast steel;
3. Sliding bearings using large gap not scratch bearing;
4. The transmission uses hardened gear reducer, flexible diaphragm coupling, DC motor drag;
5. Using hydraulic wheel;
6. Kiln head, kiln tail respectively by laminating and cylinder pressure tight seal;
7. Slow drive.
Metallurgical rotary kiln used by the fuel:
According to their status, can be divided into: 1. Solid fuels, such as coal, coke, etc .; 2. Liquid fuels, such as heavy oil, kerosene, diesel; 3. Gas fuels such as liquefied petroleum gas, producer gas, natural gas.
When the metallurgical rotary kiln is in normal operation, the main drive motor transmits power to the open gear unit via the main decelerator to drive the rotary kiln. Materials from the kiln (cylinder of the high end) into the kiln calcination. Due to the inclination of the cylinder and the slow rotation, the material is tumbling both in the circumferential direction and in the axial direction (from the high end to the low end) to generate clinker which is cooled by the kiln hood into the cooler. Fuel from the kiln head into the kiln tail, the exhaust gas generated after combustion and the exchange of materials, derived from the kiln tail.
