Metallurgy rotary kiln
Capacity: 100-10000t/d
Applications: steel plant, refractory plant, aluminum plant, etc.
Metallurgy rotary kiln is a thermal equipment for drying, roasting, and calcining bulk or slurry materials. It is used in nonferrous smelting, iron and steel metallurgy, chemical industry, cement, and refractory industry; Especially in nonferrous smelting and refractory industry. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants of metallurgy industry.
Metallurgy rotary kiln shell is made of static carbon steel or alloy steel plate and automatically welded. The kiln tyre, kiln support roller and open gear of the equipment are made of alloy cast steel, and are also equipped with a slow drive device to make the calcination more sufficient. The sliding bearing adopts large clearance non-scratch bearing, etc. Reasonable technical configuration and excellent calcination technology.

Advantages of our metallurgy rotary kiln
Good calcination performance
The metallurgical rotary kiln has a good calcination effect on materials. The concentrate contains no impurities, high grade, strong pertinence and professionalism, and greatly improves the recovery and utilization rate of materials.
High output
The internal volume of the metallurgy rotary kiln has been increased by more than one time, the processing capacity of materials per unit time has been increased by more than three times, and the calcination efficiency is very high.
Lower cost
Our metallurgy rotary kiln is equipped with a special cooling device to ensure the cooling processing of the calcined material, the energy consumption and power consumption are very low, and the total operating cost has been reduced a lot.
Reasonable sealing system
Both the kiln head and the kiln tail are equipped with scale lamination and cylinder compression sealing devices to improve work efficiency. The design of the sealing device is relatively advanced and reasonable.
Good environmental protection effect
The design of the dust-proof device greatly reduces dust emissions and noise, improves the production environment in the metallurgical field, and has better low-carbon environmental protection effects.

Working principle of metallurgy rotary kiln
The cylinder body of the metallurgical rotary kiln is a cylindrical object with a certain slope, the slope is 3.5-4%, and the rotation of the kiln is used to promote the stirring of the materials in the rotary kiln, so that the materials are mixed and contacted with each other. The combustion of coal injection at the kiln head produces a large amount of heat, which is transferred to the material through the radiation of the flame, the convection of the hot gas, and the conduction of the kiln brick. When the raw material moves in the kiln, the movement mode of the raw material particles changes periodically, or they are buried in the material layer and move upward together with the kiln, or land on the surface of the material layer and fall down. But only when the raw material particles fall along the surface layer, the material moves forward in the kiln relying on the inclination of the kiln shell and the rotation of the kiln.
