product description

 

In the metallurgical industry, rotary kiln can be divided into internal heating rotary kiln and external heating rotary kiln according to different heating methods. The material of the externally heated rotary kiln is not in direct contact with the flame and the flue gas. The heat source is between the heating furnace and the cylinder, and the material is heated by the heat transfer of the heat-resistant steel cylinder wall. The lining of the heating furnace is refractory fiber, which can save energy and reduce consumption. It is especially suitable when dealing with requirements such as high toxicity, high smoke concentration and high product purity.

 


 

Technical performance and characteristics

 

Structural optimization

The device is compact in structure, easy to operate and easy to maintain. The outside of the heating furnace has a heat preservation cover, and a heating chamber is formed between the heating body to make the cylinder heat evenly, and heat loss is reduced. The tail end is supported by the supporting wheel, the contact area is large, and the heat rising amount can be released in time to reduce the damage of the cylinder body by internal stress.

 

High operating rate

By controlling the heat source, the use efficiency of the externally heated rotary kiln will be higher. The working principle of the externally heated rotary kiln is more convenient to clean, and the fuel is saved, which helps the environment to protect and reduce the heat due to excessive heat. Causes damage to the equipment.

 


 

working principle

 

The material to be burned is uniformly fed into the kiln cylinder through the feeding mechanism of the kiln hopper. Under the driving of the transmission device, the material advances along the axial direction of the cylinder with the rotation of the cylinder, and the material is turned over to make the calcination uniform. . A heating chamber is arranged outside the cylinder. The heat generated by the calcination is transferred to the material through the cylinder, and the material is decomposed, dried, calcined and calcined at a high temperature. The calcined material is discharged through a discharge valve and used after being cooled and packaged.
