What Is Rotary Kiln？

Rotary kiln is a common type of building materials equipment in industrial equipment. Mainly used for high temperature pyrolysis and conversion of chemical materials type. It is made of type cylindrical shaped equipment. It is placed at a slight incline from front to back. The material enters into the rotary kiln through one end, and then with the continuous rotation of the cylinder. The material keeps moving forward. Thus it is discharged from the other end. It can handle different types of materials. Rotary kiln can be divided into: metallurgical chemical kiln, cement kiln, active lime kiln and other types of building materials equipment. Rotary kiln plays a great role in waste treatment. It can achieve the recycling of resources.

The working principle of rotary kiln: materials under high temperature pyrolysis treatment and transformation process. Through the rotary kiln heated materials. Can achieve: drying, calcining, roasting, incineration, smelting, gasification and other recycling treatment effect. According to different material requirements can meet the needs of different processes.

Advantageous features of rotary kiln:

High efficient processing capacity: rotary kiln has a large filling volume and processing capacity. It can recycle and process a large amount of materials at the same time. It can meet the needs of large-scale production and processing. For example: cement clinker firing and waste mass treatment in cement production line.

High-temperature calcination capacity: The rotary kiln processes materials at high temperatures. Temperatures can reach hundreds or thousands of degrees Celsius. The rotary kiln can handle a variety of high-temperature treatment processes. For example: calcination, roasting, metallurgy, etc.,…

Continuous operation: the material is put into the kiln from one end of the rotary kiln. It moves gradually along the axial direction. The material is discharged from the tail end. Continuous production and processing can be realised This improves its production efficiency.

Heat energy conversion: rotary kiln has good heat energy utilisation efficiency after heat treatment of materials. In the cement calcination production line, the rotary kiln can be heated by coal, natural gas and other fuels. The heat energy of the flue gas produced is recycled and reused. Thus, the utilisation rate of energy is improved.

Customised design: It can be adjusted and optimised according to different process requirements. According to different materials, the treatment process is different. Rotary kiln speed, tilt angle, feeding and discharging methods can be adjusted.

Rotary kiln can be used in many industrial fields: cement, chemical, metallurgy, environmental protection, ceramics and other industries. It has the advantageous features of high production efficiency, strong adaptability, stable operation and so on. The design of rotary kiln should consider the characteristics of its materials. Energy energy consumption and other factors. It can ensure high efficiency, safety and environmentally friendly production and treatment process.
