Rotary Dryer

The Main Types of Rotary Dryer:

Rotary dryer can be divided into wet material rotary dryer, sand dryer, sawdust dryer, coal dryer, coal slime dryer, bentonite dryer, ore concentrate dryer, wood chip dryer, cassava dryer, gypsum dryer, cow dung dryer.

The Handling Materials and Application of Rotary Dryer:

The rotary dryer is widely used for drying the chalk slags, coal powder, slags, clay and other materials in the building materials, metallurgy, chemical industry, cement industry. The rotary dryer has a better adaptability and can dry various materials with a simple and reliable operation.

The Advanced Inner Structure of Rotary Dryer:

The rotary dryer is mainly composed by the revolving body, lifting plate, driving device, supporting device, sealing ring and other components. So it has the advantages of reasonable structure, perfect in workmanship, high yield, low energy consumption, convenient to operate.

1. High mechanization, strong production capability and continuous operation

2. Excellent and simple structure, steady operating process under resistance of the drum, easy operation

3. Little malfunction, low maintenance cost and power consumption

4. Wide application range and good drying effect.

The sleeve column structure of the rotary dryer shortens the dryer length in multiple times. As the heat delivery area is greatly reduced, so is the heat consumption. However, the multiplication heat exchange area increases the heat performance. For those untouchable materials, the multi-drum rotary dryer machine or rotary drying machine provides inner smoke tube and annular smoke tube relevantly in the inner drum and external drum. These smoke tubes connect each other through radial tubes to increase high efficiency. It’s obvious that hot materials and cold medium, the rotary dryer is also known as sleeve type rotary cooler.
