Rotary dryer is mainly used in mineral processing, building materials, metallurgy, chemical industry and other departments. It is used to dry materials with a certain humidity or particle size. Rotary dryer has strong adaptability to material. It can dry various materials and equipment operation is simple and reliable, so it has been widely used.

Outstanding Advantages

Parts has long service life, uneasy to wear

a.The structure design of rotary dryer idler wheel is reasonable and it is adaptable to various lubrication methods. So the phenomenon of idler wheel worn and shaft broke are uneasy to appear. This shortens the replacement cycle of rotary dryer idler wheel and improves its service life.

b.Dryer barrel with high-hardness and high-toughness adopts high-quality steel material. So its wear-resistance is higher than other materials,

Rotary dryer

Strong drying intensity and high-efficiency

Because of the high airflow speed, meanwhile the materials disperse well in gas,so all the surface area of materials can be used as the effective drying area. Therefore, the drying area is greatly increased.

At the same time, because of the dispersion and agitation during drying make gasification surface is constantly updated. So the heat transfer process has strong drying intensity and high efficiency.

Excellent environmental protection performance

Rotary Dryer System has excellent sealing performance and it was equipped with a perfect dust removal device, which ensures a no dust overflow and good operating environment. The use of LX-type multi-composite lifting board makes materials present rain-like material curtain when they enter into the dryer inside. This increases the contact area of material and hot air and avoids the occurrence of heat.

Advanced structure, strong drying ability

The new internal structure strengthens the cleaning and heat conduction of the dispersed materials and eliminates the adhesion phenomenon inside the cylinder wall. Rotary dryer has stronger adaptability for the materials with large water content and strong viscosity.
