The rotary dryer is mainly used in the fields of building materials, mineral processing, metallurgy, chemical industry, etc., it can be used to dry materials with specified moisture and size.

Rotary Dryer Working Principle

The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams.When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

Rotary Dryer Unique Features

High degree of mechanization, large production capacity, can be continuous operation;

Less failure, low maintenance cost, low power consumption;

Efficient drying of materials with high moisture contents;

Handles a wide size range of materials with extended residence times;

Design permits highest possible drying temperatures;

High thermal efficiency;

Wide range of application, good uniformity of products.
