ROTARY DRYER SYSTEM

Listing ID #3745161

The rotary dryer is one of the most common types of industrial dryer, it is a cylindrical shell usually constructed from steel plates, slightly inclined and is usually operated with a negative internal pressure to prevent dust escape. Large quantities of granular material up to particles of 10 mm or larger that are not too fragile or heat sensitive or cause any other solids handling problems are dried in rotary dryers.Rotary dryer system manufacturers, Rotary dryer system manufacturers
Solids introduced at the upper end through the feed hopper and screw feeder assembly, material start moving towards the lower or discharge end. Depending on the arrangement for the contact between the drying air and the solids, a dryer may be classified as direct or indirect, co-current or counter-current. Feed material lifting flights of various shapes is constructed inside the shell to shower the solids in order to ensure contact with the hot air. These flight configurations vary from spirals to straight flights depending upon the material to be dried.
