Rotary Drum Dryers
CHEMFILT's Rotary Drum Dryer offers a simple solution for continuous drying, cooing, roasting and heat treatment of particulate/bulk solids.
CHEMFILT's Rotary Drum Dryers are capable of handling large tonnage throughputs and are built to withstand rough, rigorous, continuous 24 x 365 hours of operation with minimal down time. Our engineering expertise in producing rugged, high quality, co-current and counter current units is in use by industries around the world.
Drying, roasting, heat treatment and cooing is achieved by passing the material being processed through a rotating horizontally inclined cylindrical drum. The stream of hot gas / air for drying and cold air for cooling, also, passes through the drum. As the drum rotates, the internals, Pusher Flights and lifters", fitted into the drum tumble, slide, lift and shower and cascades the material into the air stream. In co-current dryers, the hot gas/ airstream flows in the same direction as that of the product being dried, and in counter current models the drying gas/ air stream travels against the flow of the product being dried. In these dryers the product is directly exposed to i.e. in contact of the stream hot gas/air produced by the heat source.
