Rotary dryers are used for drying wet powders and cakes, which are easily breakable and dispersible. The rotary dryer consists of a rotating drum with angle lifting blades which lift the feed as the drum rotates and showers it in the stream of hot air flowing through the drum.
The rotary dryers can be used as calciners using direct or indirect firing.
GMP plants are offered for pharmaceutical, food, and biochemical applications.
Typical applications of rotary dryers include silica sand, bagasse, minerals, coconut powder, etc.
