This rotary drum dryer takes wet material and stirs it with bafflers that are uniformly distributed in the barrel. The hot air and the stirring motion expedites the drying process and quickly evaporates unwanted moisture.

Applications
This drying equipment is used for drying heavy particles in chemical, mining, metallurgy and other industrial applications. The stirring dryer is also suitable for special materials such as alcohol residue, calcium carbonate and active clays.
