Sawdust rotary drying machine

Introduction:

sawdust rotary drying machine is handling by bringing it into direct contact with a heated gas. The equipment is made up of a large, rotating cylindrical tube,The drying machine slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.

Working principle:

Material to be dried enters the equipment, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the drying machine. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer machine, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the drying machine is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.
