Rotary Dryer IndustrialRotary DryersManufacturer from Pune

The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Based on the configuration, rotary dryers can be classified as co-current, counter current, direct fired and indirect fired. Explanation of each configuration is given below:

Rotary Dryers an overview ScienceDirect Topics

In the rotary cascade dryer, the material is placed in a rotating cylinder through which a hot air stream is passed. Flights on the cylinder wall lift and cascade the product through the air. In a variant, louvers are used instead of flights so that the product is mixed and rolled instead of dropped.

Things to Consider When Selecting a Rotary Dryer

Direct heat rotary dryers pass a stream of drying air through the drum. The drying air is directed in either a co-current flow (flowing the same direction as the material), or counter-current flow (moving in the opposite direction of the material). Direct dryers are the most common choice for drying bulk solids, because they are so efficient.
