Rotary Dryer Machine

Description

Rotary Dryer Machine is a type of industrial dryer used to reduce or minimize the moisture content of the material it is handling by bringing it into contact with a heated gas.

The dryer is made up of a rotating cylinder or shell, a drive mechanism, and a support structure.

The cylinder is inclined slightly with the discharge end lower than the material feed end so that material moves through the dryer under the influence of gravity.

Material to be dried enters the dryer and, as the dryer rotates, the material is lifted up by a series of fins lining the inner wall of the dryer.

When the material gets high enough, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

Rotary dryers are a highly efficient industrial drying option for bulk solids, and they are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.

Rotary dryers can be custom designed to suit the unique processing needs of the material, whether low- or high-inlet temperatures, short or long residence times, counter-current or co-current flow.

They have many applications but are most commonly seen in the mineral industry for drying sand, stone, soil, and ore.
