Rotary Drum Dryer

Skype:zkbm1998

Rotary Drum Dryer Introduce:

ZKBM series rotary drum dryer is also called roll dryer, which is handling by bringing it into

direct contact with a heated gas.The dryer is made up of a large, rotating cylindrical tube,

The dryer 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 of Rotarty Drum Dryer:

Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series

of internal fins lining theinner wall of the dryer. When the material gets high enough to roll back

off the fins, it falls back down to the bottom of the dryer, 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 cocurrent flow), or toward the feed end from the discharge end (known as countercurrent flow).

The gas streamcan be made up of a mixture of air and combustion gases from a burner, in which

case the dryer is calleda direct heated dryer. Alternatively, the gas stream may consist of air or

another (sometimes inert) gas that is preheated.When the gas stream is preheated by some means

where burner combustion gases do not enter the dryer, the dryer known asan indirectheated type.

Often, indirect heated dryers are used when product contamination is a concern.
