small cover area and large capacity silica sand drum dryer

silica sand drum dryer machine is Bochuang major product, with professional technology support and all-around service. With many years experience in the field of drying, our dryer have a very good market and with good quality ,also competitive price.

silica sand drum dryer machine is handling by bringing it into direct contact with a heated gas.

rotary drier is made up of a large rotating cylindrical tube, the rotary drier slopes slightly so that the discharge The dryer's outlet is lower than

the material inlet in order to convey the material through the rotary drier under.

Working principle of silica sand drum dryer machine:

quartz sand to be dried enters the rotary drier and as the rotary drier rotates, the material is lifted up by a series of internal fins lining of the wall on the rotary drier,

when the quartz sand raising up by the lifting board,and will falls back down to the bottom of the rotary drier, passing through the hot gas stream when the quartz sand falling.
