Hot selling silica sand dryer

silica sand dryer is Bochuang's major product, with professional technology support and all-around service.

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

rotary dryer is made up of a large rotating cylindrical tube, the rotary dryer 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 dryer under.

Working principle of silica sand dryer:

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

The silica sand and the hot air into the silica sand dryer with same direction(known as co-current flow) or different direction(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 silica sand dryer is called a direct heated rotary drier, 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 rotary drier, the rotary dryer known as an indirect-heated type, often, indirect heated rotary driers are used when product contamination is concern
