sand dryer is bochuang major product, with professional technology support and all-around service.

sand dryer 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.

Sand dryer maintechnicalparameters

Working principle of sand dryer:

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 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 sand falling.

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