Specifications

Quartz sand rotary dryers is Yongxian' s major product, so professional technology support and all-around service can be offered to you

Quartz sand rotary dryers is handling by bringing it into direct contact with a heated gas

Rotary dryers is made up of a large rotating cylindrical tube, the rotary dryers slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the rotary dryers under

Working principle of quartz sand rotary dryers:

Material to be dried enters the rotary dryers and as the rotary dryers rotates, the material is lifted up by a series of internal fins lining the inner wall of the rotary dryers, when the material gets high enough to roll back off the fins, it falls back down to the bottom of the rotary dryers, 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 co-current flow) or toward the feed end from the discharge end (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 rotary dryers is called a direct heated rotary dryers, 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 dryers , the rotary dryers known as an indirect-heated type, indirect heated rotary dryerss are used when product contamination is concern
