Quartz sand dryer and river sand dryer belong to a kind of drying equipment that generally uses single-cylinder structure, which are mainly used for drying the materials with certain humidity and granularity and widely applied in building materials, metallurgy, chemical industry and so on. 

Quartz sand dryer 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 process of quartz sand dryer:

After having been sent to the hopper through belt conveyor and bucket elevator, the quartz sand will be evenly and quantitatively sent to feed port of dryer through hopper feeder. The cylinder of quartz sand dryer should be in certain angle, thus the materials can slowly flow to the low end under the action of gravity. In the flow process, materials will fully contact with hot air, thus realizing the purpose of drying wet materials.

Working principle of the Quartz sand 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 the inner 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 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 dryer is called a 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 as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
