Lab Rotary Dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material. The dryer is made up of a large, rotating cylindrical tube, usually supported by steel beams. 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 gravity. 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 air as it falls. This air 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 hot air can be made up of a mixture of air and combustion heat energy from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the hot air may consist of air or another (sometimes inert) heat energy that is preheated. When the air is preheated by some means where burner combustion heat air does not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers is also available to improve the overall efficiency.
Lab Rotary Dryer can be used to dry the following material:
a. Sawdust, grazing, leaves, sugarcane biogases, and animals’ wastes and so on. And it can be used in Chemical Plant, Mine, Metallurgy and other industries. For example, the ore, the scoria, coal, metallic powder, phosphor fertilizer, sulfur.
b. It can dry the granule materials which have special requesting and must dry in low temperature. For example, Vesicant; Lightweight Calcium Carbonate; Active Dust; Magnet Powder; Plumbago and so on.
