Energy saving Cow dung, chicken dung, sheep dung dehydration drum dryer
Rotary Dryer Introduction:
Rotary dryer is widely used to dry materials in industries like cement, mine, construction, chemical, food, compound fertilizer, etc. Thermocouples are installed in feeding and discharging units to control temperature. Temperature change of the dryer also can be indicated by the thermometer, which is convenient for temperature control inside the dryer ( it is usually 250-350℃).
Application of rotary dryer
Powder & particle: Sands, limestone, stones, clay, mineral filter cake, coal, iron sulphate, filter cakes, fly ash, gypsum etc.
Damp and sticky material: Coal slime, sewage sludge, bentonite, Kaolin etc.
Corrosive material: Distillers ‘grains, Fertilizer, animal dung, slag etc.
Biomass material: Sawdust, wood chips etc.
Specifications

4.Working Principle of rotary 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.
