2. Resistance to overload ability, cylinder smooth operation and high reliability, lower fuel consumption and dry cost.
3. Rotary Dryer for Sale has the characteristics of high temperature resistant, high temperature hot air could be used for a rapid drying of material.

Main Usage of Rotary Dryer for Sale:

1. The series of Rotary Dryer for Sale could be used for drying excrement, fertilizer production, certain humidity and particle size fertilizer, as well as could bu used to dry other materiasl.
2. It is also widely used in building materiasl, metallurgy, chemical industry, cement industry which use this series of dryer to dry sand, distiller’s grain slag, charcoal, rice husk, ore slag, limestone, coal powder, slag, clay and other materials.

Working Principle: 

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.
