Get the Movement Principle of Limestone Dryer

Limestone dryer, also known as limestone rotary dryer, limestone rotary drum dryer and rotary drum dryer for limestone, is widely used to dry slag, carbide slag, limestone, clay, river sand, quartz sand, grain slag and other materials in building construction materials, metallurgy, ore beneficiation, chemical, cement and other industries. In order to keep up with the development of the times, limestone dryer equipment has been constantly in improvement and innovation, and the new type limestone dryers become more and more popular on the market. The new type limestone dryer machine not only has high working efficiency, but also can create more benefits.




Movement Principle of Limestone Dryer:

Material to be dried enters the rotary dryer, and as the dryer machine 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.
