Main Use of raw coal rotary dryer: 

Raw coal rotary dryer is mainly for dealing with material in large quantities. 

As reliable operation, operating flexibility, adaptability and large capacity, this raw coal dryer is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries. 

This generally adapted to granular powder materials. Through the way of mixing material partially, this raw coal dryer also can be used for drying sticky paste-like materials or materials with high water content. 

Structure of raw coal rotary dryer: 

Raw coal rotary dryer consists of drum shell, front and rear roller ring, gears, block roll, pinion, discharging part, reducer, motor, warm air duct, feed-in chute, furnace body and other components. 

Besides, we can design gas producer, combustor chamber or supporting elevator, belt conveyor, quantitative feeder, dust collector cyclone, induced draft fan, etc. 

Working principle of the raw coal rotary dryer: 

Material to be dried enters the raw coal dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the lignite coal dryer. 

When the material gets high enough to roll back off the fins, it falls back down to the bottom of the raw coal 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 raw coal 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 raw coal dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
