Rotary dryer information 

 Rotary dryer can reduce coal moisture from 40-50% to less than 5%, fuel can be coal, natural gas, oil. rotary coal dryer consist of shell, front and rear supporting wheels, feeding and discharge device, gear device  and gear cap.  

Because of the adoption of reasonable working parameters, the rotary dryer, manufactured by our company, can save 10-15% energy and increase production by 10-15%.

Working Principle of  Rotary coal Dryer:

Rotary dryer’s heat source is a combustion apparatus. It adopts direct flow heating with heat source from firing unit. The material to be dried is pushed back immediately by spiral board after going in the shell from feeding tank or feeding chute. Because the drier is installed in an inclined position, material flows to the back end under gravity and rotation force. At the same time, it is lifted by board repeatedly and thrown down accordingly, which makes the material form an even curtain, so that it can exchange heat sufficiently with the heat flow. At last, water in the material is dried by repeatedly scattering:

Technical Parameters of  Rotary coal  Dryer:

the technical data will change according to raw material features 

Besides, there are woold rotary dryer, coal slime rotary dryer, sand dryer, gypsum dryer, chicken manure dryer in our company, welcome you inquiry us.

Rotary dryer whole plant

Usually, whole rotary dryer plant includes conveyor, rotary dryer, dust collector, if raw material moisture is 80-90%, dewaterer will be used first.

Normal rotary dryer inside ( inside structurer will be different according to raw material features)
