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%.
Rotary dryer Application
Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials, metallurgy, and chemical industry.
Rotary dryer is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, the dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.
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.
