50TPH Rotary Dryer for Sand
Introduction of Sand rotary dryer
It made up of Stove, Main Rotary Body, Screw Conveyor, Cyclone Separator, Air-lock, and Fan and matched Pipes which can realize to reduce the moisture from 60%-10%.
The heat generator combined fan is not included in our quotation.
Mainly used in building material, metallurgy, chemical plant, cement plant for drying of limestone slag, coal powder, slag, and clay stone.
The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
Working principle of the sand rotary dryer
Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.
The barrel is installed with slope to horizontal line.
Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together.
Materials go to the lower side by gravity when the barrel rotates.
Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
