The device is mainly used for drying new sand.Its main fuel is coke and cold gas.At work, sand is fed into the drum by the feeder through the feed chute on the upper part of the fuel furnace. At the same time, the heat released by fuel combustion enters the drum under the action of the suction fan.Sand in the roller through three return movements, heat exchange with hot air, so that water evaporation, and finally through the discharge funnel out of the drum, drying process produced by the dusty gas from the dust collector processing back.

The device has flexible layout, good drying effect and convenient maintenance. According to the requirements of the user, when using coke as fuel, the direction of furnace door can be made into positive, left and right three forms.When using gas as fuel, direct injection from the front into the combustion chamber.
