This machine is mainly used for the cooling of old clay sand. The sufficient movement makes the temperature, humidity and composition of the old sand uniform. The machine has compact structure, stable movement, low energy consumption and good cooling effect. The high pressure fan makes the old sand in the boiling state to achieve the best cooling effect. The opening of unloading door can be adjusted to control the amount of material in salt. The machine and the old sand automatic temperature and humidification system and blower, induced fan, water system can constitute a complete and ideal old sand cooling unit.

According to the different installation position, the machine can be made into two ways of discharging materials: straight line type and vertical type. Both left and right unloading directions should be used when ordering.
