The machine is suitable for sand temperature cooling of resin sand, sodium silicate sand and clay sand.Hot sand falls into the orifice plate of the equipment bed body. While moving along the direction of vibration, the blast system pumps cold air from below the fish scale plate to make the hot sand boiling. The air contacts the hot sand sufficiently. The water gas in the hot sand is taken away and discharged from the vent to achieve the purpose of cooling. The heat exchange between sand and air in the boiling state is 6-10 times larger than that in the static state, so the boiling cooling bed is an ideal heat exchange device.
