Brief introduction
This machine is mainly suitable for the cooling of green sand reclamation. The sufficient movement makes the temperature, humidity and composition of the old sand uniform, and completes the pre-mixing while cooling, so as to prepare the high-quality sand for pre-mixing.
The machine is compact in structure, stable in operation, low in noise and low in energy consumption; the crosshead that rotates in the opposite direction drives the scraper to mix the materials uniformly; the high-pressure air blows the old sand to a boiling state to achieve the best cooling effect; the opening degree of the discharge door Adjustable, can control emptying materials in the basin; can be used with the old sand humidification cooling system, blower, exhaust fan to form the old sand cooling unit, the cooling effect is ideal, the temperature of the old sand can reach room temperature + 10 ℃
Working principle
During work, the hot used sand that has been humidified (about 4-5% moisture) enters the machine body through the feeding port, is strongly stirred by the scraper, and moves in two circles in the pan; at the same time, from the ring The air inlet of the machine blows cold air into the machine and exchanges heat with the sand. The hot air is exhausted from the machine by the exhaust pipe on the top. The sand pushes the discharge door on the side wall to unload the machine.
