AI Technical Summary
Existing sand crushers are not efficient at crushing larger sand blocks, and the sand storage bins after sand crushing do not have a cooling function, which affects the efficiency of secondary use of molding sand.
A system consisting of a sand crusher, an elevator, and a cooling sand silo was designed. The sand crusher breaks up sand blocks by asynchronous vibration of the screen plate and grid plate, and the cooling sand silo discharges heat through the vent plate and guide hood to achieve preliminary cooling of the molding sand.
It improves the efficiency of sand removal and facilitates the secondary use of molding sand through cooling, thereby enhancing the utilization efficiency of molding sand.
