AI Technical Summary
Traditional foundry sand grinding equipment is inefficient and has poor uniformity. It is difficult to adjust the grinding pressure and speed according to different sand molds, resulting in some sand particles not being fully cleaned and easily causing sand particle breakage and equipment wear.
It adopts a multi-stage abrasion structure, with the main abrasion belt and the secondary abrasion belt having opposite textures. Combined with an elastic support to adjust the pressure and an ultrasonic pressure electro-osmosis device, it achieves multi-dimensional abrasion and dynamic pressure adjustment, in conjunction with cleaning agent spraying and infiltration treatment.
It significantly improves the cleanliness and uniformity of foundry sand, extends equipment life, enhances grinding efficiency and reagent utilization, and adapts to the regeneration needs of different sand molds.
