Sand crushing rate, grain type roundness improvement and regeneration effect

Wheel type foundry sand reclamation method is the regeneration of the old dry sand a relatively new method, which is truly green energy saving regeneration. This method combines sand crushing rate, grain type roundness improvement and regeneration effect and good. With the invention of new adhesives and wide application of sand  polycrystalline diamond  increasing the difficulty of the 20th century, 90 years after the grinding wheel  synthetic diamond  method achieved rapid development. However, for wheel-type sand reclamation law mechanism of regeneration, study abroad is not much, and no mature theory to draw on, this paper attempts to explore the mechanism of the regeneration method.
