To sum up, the grinding pill has obvious advantages over other products in manufacturing and raw material selection, and has the characteristics of high manganese steel. At the same time, there are no holes and cracks in the abrasive particles, and the hardness of the abrasive particles is balanced. Comparatively speaking, other products, such as steel balls and cast steel balls, have poor toughness, short service life, high cost and relatively small application scope. The above advantages are enough to show that the grinded steel shot is much stronger than other shot products.
