##tihuan2##Balls are now produced by casting, die forging, and rolling. Cast grinding balls find a limited application. Hot-rolled balls are produced according to a power-consuming technology, as the ball-rolling mill employs pre-deformed (rolled) billets. The process of ball die-forging is inefficient, as it requires great power and material …
