Why Are Forged Balls More Popular than Cast Balls? -

2017-11-29  Forged grinding ball can withstand the impact of more than 12 joules due to its high toughness. Lower wear. In the grinding process, cast grinding ball's surface may have the loss of circle, but forged ball won't. Cast grinding ball is made by pouring, which results in that there is a pouring port in each ball surface.
