The difference between cast steel ball Iraeta Grinding

(5) Simply speaking, the cast ball is the heat-resisting ball (suitable for dry grinding, such as the ball grinder in cement plant), and the forged ball is the corrosion-resisting ball (suitable for wet grinding, large mines, power plants, etc); the cast ball is suitable for the 1.5-3.8m grinder, while the forged ball is suitable for 1.5-11m grinder.
