Cast balls are better for drying grinding and forged balls are not. In a drying grinding circumstance, working temperature of balls can reach to 300 above which will temp the forged balls and therefore, the balls will lose hardness and have very high consumption rate. High chrome cast balls have a chrome content at least 10% and normally is 18%, which makes cast balls suitable for drying grind and high alkali circumstance. But for SAG, forged balls are much better because cast balls have lower resistance to impact. That's the reason cast balls are popular in cement industry and forged balls are popular in mining industry.
