Keep the hardness just right. When we choose wear-resisting grinding media ball, often be the hardness problem of the grinding media ball.About the hardness, not the bigger the better, is the appropriate hardness value. Simply put, the higher the hardness, the greater the impact reaction during the process of falling, increasing the ball loss.
Aug 03, 2021 During the use of the ball mill, the choice of grinding media is very important. Grinding media is affected by many factors such as material, filling amount, shape, particle size, etc. In the grinding process, using different grinding media for different materials, models, and equipment can reduce production costs and improve production efficiency.
Optimization of mill performance by using. This test also shows that by feeding the mill with a too dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate a variation in total ball angle can be detected and linked to grinding efficiency and charge expansion this could help the operator to make the right decision and keep the mill
