Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

How to Improve Cement Ball Mill Performance in Closed

The ball diameter should be different according to the aging degree of the inner liner: new liners bring grinding balls to higher height, so the ball size can be smaller. It can be seen from the experiment that when a grinding ball with a diameter of 70 mm falls freely from the height of 40 cm, its potential energy can completely crush a clinker particle with a diameter of 25 mm.

3 Types of Grinding Media for Ball Mills FTM Machinery

The so-called two-stage ratio is to use two different sizes of steel grinding balls with a large difference in diameter to carry out the grading. The multi-stage is suitable for the materials with small particle size and good abrasive property, while the two-stage ratio is suitable for the materials with large particle size and poor abrasive property.
