# calculating ball weight in a ball mill

• ##### 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 tear.

• ##### Optimum choice of the make-up ball sizes for maximum

The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles. Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the

• ##### A Method to Determine the Ball Filling, in Miduk Copper

Average Ball Abrasion For calculating of the average ball abrasion, average weight of balls after abrasion test was deduced by average balls weight before abrasion. At first, ball filling in the mill was spot 1% and the number of balls in mill was estimated as shown below (Equations 7, 8 and 9). 𝐴𝑏 = 4335.44-3636.78=698.66 g (7)
