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".
A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill .

Recognize important considerations in ball mill selection. Reading & Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition.
Oct 18, 2006· What it is the optimun speed for a ball mill ? - posted in Pyrotechnics: I have done a ball mill, recenly finished, but the motor has too rpms, is too fast for use in a ball mill (the pvc cylinder that i use, left of the shafts). With the motor i will use a 40 mm pulley, because i have a 50 mm driven pulley, in one of my two shafts.
Aug 15, 2012· There is a formula to calculate optimum speed. There is a calculator on passfire which is fairly convenient. The formula was published in Lloyd Sponnenburgh's booklet on ball milling, though he's said it originally comes from commercial information and literature on industrial ball mills.
The optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. For the dry powders used in pyrotechnics, the optimum speed will be 65% of the critical speed. Using the interactive calculator on this page will help you determine the optimal speed for your mill without having to reach
