Calculation of a ball mill load Considering that ball bed has a porosity of 40 % the actual ball volume is considered to be 21-24 % of the empty mill Now in order to get an efficient milling action 80-110 % of the pores in the ball bed must be filled with the actual particles to be ground

Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced

Aug 02 2013In 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

The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface The tool radius on each side of the cut will leave stock referred to as a scallop The finish of the part will be determined by the height of the scallop amd the scallop will be determined by the stepover distance

Ball mills are used in chemistry and in industry to grind hard solids to a very fine powder They are very similar to rock tumblers Basically the idea is to rotate a container filled with heavy metal balls that crush the substance that you want to grind Ball mills can be used to grind ceramic material crystalline compounds and even some
