steel ball consumption in ball mill. aug 2019 calculation of ball mill capacity the production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting there are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain size hardness density temperature and of ball mill feed sample from plant survey. sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. mill speed: 35.2 rpm length of time of test: 363 seconds average torque reading: 1,056 in-lbs mill HP (1,056 in-lbs the minimal magnitude of ball size is calculated in millimeters from the equation: where db.max is the maximum size of feed is compression strength is modulus of elasticity is density of material of balls is inner diameter of the mill bodyball mill finish calculator. the ball mill finish calculator can be used when an end mill with a full radius 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 between cuts.
