Sales OnlineIf the circuit (cyclone overflow) P80 is close to a standard sieve size, simply select that size as the ‘size of interest’ Next, at the size of interest, from the analysis of the plant samples, calculate the amount of ‘coarse’ in the mill by taking the arithmetic average of the % coarse in the mill feed (CUF) and mill discharge (BMD)

Sales OnlineThe 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 .

Sales Onlinecircuit P80 target size) material in the ball mill It can be measured and then increased through pump and cyclone adjustments By so transferring the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is decreased The other factor that determines overall
