Chat Onlinea ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi-self locking taper.One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum.Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill.
Chat OnlineThe specific rates of breakage of particles in a tumbling ball mill are described by the equation s i = ax i (q(z), where q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in s, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form.
