Feed Size VS Ball Size - Grinding & Classification ...

A 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.

Effect of Grinding Media on Milling

Effect of Ball Diameter, or Rod Diameter Variation The first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter, upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling; these curves being deduced from the data of Coghill and Devaney.

the total mass of milling balls was ~100 g, and the num-ber of balls was N b ~ 450. In the Retsch PM-200 mill, a ball with a mass m moves over an elliptic trajectory with a current radius R(t) and acts upon a particle or the mill wall with a force f(t) = 4π2mω2R(t). An analysis of the mechanics of ball motion shows that (11) where κ = 8π3aN b
