Effect of ball and feed particle size distribution on the ...

2018-6-1  The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate.

2012-3-1  We investigated the effect of seed particle size on membrane synthesis using ball-milled NaA zeolite seeds with different particle size. Tubular mullite supports were dip-coated separately by the original NaA particles and the ball-milled particles with ball-milling times of 1 h, 2 h and 3 h, which had average particle sizes of ∼2.8 μm, ∼1 μm, ∼0.5 μm and ∼0.3 μm, respectively.

2013-12-1  At a given rpm, there exists an optimum ball size to yield minimum particle size. The optimum ball diameter decreases from 5 to 2 mm as the rpm increases from 50 to 153. This result has been interpreted in light of the competition between the reduced kinetic energy of the colliding balls in the slurry (a negative source for milling efficiency) and the increased number of contact points of the smaller balls (a positive source for milling efficiency), which yields the optimum ball

The smaller size ball needs more power consumption in both cases. The calculated power consumption agrees with the measured one. On the other hand, gibbsite powder samples were ground with the planetary ball mill to investigate the grinding rate constant. The grinding rate constant is found to be well correlated with the power consumption.
