Comparison of Grinding Media-Cylpebs versus Balls

Adding Zirconium Silicate Grinding Media Beads. An extremely small number of ceramic beads would be broken by high-speed impacts after long time of grinding. It is required to make up the bead load at regular time. Sieve out and weigh the broken beads, then add fresh ones of same weight.

Effect of ball load and size distribution on grinding and ...

Sep 01, 2013· A 1:1 mixture of two make-up ball sizes shows the bimodality of the ball size distributions, consisting of two populations derived from large and small make-up balls. By the same reasoning, a tri-modal ball size distribution appears when the make-up balls are a 1:1:1 mixture of three ball sizes. Download : Download full-size image; Fig. 5 ...
