CiteSeerX — IV

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): An increase of over 10 % in mill throughput was achieved by removing the ball scats from a single-stage SAG mill. These scats are non-spherical ball fragments resulting from uneven wear of balls with included porosity. 30t of scats were removed from a total charge load of 70t.

Effect of ball mill size on media wear

Correlation of scale-up from small-scale batch laboratory mills to large-diameter industrial mills was established by performing two series of laboratory and pilot plant grinding tests using a magnetic taconite ore and a siliceous sulfide ore. In one series, controlled batch grinding tests in 203-, 508-, and 914-mm (8-, 20-, and 36-in.) diameter mills were carried out followed by a

What Affects How High a Ball Will Bounce?

15/4/2020When a ball hits a hard surface, it sends force to the ground. The ground then returns that force, causing the ball to bounce. A soft surface returns less force, causing a smaller bounce. If a ball bounces repeatedly on its own without being pushed, gravity makes

The effect of ball size on mill performance

If it is also assumed that the mean overall values of S i for a mixture of balls is the weighted mean of S i values for each ball size, equations are derived for calculating this mean value. As an example, the results are used in a mill simulation to show the quantitative effect of different ball mixes in a two-compartment cement mill versus a uniform mix over the whole mill.
