ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.

The tendency was for the throughput of AG mills to increase as the feed Fgo was increased, whilst the opposite was true for SAG mills with ball charges in excess of about 5% by volume. SAG mills with ball charges < 5% exhibited an increasingly weaker AG mill type response as the ball charge approached 5%.

If the 30–80 mm pebble generated during autogenous grinding is used as the medium to crush the ore, the process is called pebble grinding. The density of pebble is less than that of steel ball, and its friction coefficient and contact area with the ground ore are greater than those of steel ball, so pebble grinding process has strong grinding force but …
