The above results prove that composite secondary milling (using a 25/75 pebble/ball mixture) can also be applied in ballmills in SABC circuits, without a detrimental effect on productivity. The benefits of reducing energy and ball consumption are similar to those reported in Part 1, where the feed was relatively fine, and the top size (feed ...

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

Bob and Hassannoori have answered your question. SAG mills will contain some degree of steel media, generally 8 12%. SAG Mills tend to have large diameters and short lengths. Pebble Mills, also called Tube Mills, use pebbles to grind grit to powder, and are long Mills with a small diameters. Pebble Mills contain no steel grinding media

Pebble mill. A tumbling mill that grinds or pulverizes materials without contaminating them with iron. Because the pebbles have lower specific gravity than steel balls, the capacity of a given size shell with pebbles is considerably lower than with steel balls. The lower capacity results in lower power consumption.

The idea of using a mixture of balls and pebbles, at a mill speed suitable for ballmilling, was revisited in this investigation, using a normal spectrum of pebble sizes (1975 µm). Batch tests in a pilotscale mill ( m diameter) were used to compare ballmilling to various ball/pebble mixtures.
