It was found that a rod mill grind to approximately minus 6 mesh produced a feed to the pebble mill which could be ground efficiently with a minus 2-½ plus 1-½ inch pebble. Grinding power requirements totalled 10.7 net kwh/ton of rod mill feed and pebble consumption in the 4 ft diameter pebble mill was 3.1% of the total circuit feed.

Addition of pebbles to a ball-mill to improve grinding

When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate.

Ball mill Wikipedia

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

The investigation has demonstrated that the grinding capacity of a mill is maintained when balls are replaced by pebbles, up to about 30% of the charge volume. The energy dissipation and the surface area for grinding are reduced as the pebble volume increases, and it reasonable to assume that the pebble wear compensates for these changes.

Mill (grinding) — Wikipedia Republished // WIKI 2

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

THE OPTIMISATION OF PEBBLE GRINDING

Pebble mills are used at the mine for secondary grinding, using a pebble feed size of 65mm/35mm. Semi-batch tests were performed on a bulk sample of the ore, using a 1.2 m diameter mill. Various mill speeds and two pebble feed size ranges were tested (i.e. 65mm/35mm and 44mm/28mm).Various size fractions of pebbles were marked using spray paint and weighed before and after each experiment to

The plant data and the pebble wear measured in the experiments was used to calculate the flow of pebbles required to maintain a 25% pebble volume in the ball-mills. The average pebble consumption was calculated to be about 5% of the feed to the ball mill circuit. This will vary with ore hardness and abrasiveness. The implication here is that
