Within the context of the study, a laboratory scale media wear measurement test procedure was developed for dry environment by utilizing 3 different mill dimensions. Briefly, 6 types of high chromium white cast iron grinding balls having 30 mm diameter were subjected to tumbling action at .
A range of ferrous grinding media compositions was subjected to laboratory marked ball wear tests in an ongoing research program at the Mineral Resources Research Center which was aimed at elucidating the responsible wear mechanisms during the grinding of minerals.
Grinding Media Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.
The Selection and Design of Mill Liners . Malcolm Powell*, ... Liners protect the mill shell from wear and transfer energy to the grinding charge, and a careful balance is required to optimise these conflicting ... Wear testing techniques and their drawbacks and limitations are discussed, along with new tests under development.
2 WEAR TESTS ON GRINDING BALLS testing has been developed which we be The balls tested were, in most cases, nom lieve makes possible an accurate estimation inally 3 in. in diam.
Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

94 x " balls; The optimum number of grinding balls is 285. However, the ball diameters vary due to wear. Therefore, the total ball number should be adjusted from time to time to ensure a total mass of grams. The grinding jar of the Bond Index Ball Mill measures 12″ x 12″ and has wellrounded corners. Module Rod Mill
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 nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.
The ball mill abrasion test (BMAT) promises to offer accurate prediction of relative service lives of wearresistant alloys for liners and grinding media in mineral grinding environments.

Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
BallonBlock ImpactSpalling Test A test that simulates the type of wear caused by repetitive impacts is the ballonblock impactspalling test. The testing machine drops steel balls repeatedly onto a test block, as described fully by Blickensderfer and Forkner. The impacts are concentrated onto one relatively small area on the test block.
