A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.

The abrasion mill test uses increments of milling time to generate a weight loss curve, the slope of which gives the abrasion resistance index. This new index, k s is compared with wet attrition and aggregate abrasion values for a suite of 11 rocks with wide ranging strengths. Los Angeles Abrasion Test results are briefly mentioned.

Steel ball bearings in the hardness test, a fundamental aspect of what is abrasion test, produce the abrasive action using standard steel balls that, when mixed with the aggregate and rotated in a drum for a specific number of revolutions, impact the aggregate.. The wear per age due to friction with steel balls is determined and is known as the abrasion value.

The different steps involved in abrasion testing for aggregates as per IS: 2386 (Part IV) 1963 are as follows: Step 1: Consider a specified amount of aggregate (5 kg), which is larger than mm size. Step 2: In this test we should consider charge balls (as per table 1) of specific weight which depends on the grading of aggregate.
