TESTING OF GRINDING BODIES IN THE BALL MILL

2019-5-7  In 2017, we have published a whole series of articles in which we have described in detail the grinding ball testing procedure. In this article we will briefly list the main points that you should know and work out carefully before starting the tests.. The tests are divided into three types: laboratory tests are done in laboratory (small) mills.

Small-Scale Tests to Characterise Ore Grindibility

The SAG mill comminution (SMc) test was developed by Steve Morrell. It is an abbreviated drop-weight test, which can be performed at low cost on small rocks or drill cores. cores are normally cut into ¼ cylinders using a diamond saw and the test is performed similarly to the standard drop-weight test procedure, except that a single size fraction is tested. The test can be performed at various rock sizes, the minimum acceptable top size being 16mm. The recommended rock size is 26.5- 31.5mm, which requires preparing about 20kg of samples, but only 5kg is actually tested, and all the products and unused material can be reused for metallurgical testing. Testing of smaller rocks or drill core requires significantly smaller weight. A bulk sample, or essentially any size of drill core, is adequate for the test.

2018-12-4  The test mill (Fig. 2) is 0.6 m (2 ft) inside diameter by 0.2 m (0.67 ft) inside length. It is operated at 65 percent of critical speed. Each ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second. Drive losses (a roller bearing between the mill and the torque meter) have been measured to be negligible. Media charges were prepared by weighing and counting out the number of balls needed in each size class, determined by their individual weights and the specific gravity of steel. Twenty-seven equilibrium media charges are currently available for testing. Examples are given in Table 1.The test mill

The MacPherson Autogenous Grindability Test is a continuous test performed in an 18” (46cm) semi-autogenous mill, with an 8% ball charge and controlled by sound at 25% mill charge level. At test completion, the products are submitted for particle size analysis, and the mill charge is dumped and analysed to evaluate any coarse and/or heavy material build-up in the mill. Although the importance to achieve a steady state in a grinding test is widely accepted, the MacPherson test remains the only small-scale AG/SAG test that offers this opportunity. It offers a cost-effective alternative to pilot plants for continuous testing
