Swedish Society of Technologists describing his "ball" test. This rapidly be-came known as the Brinell test and became universally used in the metal-working industry. Currently, many machines have been devised for making these tests more rapidly and accurately, but the principle has remained essen-tially unchanged.

Full load test: after the half-load test and everything is normal, add enough medium inside the ball mill cylinder gradually increase the ore amount and run at full load for 10 20 hours.Study of BBD Ball Mill Load Measure Method Based on Rough Set The simulation test shows that the proposed method can accurately reflect the BBD ball mill load ...

The ball mill no-load test means the machine runs without steel ball and mineral materials. The idle time generally cannot be less than four hours normally it needs to run for 8 to 16 hours. The longer the test time the better the grinding of the main bearing and the gear tooth surface.

The Bond ball mill test is designed to predict power in wet ball mill grinding circuit operating at a 250% circulating load. However, moving away from this condition reduces the accuracy of the test. Further, the Bond ball mill test does not predict the behavior of large rocks in a grinding circuit where the mode of breakage is impact dominated.

Bond Work Index Procedure And Method . This grindability test or bond ball mill work index procedure is used to determine the bond work index of minus six mesh or finer feed ore samples these equation application methods are used to process 12 ore samples in a ball mill using a standard ball charge below describes in general terms the bond work index procedure used by a professional ...

Though, there are small differences in the mill speed (N: 0.6 versus 0.7) and ball load (J: 0.5 versus 0.4), in our opinion the main factor is the ball size distribution: a single size ball charge versus a ball charge made up of balls of three different sizes. The void space in the ball charge, the relative movement of different layers of balls ...
