and ball mill bond work index, the low JK Axb and Ta values and the high UCS data are indicators of resistance to breakage in a SAG mill. III-96 Crushing work indices greater than 30 kWh/t are typical. On the basis of the benchscale data, a traditional SABC circuit was expected to consume approximately 30 per cent more power than typical "Bond"

Testwork Bond ball mill work index SAGMILLING COM. The bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the bond work index the test is a lockedcycle test where ground product is removed from test cycles and replaced by fresh feed the test much achieve a steadystate before completion
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

Norton surface grinding wheels and segments are a universal choice for heavy, rapid stock removal and production work to precision tolerance operations. Our surface grinding wheels come in a variety of abrasive grain types and bonds and can increase grinding performance anywhere from 100-600%. Grinding Wheels - Harbor Freight Tools.
The Bond Ball Mill Work Index (W i) was measured as 24 kW h/t at a test screen size of 106 μm. The feed top size determines the largest ball size required for particle breakage. Bond found that for a given feed size the largest size ball required could be estimated using Eq.
