The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100 passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh) thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work

Mar 10 2011 · We have a similar mill. Pregrinding with hammer crusher and mono-chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding. This is the raw mill not the finish mill. So Wi should be 11 and density of 2.67 as normal kiln feed.

The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote click here for our metallic media or here for our non-metallic media.
Chat OnlineMill Steel Charge Volume Calculation
We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below or
