  • Technical Note Why is the Bond Ball Mill Grindability Test

    2015-12-27 · The Bond Ball Mill Grindability Test (Bond, 1952, 1961) gives the Bond Ball Mill Work Index. This Index expresses the resistance of a material to ball milling; the higher the value of the Bond Ball Mill Work Index, the more difficult it is to grind the material using a ball mill. This Index is widely used in the mineral industry for:

  • Effects of ball milling on the structure of cotton

    2019-1-17 · Then 5 g portions of the powder were placed in a locally built ball mill (Forziati et al. 1950) running at 1750 rpm. The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls 0.25 in. (~ 6 mm) in diameter were employed. This is considered to be a “vibratory” ball mill in contrast to the planetary type.

  • Bond Work Index an overview ScienceDirect Topics

    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
