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

2021-7-12 A Review of Alternative Procedures to the Bond Ball Mill Standard Grindability Metals ( IF 2.351) Pub Date : 2021-07-12, DOI: 10.3390/met11071114 Vladimir Nikolić, Gloria G. García, Alfredo L. Coello-Velázquez, Juan M. Menéndez-Aguado, Milan Trumić, Maja S. Trumić

The work performed included analysis of operating performance data from 49 mills and included extensive determinations of the Bond Abrasion Index for different ore types. For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250 is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling. This happens after 710 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to
