Bond ball mill index test jktech 20191114 a bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits sample requirements a minimum of 10 kg of material crushed to nominally minus 10 mm is preferred
Standard bond ball mill grindability test methodprocedure here is the old allischalmers bond work index grindability test procedure the standard feed is prepared by stage crushing to all passing a 6 mesh sieve but finer feed can be used when necessary it is screen analyzed and packed by shaking in a 1000cc graduated cylinder and the weight of 700 cc is placed in the mill and ground dry at 250

This knowledge is essential to define the required ball mill layout and production capacity in order to perform the bond index test successfully it is necessary to use precrushed sample material as defined below module ball mill minerals precrushed to 335 mm and sieved drillcore precrushed to 335 mm and sieved half drillcore pre
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 310 a question arises as to whether this practice will alter the ball mill work index bw i of the material
