A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s) Sample Requirements A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred JKTech would stage crush the sample to minus 3 35 mm as required for the Bond Ball Mill Work get price
The test work program was carried out on those five ore samples obtained from the copperporphyry orebodies. Total of 38 Bond work index tests, including duplicates, were done. Standard Bond ball mill test procedure were carried out on crushed ( mm / 6 mesh) material at different
CORRELATION BETWEEN BOND WORK INDEX AND The Bond''s standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 #181;m.
standard Bond crushing, and rod mill work indices, abrasion indices and by Dawson for Bond Ball Mill Work Index tests using crushed feed, and Standard Autogenous Grinding Design (SAGDesign) Tests, patented by Outokumpu. (See reference 8 below). The comparison of these results gives context to how the various measurements relate to each
ball mill grindability. The test mesh used was 100 mesh P gt; 1416 ]. The Bond work index W i was calculated from Equation (2) W i = /(P 1) X (Gbp) [10/(P 80) 0,5 #177; 10/(F 80) ] (2) Where: F 80 is the size in (#181;m), at which 80 percent of the new feed to ball mill passes,

laboratory tests, typically Bond ball mill Work Index and SMC test#174; / JKDWT A*b (Bond, 1961; Morrell, 2004). Due to budgetary constraints, this has curtailed the collection of suf cient number of BMWi or A*b measurements to allow the inherent variability to be adequately quanti ed for direct
micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is mm.
