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.
Ore hardness values are provided by Colluasi''s block model which has autogenous (AG), semiautogenous (SAG) and ball mills behave, plus developments. units were the JK Tech dropweight test (NapierMunn et al.,. 1996), the SMC Test#174; (Morrell, 2004) and the Bond ball work index test (Bond...

Due semiautogenous grinding (SAG) mill feed hardness testing FIG 2 Comparison of JKDWT A*b values and corresponding A*b estimates
Bonds Work Index Ball Mill Inner Liners Design. Bonds Work Index Ball Mill Inner Liners Design. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits The test requires a minimum of 10kg of sample that has been stagecrushed to 100 passing size of lt335 mm Any screen size below 600181m can be used for the testwork depending on your requirements
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 mm, as required for the Bond Ball Mill Work Index test feed.
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
In conjunction with the Bond ball mill work index they can be used to accurately predict the overall specific energy requirements of circuits containing: AG and SAG mills, Ball mills, Rod mills, Crushers, High Pressure Grinding Rolls (HPGR).
Bond Ball Mill Work Indices. All JKTech Power data adjusted The testwork was conducted with 25 +4 mm and 8 +4 mm kimberlitic ores of varying Hicom mill''s response
Leading the world in ore hardness testing. The SMC Test#174; is the most widelyused comminution test in the world for AG amp; SAG Mills, HPGRs and Crushers. It is used to design comminution plants, optimize circuit performance, forecast throughput, reduce CO 2 emissions and cut energy costs.
SAG Mill. Grinding Solutions offers the following tests for SAG mill testing and/or sizing. JKTech Drop Weight. The JKTech DropWeight Test measures the breakage characteristics of an ore for five size fractions in the range of 13 to 63 mm, at various energy inputs ( to kWh/t).
