Grinding Circuit Design for Adanac Moly sgs.comto grindability testing required for the design of a plant for Adanac Moly Corp. to include SAG and Ball milling. The hardness of each sample was measured in terms of SAG power index, SPI (for SAG grinding) and Bond Ball mill work index, BWi (for ball mill grinding). A further measure, the Minnovex crusher index, Ci was also measured for use inBond Rod Mill Work Index Equipment & Apparatus ReviewCommentary on the apparatus of the Bond rod mill Work Index by Alex Doll December, 2015 [email protected] The Bond "Third Theory" of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period when Bond (and his collaborators) were gathering the information to calibrate comminution models.
Ball MillsMill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hphr/t) from an empirical formula.Standard Bond Ball Mill Grindability Test MethodProcedureHere 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 per cent circulating load.

QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE Determination of the energy consumption for ore grinding in a Bond ball mill requires samples of standard size, because changes in the size of the samples cause the change of the Bond work index (Magdalinovic et al., 2012). Due to the Bond test complexity and length, as well as the possibility to make mistakes duringbond ball mill grindability test procedureBond Ball Mill Index Test JKTech. The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
