[email protected]Bonds Work Index Ball Mills Insmart Systems The bonds ballmill work index is a measure of the resistance of the material to grinding in a ball mill this index is widely used in the industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill scaleup utility this index is widely used in the mineral industry for Bond Work Index An Overview Sciencedirect Topics The ability to simulate thebond work indextest also allows examination of truncatedball millfeed size distributions on thework index for grinding circuits where the feed to aball millis sent directly to the classifier and the cyclone underflow feeds theball millsee figure 310 a question arises as to whether this practice will alter theball mill work indexbw i of the material Grindability Of Mixtures Of Cement Clinker Andtrass Nov 01 1998 the bond grindability tests were performed with the 6 mesh dry feed materials in a standard ball mill 305 305 cm following a standard procedural outline described in the literature the packed bulk densities of the bond test feeds for clinker and trass were 144 and 164 gcm 3 respectively work indices were determined at a test size of 200 mesh 74 m Process Ballcharge Clinkercement Clinkercement The most commonly employed formula was developed bybondand is as follows max 2017 x x 1 where example max biggestballdiameter mm d20 sieve dimension where 20 is retained m 15000 r specific mass of material grams cm3 309 wi bond work index kwh short ton 1349 du useful insidemilldiameter m 35 y Bond Indexfor Verticalmillgrinding Provesprojektde Bond index ball millrodmillbt 100 xl retsch the grinding jar for thebond indexrodmillis x in size and has a waveshaped design at least to kg sample material is required to simulate a closed grinding circuit in aballor rodmillthe rodmill work indexrwi is used for particle size determination in a size range from mm down to mm whereasball mill work
