Bond Impact Crushing Work Index -Procedure and Table of,

P80 = 25400 x Oss x (0.04Wi + 0.40) P80 = 25400 x Css x 7Ecc x (0.02Wi + 0.70) / (7Ecc – 2Css) Where Oss = Open-side setting in inches. Css = Closed-side settings in inches. Ecc = Eccentric throw in inches. P80 = Aperture through which 80% of the product willBond Work Index - an overview | ScienceDirect Topics,The Hardgrove index is determined using the ASTM method D 409–71. It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured ( w grams) and the index is defined as I = 13 + 6.93 w.Table of Bond Work Index by Minerals,This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ‘around the world sample’. You can find the SG of each mineral samples on the other table.
