The Bond ball mill grindability test is run in a laboratory until a circulating load of 250 is developed It provides the Bond Ball Mill Work Index which expresses the resistance of material to More Bond Abrasion Index Mill Ellulnl Ball Mill Abrasion Index Sgs minerals services T3 sgs 138118 Мб
Bond Abrasion index Grinding Classification Circuits The d80 of ore reached to 480 μm in all samples to prepare materials for ball mill grinding experiments because d80 of plant ball mill feed in Sungun plant was 480 μm As a base for this study standard Bond grindability tests were initially done and Bond work index Wi values were calculated for
A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits 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 335 mm as required for the Bond Ball Mill Work Index test feed
