In this scientific study, the objective is to determine the bond work index of a given ore. a given ore was prepared by stage crushing and grinding, and underwent feed size analysis. after which, the ore was grinded in a ball mill until a 250 circulating load was achieved.

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.

Kinetic grinding test approach to estimate the ball mill work index 345 kinetic grinding exactly 700 cm3 of 100 passing 3.35 mm material from each sample was progressively grounded in periods of 0.33, 1, 2, 4, and 8 minutes. our experience has shown that the required number of revolutions to achieve the circulating load of 250.

Modeling the specific grinding energy and ball 21 conclusions continued in the present work, equations were also derived, giving: zthe ballmill power drawp as a function of its dimensions: internal mill diameter d and length l, zthe ballmill power drawp as a function of the feed d f (mm) and the product size d (mm), the bond work index w i (kwhshort ton) and the mill throughput.

Rod mill work index test for these purposes. chose a o closing screen for the ball mill test one (standard square root of 2 series) mesh size coarser than the plant ball mill circuit p80. if between standard mesh sizes, the finer of the chose two. results of bond ball mill tests conducted with closing.

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100 passing 3.36 mm (6 mesh) to product size in the range of 45150 m (325100 mesh), thus determining the ball mill work index (wi b or bwi). the work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest,.

The bond ball mill work index (bbwi) test is carried out in a standardised ball mill with a predefined media and ore charge. 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 3.35 mm.

The work index expresses the resistance of the material to grinding. it represents the kilowatt hours per tonne required to reduce the material from theoretically infinite feed size to 80 passing 100μm (wills and napierpercent munn, 2006). bond devised several methods for predicting ballmill and rodmill energy requirements and.
