Bond Work Index an overview ScienceDirect Topics
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 µm (325100 mesh), thus determining the ball mill work index (WiB or BWi).

Procedure for determination of ball Bond work index in the
1/1/2009· In the determination of ball mill work index 15 kg of representative ore at 100% + 3.35 mm is crushed to 100% − 3.35 mm (Amtech, 2006). The first grinding test is started with an arbitrarily chosen number of mill revolutions. At the end of each grinding cycle, the entire product is discharged from the mill and is screened on a test sieve.

CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL
The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage the

bonds work index ball mill manufactuering design a
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
