ThisGrindability Test or Bond Ball Mill Work Index Procedureis used to determine theBond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

The standardbond ball millworkindextest procedure is firstly to stage crush the feed to minus 335mm and size a representative sample the test then involves a series of batch grinds in a standardbond millabond millis 0305m by 0305m with rounded corners a smooth lining and runs at 70rpm the charge consists of 285 balls weighing a.
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 of45-150 µm(325-100 mesh), thus determining the ball mill work index (WiB or BWi).

TheBond ball millworkindexis one of the most commonly used grindability tests in mining, and is often referred to as theBondworkindex. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a steady-state before completion.
When F is the size in microns which 30 per cent of the new ball mill feed passes, P is the microns which 80 per cent of the last cycle sieve undersize product passes, and P1 is the opening in microns of the sieve size tested, then ball mill work index Wi is calculated from the following revised (1960) equation:

ABond Ball MillWorkIndexmay also be used in the simulation and optimisation of existingmill(s) and the associated grinding circuit(s). 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 3.35 mm, as required for theBond Ball MillWorkIndextest feed.
