Bond Ball Mill Grindability Test. TheBond Ball Mill Work Index(BBWi)testis carried out in a standardisedball millwith a pre-defined media and ore charge. TheWorkIndex calculated from thetestingcan be used in the design and analysis ofball mill circuits. Thetestrequires a minimum of 10kg of sample that has been stage-crushed to 100% passing size of <3.35 mm.

Here is the oldAllis-Chalmers Bond WorkIndex Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load.

TheBond Ball Mill Work Indexis a measure of the resistance of the material to grinding in aball mill. It can be used to determine thegrinding powerrequired for a given throughput of material underball mill grinding conditions. It is a 'locked cycle'testconducted in closed circuit with a laboratory screen.

TheBond ball mill work indexis one of the most commonly usedgrindability testsin mining, and is often referred to as theBond work index. Thetestis a 'locked-cycle'testwhere ground product is removed fromtestcycles and replaced by fresh feed. Thetestmuch achieve a steady-state before completion.

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 45-150 µm (325-100 mesh), thus determining theball mill work index(Wi B or BWi).

Bond Rod Mill Grindability Test. Thetestdetermines theBond Rod Mill Work Indexwhich is used withBond’s Third Theory of Comminution to calculate net power requirements when sizingball mills*. Various correction factors may have to be applied. Thetestis a closed-circuit drygrindability testperformed in a standardrod mill.
