bond crushing work. The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test.. The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.

11 Crushing and classification. 11 Crushing and classification Estimates vary, but it is generally accepted that of all the energy used in the World something like between 1 and 10% is in comminution, i.e. the processes of crushing, grinding, milling, micronising, etc. Changing the size of the particles by crushing creates many important industrial products.

The Bond Work Index is material specific and is obtained from laboratory crushing tests on the feed material. Hard and brittle materials have a work index in the range 4 × 10 4 − 8 × 10 4 J/kg. Bond's law holds reasonably well for a variety of materials undergoing coarse, medium and fine size reduction. (Eq. 14.3a) can also be reduced to

Based on Bonds Crushing Law the power required Based on Bonds Crushing Law, the power required to crush a certain material will change by if the diameter of the product is made smaller by 50. In crushing a certain ore, the feed is such 80 is less than 50.8 mm in size and the product size is such that 80 is less than 6.35 mm.

The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined 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 stage-crushed to passing size of <3.35 mm.
