The Bond Crushing Work Index (CWI) describes the competency of the ore at larger particle sizes. It is used for the calculation of the actual crusher power requirements. Pendulum mounted hammers with scale. -Test: At least 10 specimens preferably 20 specimens to be tested.

The measurements that are used in the calculation of the low-energy impact crushing work index are: the Joules of energy imparted by the hammers, the millimetres of width between the hammers at rest of the specimen being impacted, and the density of the specimen, per equation (1).

As a basic rule, impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chaer, keeping wear rates at a minimum, and producing high reduction ratios with a better-shaped end product.

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

Bond impact crushability work index (CWi) (Bond, 1963) results reported for iron ores vary from hard iron ore (17.7 kWh/t) to medium hardness iron ore (11.3 kWh/t) and friable iron ore (6.3 kWh/t) (Table 2.11; Clout et al., 2007).

Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.

1/12/2007· Bond (1947) defined the impact energy per unit of thickness C B by dividing the impact energy by the thickness of each particle w, so that (1) C B = 117 (1-cos ϕ) / w where ϕ is the angle, w is given in mm and C B in J/mm. From this and the material specific gravity ρ s (in g/cm 3) Bond proposed to estimate the crushing work index using the empirical relationship (2) Wi = 53.49 C B ρ s

As a kind of basic first rule you could say: Impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive material, which can be broken easily within the crushing chaer while keeping wear rates at a minimum and produce high reduction ratios with a better shaped end product.
