## Bond Impact Crushing Work Index -Procedure and Table of ...

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 …

## bond crushing work index 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.

## Bond Work Index Tests - Grinding Solutions Ltd

Bond Low Energy Impact Test. The Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizing crushers.

## Bond Tests | SGS

The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size. P80 = 25400 x Oss x ...

## Bond Work Index - an overview | ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...
