## 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 represented by the product – the feed. A crude test ...

## Testwork: Bond crushing work index - SAGMILLING.COM

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. Typically twenty specimens are chosen to represent a sample and the ...

The Bond crushing (impact) work index (Wi C, CWi, LEIT or IWi) conducted on specimens of a nominal dimension between 50 mm and 75 mm. The product size is not relevant to this test; it is a determination of the energy to the “first fracture” that substantially breaks the rock. A fourth index attributed to Bond is the abrasion index (Ai) which is used to predict the quantity of liner and ...
