• 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 test research done by Fred Chester Bond and his 1952 . According to Bond’s Third Theory of Comminution, the /energy input is proportional to the new crack tip length created during particle breakage and equivalent to the represented by the product the feed. A crude test

• Test: Bond crushing index SAGMILLING.COM

The Bond low-energy impact crushing index (more informally, the Bond crushing index) is not as common as the Bond ball mill 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 an overview ScienceDirect Topics

Calculations involving Bond’s index are generally divided into steps with a different Wi determination for each size class. The low energy crushing index oratory test is conducted on ore specimens larger than 50 mm, determining the crushing index (Wi C, CWi or IWi (impact index)).

• Bond Work Index Formula-Equation

Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the index, or the grinding resistance parameter. It represents the energy input required in kilowatt hours to reduce a short ton from theoret在911metallurgist上查看更多信息
