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 Impact Crushing Work Index Testing Machine - Pendulum ...
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.
Bond Work Index - an overview ScienceDirect Topics
The most widely used parameter to measure ore hardness is the Bond work index Wi. Calculations involving Bond’s work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index Wi C, CWi or IWi impact work index .
Bond Index Formula For Jaw Crusher Grinding
Bond Work Index Crusher. Bond Work Index Formula-Equation Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack Energy The basic work index equation is:W = 10 Wi/ P – 10 Wi/ F 1 where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% ...
Bond Work Index Tests - Grinding Solutions Ltd
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 100% passing size of <3.35 mm. Any screen size below 600& 181;m can be used for the testwork depending on your requirements. Bond Rod Mill Grindability Test
