How To Calculate Crusher Work Index
Crusher operating work index calculation sizing a crusher can be done reliably calculated thanks to the impactcrushing work index and the testwork research done by fred chester bond and his 1952 according to bonds third theory of comminution the workenergy input is proportional to the new crack tip length created during particle Crushing work index Calculation (4 replies) STAHI 6 years ago STAHI 6 years ago and the variation between the laboratory test and your observation of the operating crusher is within the normal range of variation for this calculation It appears normal to me this is a noisy test, unfortunatelyCrushing work index Calculation Crushing, Screening The rod mill work index is computed with an equation very similar to that of the crusher work index (CWI) or impact work of operating pressure and moisture In general, the impact or crushing work indices (CWi) calculated from test work crushing and other operating factors crusher operating work index calculation

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 2008/08/09The maximum operating work index was found to be almost three times larger than the minimum, and the final grinding step showed the highest operating work index Morrell (2004 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 Procedure and What is the Bond Work Index FormulaEquation? In case you had forgotten, here is a classic: You can read all the details of this now “Biblical” grinding power requirement calculation formula in Fred Bond’s original paper You can also review the stepbystep Bond Work Index Test Procedure I posted here See this useful summary Table of Bond Work Index by MineralsBond Work Index FormulaEquation 911 Metallurgist

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 The operating fi work index, though, is in the range of 21 kWh/t to 25 kWh/t showing high ineffi ciency This raises the point that, in some cases, the Bond EF4 oversize factor calculation is not suf cient to compensate fi for the milling inef ciencies that arise This can result in fi the mill being undersized To counter this problem it A Method of C alculating Autogenous/ SemiAutogenous bond work index calculation mill efficiency Bond Standard Circuit Work Index Assume the rod mill Work Index of 95 applies from theactual rod mill feed sizeof 19 300 mµalthough some of this work might ideally be doneby crushers to achieve a rod mill F80 of 16 000 mto a rod µ millcircuitproduct size ball mill bond work how to calculate mill bond or work index
