Bond Work Index (Energy equation) Grinding

BOND WORK INDEX The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore The Bond's Work Index equation is: W=WI* (10/√P80 10/√F80) where W= the energy input (Work input) per ton, kwh/metric ton WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore)Bond Index Of Grinding Bond work index tests grinding solutions ltdBond ball mill grindability test 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 stagecrushed to 100 passing size of 335 mm any screen size below 600m can be used for the testwork depending on your requirementsBond Index Of Grinding strandundbergdeThe 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 measured the Bond work index of three ore types using different test screen sizesBond Work Index an overview ScienceDirect Topics
