the Bond equation (1961). For every Bond Ball Mill Work Index test carried out at JKTech, a standard report is issued. The report details the Bond test procedure method, and presents the results including F80, P80, Grindability and Work Index. Further interpretation of the results is available if required.Bond Ball Mill Index Test JKTech,A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 10 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.Bond Work Index Procedure and Method,This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

The work index expresses the resistance of the material to grinding. It represents the kilowatt hours per tonne required to reduce the material fromPrediction of Bond's work index from field measurable rock,Dec 10, 2016· In general, Bond's work index is used to determine the grinding efficiency and also to calculate the power requirement. The process is very time consuming and it requires skilled labor and specialized mill. A systematic investigation was carried out to predict Bond's work index using simple field measurable properties of rocks.
