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.Standard Bond Ball Mill Grindability Test Method,The Wi value from this equation should conform with the motor output power to an average overflow ball mill of 8 ft. interior diameter grinding wet in closed circuit. For dry grinding the work input should normally be multiplied by 1.30. However, ball coating and packing can increase the work input in dry grinding.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

Procedure for determination of ball Bond work index

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling.JKTech Laboratory Services,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.Procedure for determination of ball Bond work index,The work index (Wi) is calculated in a laboratory-scale ball mill with Bond equation. The Bond work index has been widely used in designing full-scale mills but the Bond test is rather complex, lengthy susceptible to procedural errors and this is why attempts have been made to abbreviate and simplify Bond test procedure (Weiss, 1985). 2.
