Comminution testing - JKTech - University of Queensland

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 8 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.

Mills | Tüfekçioğlu

The mills should be filled with a suitable weight of rod or ball to benefit from most of the motor power. Filling ratios are generally 30-35% of the mill volume in rod mills and 40-45% in ball mills. Especially after rod charge, the charge swells up to 45% due to the coarse grain size (~25 mm) of the ore between the rods.

Bond Work Index - an overview | ScienceDirect Topics

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5 ). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
