[Get Info]1 Introduction A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO, 2006)This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill .

[Get Info]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 335 mm, as required for the Bond Ball Mill Work Index test feed

[Get Info]The work index covering grinding in tumbling mills of coarse sizes is labelled M ia The work index covering grinding of fine particles is labelled M ib (Morrell, 2008) M ia values are provided as a standard output from a SMC Test® (Morrell, 2004a) whilst M ib values can be determined using the data generated by a conventional Bond ball mill .
