Bond ball mill work index test standard pdf simulating.

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 2006this index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy.

A ball mill a type of grinder is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and paints ball mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium.

A bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits 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.

At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod millThe rod mill work index rwi is used for particle size determination in a size range from 25 mm down to 21 mm whereas ball mill work index bwi is used for the range from 2.
