    Procedure for determination of ball Bond work index in the

    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.

    Bond Work Index

    The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 336 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi) The work index calculations across a narrow size range are conducted using the appropriate laboratory work.
