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.
2020-3-22The Bond ball mill work index is one of the most commonly used grindability tests in mining and is often referred to as the Bond work index.. The test is a locked-cycle test where ground product is removed from test cycles and replaced by fresh feed.
Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index and the Bond rod mill work index. These are empirical indices determined by close circuit grindability tests developed by F.C.Bond in the mid 1930s.

1999-6-4form the first bond ball bond. The capillary is then raised and repositioned over the second bond site on the substrate a precisely shaped wire connection called a wire loop is thus created as the wire goes. Deforming the wire against the bonding pad makes the second bond wedge bond or stitch bond.
