Insmart bond’s ball-mill work index is a measure of the resistance of the material to grinding in a ball mill. this index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill.
Lab/pilot plant equipment bond ball mill. this 12” x 12” ball mill is universally used for grindability testing and determination of the bond work.
Mill. as such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. this is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (mcken, verret, & williams, 2006.
The 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. the test much achieve a.
The grinding jar for the bond index rod mill is 12″ x 24″ in size and has a wave-shaped design. at least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. the rod mill work index (rwi) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas ball mill work.
