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 3.35 mm, as required for the bond ball mill work index test feed.
The Bond work index estimated using the Bond's law and grinding specific energy consumption (39 kWh/t) was 22.4 kWh/t. This value is close to that obtained from a standard Bond-work index test for a SCBA with low quartz and carbon SCBA, which was 22.0 kWh/t . The difference, in this case, was only 1.8% for both calculated and experimental work ...

Testwork: Bond ball mill work index - SMILLING. 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.
others in Allis-Chalmers have developed a grinding test in a ball mill in a closed cycle until the establishment of stable recirculating load (Maxson et al., 1933). The Bond work index is a parameter which represents a measure of an ore resistance to grinding. Numerically, the work index represents the energy (kWh/sht)
