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.

There is also a JKTech Bond Ball Mill Work Index Light. Basically only does the BBMWI to 3 cycles instead of the steady state. Requires less material ie 3kg, costs less even if you do duplicates. Apparently based on their data base data they have an average error of 4% compared to 3.5% for the full BBMWI. Regards, Chris P Peter Amelunxen

This test determines the Bond Ball Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements for sizing ball mills. The test is a closed-circuit, dry grindability test is run in a standard ball mill, and can be performed at sizes ranging from 595 mm to 37 microns.
Correction of Bond Ball Mill Work Index Test for Closing Mesh Sizes It is commonly known that one must run the Bond ball mill work index test such you pick a closing mesh to give a P80 close to desired grind size.
For every bond ball mill work index test carried out at jktech a standard report is issued the report details the bond test procedure method and presents the results including f80 p80 grindability and work index further interpretation of the results is available if required frequently asked questions bond ball mill work index.
Siddall et al (1996) identified the ratio of Bond rod mill Work Index and ball mill Work Index as being indicative of an ore's compentency.

The test work program was carried out on those five ore samples obtained from the copper-porphyry orebodies. Total of 38 Bond work index tests, including duplicates, were done. Standard Bond ball mill test procedure were carried out on crushed (-3.35 mm / 6 mesh) material at different
In September 2021, the :Outotec Jar Mill arrived and was installed in the Institute TOMS laboratory. The Institute's comminution team was trained by M:O's specialists and the lab was granted accreditation to perform the Jar Mill testing.
the relative grindability of different ores in ball milling (Bond, 1961 and Rowland and Kjos, 1980) To use the Bond ball mill work index to determine the ball mill specific energy required for a particular grinding task, the Bond equation must be used and the various relevant efficiency factors applied. In

The computation of a Bond ball mill work index was empirically calibrated by Fred Bond using a short ton basis. The modern (metric tonne) basis is the following equation: NI43-101 reports often provide P 100 and the work index. To estimate the other parameters, you can assume: the P 80 is 0.92 × (P 100, µm)^0.96
The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to passing size of <3.35 mm.
