Our philosophy is to first determine the variability of your ore using rigorous comminution testing, including Bond tests for ball and rod mills. We conduct a small number of expensive tests that require a larger sample size, such as the Bond Ball Mill Grindability Test. The results are used to calibrate a large number of less expensive tests ...

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.

SAG Mill Testing Test Procedures to Characterize Ore . The design of rod and ball mills is still carried out with the bond ball mill and rod mill grindability tests as discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill as such, primary ball mills should be designed with the rod mill work index, and single
• The Bond Ball Mill Grindability Test determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills The test is a closedcircuit, dry grindability test It is run in a standard ball mill and can be performed at mesh sizes ranging from 48 mesh to 400 mesh Bond Ball Mill …
The Bond_Mill Sizing spreadsheet was designed to determine the most appropriate mill dimensions and operating conditions for a given grinding task (known ore properties plus desired mill throughput and feed and product sizes), based on the traditional Bond's Law and the Hogg & Fuersteneau Power Model (see Mill Power_Ball Mills spreadsheet for further details on such model).
Aug 02, 2013 The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 . Based on his work, this formula can be derived for ball diameter sizing and selection: Dm = 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
