Bond rod mill grindability testhe test determines the bond rod mill work index which is used with bonds third theory of comminution to calculate net power requirements when sizing ball millsarious correction factors may have to be appliedhe test is a closedcircuit dry grindability test performed in a standard rod mill.
Our philosophy is to first determine the variability of your ore using rigorous comminution testing, including bond tests for ball and rod millse conduct a small number of expensive tests that require a larger sample size, such as the bond ball mill grindability test.
the ball mill also provides representative samples of ore suitable for further testing e studies of leaching and concentration of the orehe ball mill of the present invention will be referred to herein as a semiautogenous grinding sag mill, to distinguish over ball mills known in the artackground to the invention.
