Of the bond ball mill grindability test. for all model based methods a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. morrell (1996) proposed a mathematical model for autogenous semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

Jul 30, 2020 An improved method using less mass compared to the Bond Ball Mill Work Index test. The JK Bond Ball Mill (JKBBM) test, is a locked cycle grindability test conducted using a standard laboratory Bond Ball Mill with the same steel ball charge and material feed size (100% passing 3.35 mm) as the Bond Ball Mill Work Index test.
