Alsto ball mill a complying machine with the appropriate barrel and ball charge. The Bond Index Ball Mill is supplied standard with a barrel and rotating yoke assembly and the electric motor drive; with a standalone bench, funnel and screen.
Internationally accepted mineral metallurgical standard test procedures to determine the physical properties of ores include the Bond ball mill work index. This is empirical index determined by closed circuit grindability tests developed by F.C.Bond in the mid 1930’s.
It requires a specific 305mm diameter x 305mm long (inside dimensions) horizontal axis ball mill without lifters operating at 70 rpm to perform grindabilities from 28 to 500 mesh.
