Alsto Bond Index Ball Mill – Mineral Stats

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.

How Does Ball Mill Rotating Speed Influence Grinding

How Does Ball Mill Rotating Speed Influence Grinding

In ball mill, pulley and gear reduction mechanism is the key factors for cylinder rotating speed which is generally fixed. This speed will directly affect the grinding process. Ores and grinding media movement conditions will vary with the rotating speed. In grinding process, the grinding media and ores will go upward along the cylinder inner wall.
