Regardless of whether the feed material has a Mohs’ hardness value of over 4, or is a soft material such as limestone, talc, or baryte — which would nevertheless cause a high degree of wear in high-speed mills because of hard and abrasive constitutents — Super-Orion ball mills ensure low-wear and cost-effective processing. We have continuously improved the ball mill over the years from a simple machine for the industrial minerals sector to a high-tech machine for the mineral powder industry. The original milling principle and the unparalleled robustness of the machine have not changed. Today, there are three different standard designs available.

Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving milling media — in this case, balls. The diameter of the balls is between one and several centimeters to suit the application — smaller balls for fine milling results and larger ones for coarser milling tasks. The drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed.
