Ball Mills - Mineral Processing & Metallurgy
A ball mill efficiently operated performs a wide variety of services. In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the Steel-Head Ball or Rod Mill will take up to 2″ feed …
Iron Ore Crushing & Grinding Controls
Most of the rod mill – ball mill circuit controls in the Iron Ore Industry are patterned after a scheme developed by Erie Mining Company. This control is based upon the premise that constant volume, and structure of feed to the cyclone will result in a controlled sizing of the cyclone overflow by varying the density of the cyclone feed.
Ore Grinding Mills - Mineral Processing & Metallurgy
Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drum-type, or combination feeder at one end and is discharged from the opposite trunnion. Ball mills …

How to Measure the Impact Forces in Ball Mills
The ball was placed and recovered in the feed end of the mill where impact is known to be less severe. Analysis of ball movement in mills of various size and speed can use these rather basic data to estimate relative impact severity in other mills.
