allowing a greater volume of material to be processed in a 24-hour period. The downside to this is that the grind size of material sent to the Flotation plant has also increased.
The concentrator staff carried out a sampling campaign at the end of August 2013, by which time the mill speed had already been changed back to 68% critical. A further sampling campaign

Until 2010/11, Kroondal mine operated their primary mills at the KP1 concentrator as rod mills running at 68% of critical speed. The rod mills were subsequently converted into ball mills. At
seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t

If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum
to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage,
diameter, with lifting bars on the inside. The SAG mills are loaded with 105 millimetre forged steel balls, known as media, to facilitate the grinding, with the addition . teel balls and throw them
Each FOX Forged Steel grinding ball is solid from surface to center. These sturdy, well-built, shock-absorbing steel balls are the perfect hardness for ball mill grinding. Whether you are
A completely new concentrator has been built, which went into production in June 2011. Each Ball mill is also driven by two 8,500 horsepower ABB motors. Figure 3 - The 24’ x 39.5’ ball
