GrindingExpert™ isn't just about SAG mills. Our GrindingExpert™ solutions include ball mill strategies that achieve the target grind size while maximizing throughput, or when the circuit is SAG mill limited, achieve the finest grind size possible, thus increasing mineral liberation and recovery.
ArcelorMittal Kryvyi Rih ore beneficiation plant produces magnetite concentrate at 65% Fe and 8% SiO2, of which the D80 is approximately 44µm after three stages of grinding with ball mills .
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
Multotec offers hydrocyclone optimisation for maximum mineral processing efficiency . Hydrocyclones, used for classification in mineral processing, must be correctly maintained to ensure they operate at peak efficiency.
Mine-to-mill optimisation: effect of feed size on mill throughput No. 48 SRK Consulting's International Newsletter One of the most valuable aspects of blasting is the generation of very fine particles (e.g., smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.
HPGR are used in various configurations such as pre-grinding, hybrid grinding and finish grinding, among others [4]. This is mainly due to the comminution effect under the action of high-pressure ...
