125 mm grinding balls running 306 hours, with a 11.7% decrease in the grinding rate
Comparable media 41.9. μm/h, optimized medium 37.5 μm/h, with a reduced grinding rate of about 11.7%.
105 mm exercise ball improved compared to original medium 17%
18% Cr casting ball grinding is about 2% lower than the most recent competition; 105 mm exercise ball improves by about 17% relative to the original medium.
1,224 hours comparison for 8 media, 4 suppliers
90 mm, 15% Cr medium grinding rates were about 3.2% lower than those of another supplier; suppliers reported an overall cost improvement of about 16%.
18 month running data validation long-term stability
New high chromium media maintain mill stability, grinding performances comparable to the benchmark and provide a combined cost advantage reported by suppliers.
Stabilization media performance under high impact operating conditions
The hardness of the ore caused the ball breakage and the catch-up rhythm to be unstable.
Reduce grinding media consumption and stabilize the immersion of particles
The fine grinding phase of grinding media consumption is high, and particle-level fluctuations affect subsequent leaching efficiency.
non-spherical ball scats occupy effective SAG grinder volume
The removal of the bals scats is increased by more than 10%; only about 127.5 kg of the 2.5t sample was found to be effective grinding.
Make-up balls size change SAG fragmentation rate and projected throughput
The public summary shows that the simulation forecast 125 mm grining balls with SAG throughputs above 150 mm grining balls.
The condition for depletion is that the risk of grinding balls break-ups cannot be increased.
The grinding of grinding balls has been smoothly worn from about 4.5 inches to less than 1/2 inches, without deformation or fragmentation.
