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.

CHALLENGE

Field issues

Make-up balls do not match the size of ore grains, mills and shredding environments, which reduces the effective fragmentation capacity of the mill volume per unit.

SOLUTION

Optimization of programmes

Compares 125 mm with the fragmentation rate curve and simulated throughput under 150 mm grinding balls.

START WITH YOUR CONDITIONS

Validation of the programme with on-site data

Submitt ore data on ore type, mills and current media, and obtain recommendations for targeted analysis.
