Following a successful commissioning and start-up, we believe that two grinding lines at Las Bambas, PerĂº, each consisting of one SAG Mill and one Ball Mill (this mill combination is uniquely specific to Las Bambas ore types), are operating at design throughput of close to 140,000 tpd and within the range predicted by DJB from a managed multi-sample geometallurgical testing program (i.e., no pilot plant tests).
Your Project, whether small or large-scale, preliminary or more advanced, could benefit from our multi-discipline approach. Please contact us with your requirements at ddbarratt@uniserve.com.
Geo-Comminution SAG Mills, HPGR & Ball Mill Motors:
Matching Motor to Mill Operation
It is important to install sufficient motor power at its rated speed to cover the range of expected ore hardness vs mill throughput objectives. This chart shows that many SAG Mills are underpowered relative to possible maximum operating conditions.
