"Gearless mill drives are the 'workhorses' for grinding operations which are at the heart of any mine. The six ABB GMDs at the world-class Panama Cobre project are extremely robust given demanding ambient conditions. As the ore extraction pace indicates they are maximising throughput," said Rene Chacon, project manager at ABB for Cobre Panama. "They allow operators to react to changes in ore ...

It is well known that when the mill isn't turning, the mine isn't earning, so it's essential that operators can predict and plan for maintenance schedules. During this downtime the relining must be completed as quickly as possible and, with significant human involvement, it is a high-risk exercise. Composites can help overcome many of these challenges, because they are up to 35%-45% ...

Comminution costs include power, grinding media and maintenance materials. These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the "efficiency" of a modest plant is improved by simplifying the comminution circuit and reducing labour requirements. Improving the grinding efficiency of the comminution circuit by 10% will improve plant ...
