SAG Circuit Design

Partial secondary crush circuits allow a stable load to develop and protect the liners. This is a good option for brownfields expansion targeting ~50% throughput increase. Partial secondary crushing also typically increases power efficiency. If the ore is really hard, you might just have to bite the bullet and go three stage crush ball mill.

How Ball Mill Ore Feed Size Affects Tonnage & Capacity

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

Understanding comminution: Compression versus impact crushing

Compared to compression crushing, impact crushing will create more fines within the circuit which will cause high wear if processing abrasive material. This is why rocks with lower silica content can be more suited for reduction by impact crushers. When compared to cones, impact crushers often have a lower capital cost, but can potentially ...
