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.

The role of the secondary crushing circuit, like every other stage in mineral processing flowsheets, is to prepare the feed material for the next stage of the process. The equipment selected depends on the characteristics of the ore and the desired end-product. However, in most mineral processing applications, the ore is relatively abrasive ...
