After that, the crushed ore moves to the secondary crusher, which is usually a cone crusher. Here, it gets crushed even more, down to around 10-50 mm. Sometimes, they use a third crushing stage with a high-pressure grinding roll (HPGR). This can make the ore super fine, getting it down to 5-20 mm before it goes to the processing plant.
