usual. These plants used small jaw crushers, screens and slewing stackers for stockpiling. With the growth in the gold industry and a move to contract crushing in the iron ore industry the demand for larger equipment grew. This has accelerated so that even modest-sized direct-shipping iron ore (DSO) projects are using mobile crushing plant

This measure suggests that a VSI can save 2–14% of the energy consumed in grinding, depending on the energy model used and the final product size. This estimate is in agreement with an energy saving of 11.8% observed in an iron ore application where VSI's were introduced as a crushing step preceding the grinding circuit.

The remaining demand is covered by the more expensive, but energy-dense, NMC 111 and NMC 532 used predominantly for home energy storage. The NMC variants transition towards NMC 622 and NMC 811 in a similar way to the market for EV batteries, albeit with a delay owing to the time needed for transfer of technology and sufficient reduction in prices.
