The crusher was born out of a need for a high capacity underground primary crusher that did not require a primary feeder, scalper, and the associated infrastructure therein. Minimizing the need for high cost stationary grids to control topsize underground was a requisite, and the topsize acceptance was met with the UG design.
The desired output size will impact the type of crusher you choose, as well as the capacity. For example, if you are looking for a small-capacity crusher, you will need to choose a different type of crusher than if you are looking for a large-capacity crusher.
