The aggregate produced in a primary crusher is classified using a screen into a 0-20 mm fraction and typically a 20-150 mm fraction. The 0-20 mm fraction contains soil etc. and is generally considered to be of poor quality. This fraction is often used in road construction applications that feature low quality requirements. The 20-150 mm fraction is transported to the secondary crusher on

A good rule of thumb for equipment capacity in a primary crusher stage is therefore to aim at 70-75% capacity utilization. This will normally give enough margin to handle the given uncertainties in operating conditions. Another good rule of thumb for the design of jaw crusher stages is to start with the same setting on the grizzly separation and the jaw crusher CSS. This will often create good

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 large topsize acceptance was met with the UG design.
