Crushing plant - Wikipedia
A Crushing plant is one-stop crushing installation, which can be used for rock crushing, garbage crushing, building materials crushing and other similar operations. Crushing plants may be either fixed or mobile. A crushing plant has different stations (primary, secondary, tertiary, ...) where different crushing, selection and transport cycles are done in order to obtain different stone sizes or the required granulometry.

Cycle Time Formula. Once the elements of the measurement are determined, the calculation is relatively straightforward. In this case, computing cycle time is the total production time divided by the units produced: Ct= Pt/Pu. Ct = Cycle time. Pt = Net production time. Pu = Units produced during net production time.
