Open or Closed Circuit Crushing
The factors governing the determination of capacity for any open circuit crushing stage are much the same as those we outlined in connection with the secondary stage. In a properly designed crushing plant, excepting those plants which by-pass a portion of the pit-run around the head end of the flow line and inject this fraction back into the system at one of the reduction stages; the open
