  • Open or Closed Circuit Crushing 911 Metallurgist

      In a properly designed crushing plant, excepting those plants which bypass a portion of the pitrun around the head end of the flow line and inject this fraction back into the system at one of the reduction stages; the open circuit tonnages decrease from stage to stage, because fractions of the flow which are finer than the setting of each stage are scalped off

  • Circulating load calculation in mineral processing

      A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution

  • Closed Circuit Grinding VS Open Circuit Grinding

    Open Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating CostsClosed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill for further grinding In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier used to close the system This type of grinding is the most common circuit found in mineral processing facilities, mainly because a lot of ores and product require
