1. A rock processing system including at least one rock processing apparatus for crushing and/or sorting granular mineral material according to size, the rock processing system comprising as system components:
a material feeding apparatus having a material buffer for loading starting material to be processed;
at least one working unit comprising at least one crushing apparatus and/or at least one screening apparatus;
at least one conveyor apparatus configured to convey material between system components;
at least two discharge conveyor apparatuses configured to convey processed material out of the rock processing system onto a stockpile, each of the at least two discharge conveyor apparatuses conveying processed material of a different value grain grading curve output by the at least one screening apparatus;
at least one quantity sensor for each of the at least two value grain grading curves, respectively configured to detect a quantity variable representing a discharge quantity of processed material accruing per unit of time in the respective value grain grading curve; and
a data memory connected in signal-transmitting fashion to a control unit and/or to the at least one quantity sensor;
wherein the control unit is configured to control an operation of at least one system component according to detection signals, which represent the discharge quantities accruing per unit of time in different value grain grading curves, and according to at least one data relationship stored in the data memory, which, by taking into consideration at least one predetermined target variable or at least one predetermined target variable range, sets the detection signals of the at least one quantity sensor and/or a value derived from the detection signals of the at least one quantity sensor quantitatively or qualitatively in relation to at least one control operating parameter and/or to at least one change of a control operating parameter of at least one system component.
