The invention relates to a method for setting an operating state of at least one mobile mineral machining plant, in particular a mobile mineral material crusher (10), wherein a processing device (100) is provided, to which an input unit (90) is assigned, wherein at least one characteristic material value of the feed material (KM) to be machined is entered into the input unit (90), wherein at least one characteristic material value (KE) of at least one end material to be produced using the mineral machining plant is entered into the input unit (90), wherein a target machine parameter (SP) or a target machine parameter set containing several target machine parameters (SP) is generated in the processing device (100), taking into account the characteristic material value of the feed material (KM) to be machined and the characteristic material value of the end material (KE) to be produced, and wherein the at least one target machine parameter (SP) or the target machine parameter set is transferred to a control device (130) of the mineral machining plant and/or displayed on a display device. Such a process significantly facilitates adapting the mineral machining plant to changing crushing tasks for a machine operator.
