ABSTRACT:
In a method for the computer-based process control of a fragmentation apparatus having an energy storage device which is discharged via a spark gap to a load consisting of fragmentation goods submerged in a process liquid and disposed in a space between two electrodes which is filled with a process liquid, electrical operating parameters are determined during at least one discharge of the spark gap, whereby, in the space between the electrodes, a discharge channel is formed, and the point in time TDwhen such a discharge channel is formed and the electric resistance REof the discharge channel are used as control values for controlling the fragmentation apparatus.
