Abstract
A crusher has first and second crushing elements spaced apart to form a crushing gap therebetween. A measuring device is arranged to measure the instantaneous load on the crusher during at least one period to obtain a number of measured values. A calculation device is arranged to calculate a representative load value that is representative of the highest, measured instantaneous load during each such period of time. A control device is arranged to compare the representative load value with a desired value and to control the load on the crusher depending on the comparison.
