A crusher has a first crushing means (4) and a second crushing means (5) together with the first crushing means (4) defining a crushing grap (6). A measuring device (12. 13) 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 (11) is arranged to calculate a representative value that is representative of the highest, measured instantaneous load during each such period of time. A control device (11) is arranged to compare the representative value with a desired value and to control the load on the crusher depending on said comparison. In this type of control, a more efficient crushing and reduced risk of the crusher breaking down are obtained.
Cette invention concerne un concasseur comportant un premier dispositif de concassage (4) et un second dispositif de concassage (5) définissant entre eux un espace de concassage (6). Un dispositif de mesure (12, 13) sert à mesurer la charge instantanée s'exerçant sur le concasseur pendant au moins un laps de temps, le but étant d'obtenir un certain nombre de relevés. Un dispositif de calcul permet de déterminer une valeur qui est représentative de la charge instantanée mesurée la plus élevée pendant chaque laps de temps. Un dispositif de commande (11) est conçu pour comparer la valeur représentative à une valeur recherchée et pour doser la charge imposée au concasseur en fonction des résultats de ladite comparaison. Ce type de commande procure un concassage plus efficace et atténue les risques de panne du concasseur.
