ABSTRACT:
The object of the invention is a cone crusher comprising a shaft mounted in a frame for oscillating movement, and a rotor which is rotatably mounted on the shaft and adapted to be rotated on the shaft by means of a drive and which has an out-of-balance weight so that the rotation of the rotor in conjunction with centrifugal force sets the shaft in gyratory oscillating motion, while a conical crusher head carried by the shaft is caused to roll on the inner side of a crushing mantle carried by the frame. Characteristic of the invention is that the cone crusher is equipped with a movable counterweight which is caused by the drive to perform a circular movement about the shaft at an angular displacement of substantially 180.degree. relative to the movement of the eccentrically located point of gravity of the rotor, whereby the counterweight substantially contributes to stabilizing the frame in that the centrifugal force acting upon the frame actuates the frame substantially in phase opposition to radial forces which are transmitted to the frame from the rotor and the out-of-balance weight thereof via the shaft, the bearing points of the shaft and the crusher head.
