Abstract

An anti-spin assembly is arranged in a gyratory crusher. The anti-spin assembly includes an expandable braking receptacle, which is adapted to be expanded by way of a pressure medium. The braking receptacle is arranged in a space between a first surface formed on a part which rotates with the crushing head and a second surface formed on a non-rotary part which is connected to the frame bottom part. The braking receptacle is arranged, when expanding, to engage both the first and the second surface, thereby braking the rotation of the crushing head.
