The invention relates to a crusher (10), in particular a rock crusher, having a crusher unit (40), to which a band conveyor unit (60) having an endlessly circulating band conveyor is indirectly or directly assigned, wherein a magnetic separator (70) having a magnet (79) is held in the area of the band conveyor unit (60) above the band conveyor in the direction opposite from the direction of gravity,



and wherein an adjustment unit (80) is provided, which can be used to change the height of the magnet (79) above the band conveyor. To enable the reliable operation of such a crusher, it is provided according to the invention that the magnetic separator (70) is suspended from at least two limp ties (81, 82, 84, 85), and that the limp ties (81, 82, 84, 85) can be adjusted by means of at least one actuator unit (90) to change the height of the magnet (79).
