A horizontal shaft impact crusher (1) comprises a crusher housing (2), an impeller (4) mounted in the crusher housing (2), a curtain (28) against which material accelerated by the impeller (4) may be crushed, and an adjustment device (42) for adjusting the position of said curtain (28) relative to the impeller (4). The crusher housing (2) is provided with two guide rods (90) to which said adjustment device (42) is slidably connected. The adjustment device (42) is provided with a locking device (92) having a holding mode in which the locking device (92) is de-energized and arranged to hold said adjustment device (42) with a holding force in a crusher operation position relative to the guide rods (90), and an adjustment mode in which the locking device (92) is energized and arranged to release the holding force, thereby enabling displacement of the adjustment device (42) relative to the guide rods (90). |
