Abstract: A horizontal shaft impact crusher includes a crusher housing having an inlet for material to be crushed and an outlet for material that has been crushed. An impeller is mounted in the crusher housing for rotation about a horizontal axis. A curtain disposed in the crusher housing is arranged so material accelerated by the impeller is crushed thereagainst. An adjustment device, which adjusts the position of the curtain relative to the impeller, is slidable connected to guide rods. The adjustment device includes a locking device positionable selectively in either a holding state in which the locking device is de-energized and arranged to apply a holding force for holding the adjustment device in a crusher operation position relative to the guide rods, or an adjustment state in which the locking device is energized and arranged to release the holding force, thereby enabling displacement of the adjustment device relative to the guide rods.

Abstract: A horizontal shaft impact crusher includes a housing, an impeller, and a first and a second curtain against which material accelerated by the impeller may be crushed, the second curtain being located downstream of the first curtain. The housing is provided with a first and a second pivot point for mounting a first end of the first curtain in two different positions relative to the impeller, a first adjustment device for mounting a second end of the first curtain, a third and a fourth pivot point for mounting a first end of the second curtain in two different positions relative to the impeller, and a second adjustment device for mounting a second end of the second curtain.
