Abstract: The invention relates to a crusher unit (10), in particular an impact crusher, having an impact rotor (11), having at least one swivel-mounted impact rocker (20), wherein a crushing gap (15) is formed between the impact rotor (11) and the impact rocker (20), wherein the impact rocker (20) can be swiveled along an adjustment path by means of at least one gap-adjusting means (30) to set a gap width of the crushing gap (15), wherein the impact rocker (20) is mounted such that its weight force acts in the direction of a reduction of the crushing gap (15). For a high degree of operational safety, the crushing gap can be readjusted during operation in that at least one retaining device (50) is provided, which uses a retaining force to flexibly counteract a swiveling of the impact rocker (20) in the direction of the impact rotor (11). The invention also relates to a method for setting the crushing gap (15) of a crusher unit (10).

Abstract: An impact crusher for mineral material includes a crusher housing, a reversible rotor arranged in an impact-grinding space of an impact mechanism for propelling mineral material against wear members in the crusher housing; and an adjustment installation setting a spacing of the impact mechanism from the rotor. An upper impact space adjoins the impact-grinding space at the top and has an entry opening for the mineral material. The upper impact space has an upper height region that neighbors the entry opening, a central height region that adjoins the upper height region, and a lower height region that is contiguous to the lower impact-grinding space, with the central height region being a region having a largest internal width and at a widest location thereof, which is above a crushing circle of the rotor, has a maximum width which is larger than a diameter of the crushing circle of the rotor.

Abstract: The impact shield (9, 10) carries a plurality of armor bodies (16) of a strongly wear resisting material. The armor bodies (16) are fixed horizontally in succession on a front side of the impact shield by a fixing element making it possible to detach them from the impact shield (9, 10) for their replacement. The impact shield (9, 10) is composed of a fixed part (21) connected to the frame (2), and a removable part (22) carrying the armor bodies (16) and making it possible to remove simultaneously all the armor bodies, fixed on the same, out of the grinding chamber (3). At least one such impact shield (9, 10) is arranged in a grinding chamber (3) of an impact grinding mill including a frame (2) further including a horizontal-axis rotor (6) provided with impactors (7) arranged regularly around its periphery.

Abstract: The mill includes a milling chamber (1) containing a rotor (2) provided with hammers (4), and at least one impact screen mounted pivotably with the aid of an adjusting jack in order to move the bottom end of the screen toward or away from the rotor so as to define, between the bottom end of the screen and the free end of the hammers, a spacing which determines a given particle size. The mill includes a device for positioning the rotor that includes indexing elements for positioning the end of one of the hammers as close as possible to the screen for adjusting the spacing. It includes a geared motor driving a pinion capable of engaging with a toothed wheel fixed in rotation to the rotor so as to rotate it from a rest state until one of the hammers is as close as possible to the screen.

Abstract: A horizontal shaft impact crusher, including a crusher housing having an inlet for material to be crushed and an outlet for material that has been crushed. An impeller is mounted on a horizontal shaft in the crusher housing and is operative for rotating around a horizontal axis. Material to be crushed is accelerated by the impeller against a curtain. An adjustment device is provided for adjusting the position of the curtain relative to the impeller. The crusher housing includes at least two guide rails to which the adjustment device is slidably connected. A retaining device is arranged to hold, with a predetermined holding force, the adjustment device in a crusher operation position relative to the guide rails. The adjustment device is movable along the guide rails from the crusher operation position and away from the impeller in response to an excessive force being transferred from the curtain to the adjustment device and exceeding the predetermined holding force.

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.
