Example Embodiment

[0036] figure 1 The rotor 10 of an impact crusher is shown, which is used for crushing limestone, marl, clay, crushed stone or similar mineral materials. The rotor 10 includes a crushing roller body 12 having a substantially cylindrical shape, and the crushing roller body 12 has a central axial hole 14 to receive a shaft (not shown) for driving the crushing roller body. During the operation of the impact crusher, the rotor 10 rotates in the direction of the arrow, wherein the striking plate 18 is, for example, the other rotor rotating in the opposite direction ( figure 1 (Not shown in) or the striking plate 18 interacts with an impact element (not shown) arranged on the side of the rotor 10.

[0037] The crushing roller body 12 has six recesses 16 extending in the axial direction on its outer circumference, and wherein each of the six recesses 16 is provided with a striking plate 18 and a holding device 20. The substantially plate-shaped striking plate 18 extends over the entire ...

Abstract

The invention relates to a rotor (10) of an impact crusher, comprising a crushing roll body (12) and at least one holding device (20) attached to the crushing roll body (12) for holding a blow bar (18), wherein the holding device (20) has a guide frame (24) and at least one guide element (26), which is connected to the blow bar (18) and is movably attached to the guide frame (24) in such a way that movement of the guide element (26) in the radial direction in relation to the guide frame (24) results in movement of the blow bar (18) in the radial direction in relation to the crushing roll body(12), wherein the guide element (26) is arranged in such a way that the guide element can be moved in the axial direction in relation to the blow bar (18).

Description

technical field [0001] The invention relates to rotors for impact crushers Background technique [0002] Typically, impact crushers are used for crushing materials such as limestone, marl, clay, crushed stone or similar mineral materials. Known impact crushers have a rotor with evenly spaced strike plates. The rotor interacts with a second rotor rotating in the opposite direction or with impact elements arranged at the side of the rotor, for example to break up material. [0003] In the case of known impact crushers, the striking plates are each wedged, for example hydraulically, into a recess in the crushing roller body. The strike plates of such impact crushers are subject to severe wear and require regular maintenance. In the case of wear, the strike plate of known impact crushers is completely replaced or turned over, whereby the opposite end of the strike plate is also subject to wear. Such an impact crusher is known, for example, from DE3521588A1. [0004] Replaci...
