Embodiment Construction

[0036] figure 1 Shown is a rotor 10 of an impact crusher for crushing limestone, marl, clay, crushed stone or similar mineral material. The rotor 10 comprises a generally cylindrical crushing roll body 12 having a central axial bore 14 to receive a shaft (not shown) for driving the crushing roll body. During operation of the impact crusher, the rotor 10 rotates in the direction of the arrow, wherein the striking plate 18, for example, rotates in the opposite direction with another rotor ( figure 1 (not shown) or the striking plate 18 interacts with a striking element (not shown) arranged on the side of the rotor 10 .

[0037] The crushing roller body 12 has on its outer circumference six recesses 16 extending in the axial direction, and wherein a striking plate 18 and a holding device 20 are arranged in each of the six recesses 16 . The substantially plate-shaped striker plates 18 extend over the entire length of the crushing roll body 12 in the axial direction, so that the ...

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...
