Problems solved by technology

If the holding area is too large, a significantly greater material fraction of the striker bars may not be used for contact with the material to be shredded
Low utilization is economically unfavorable

Embodiment Construction

[0044] figure 1 The rotor 1 of the impact crusher, which is not shown further, is shown. The rotor 1 has a horizontal rotor shaft 2 which is mounted in bearings 3 , 4 . The rotor shaft 2 extends horizontally between the bearings 3 , 4 . The rotor shaft is driven by a belt pulley 5 . Strike bars 6 are arranged distributed over the circumference on the rotor 1 . exist figure 1 The uppermost beating strip 6 in the drawing plane of , like all other beating strips 6 , extends parallel to the axis of rotation D of the rotor shaft 2 .

[0045] In the following description of the strike bar 6 reference is made to a Cartesian coordinate system. The origin of the coordinate system is located at the center of the strike bar 6 , that is to say at half the length (z axis), height (y axis) and width (x axis) of said strike bar 6 . With respect to the uppermost striker bar 6 in the plane of the drawing and perpendicularly to the axis of rotation D, the x-direction runs tangentially to ...

Abstract

The invention relates to a beater bar, wherein: a. the beater bar has, within a Cartesian coordinate system, a longitudinal axis along the z-direction; a vertical axis along the y-direction; and a transverse axis along the x-direction; b. the beater bar has two end side end faces on each of its longitudinal sides and has a holding area between the front side and the back side between the end faces, the holding areas are respectively bounded by two longitudinal strips, the longitudinal strips extend with respect to the end faces, the longitudinal strips are arranged in mirror symmetry about they-z plane and about the x-z plane; c. the longitudinal strips are trapezoidal in cross section, the longitudinal strips having a wide bottom edge on the beater bar and a narrower top edge spaced fromthe bottom edge and having an inner inclined side and an outer side, the sides extend between the bottom edge and the top edge, and the inner side edge extends at a side angle of 20 degrees to 27 degrees with respect to the x direction; and d. in the installation position, only the inner side can be supported into the beater bar receptacle on the rotor in order to transmit forces.

Description

technical field [0001] The invention relates to a striker bar for an impact crusher having the features of claim 1 and to a rotor with such a striker bar according to the features of claim 8 as well as to a 14. The impact crusher. Background technique [0002] Impact crushers are used for crushing mineral material (natural stone or recycled material) and for producing fine and coarse rock particles. In this case, the material is placed freely in the region of action of the striker bars of the rotor and is thrown centrifugally from there towards the impact plate. The material is broken at the impact plate. Beat bars are wear parts and must be replaced periodically. In reversible impact crushers, the direction of rotation of the rotor can be changed so that the front and back sides of the striker bars can be used alternately until the wear limit is reached. Next, the strike bar can be flipped about its own longitudinal axis. The not yet worn end region of the beating stri...
