Abstract

A rotor of an impact crusher may include a crushing roll body that can be rotated about a center line of the crushing roll body. The crushing roll body may include at least one radial recess. The rotor may further include at least one blow bar positioned in the recess of the crushing roll body. Still further, the rotor may include at least one chock positioned in the recess between the blow bar and the crushing roll body. The chock may have at least one receiving region, in which an application means for moving the chock in a radially-inward direction is positioned.

First claim

1 .- 12 . (canceled)

13 . A rotor of an impact crusher comprising:
a crushing roll body that is rotatable about a center line of the crushing roll body, wherein the crushing roll body includes a radial recess; a blow bar disposed in the radial recess of the crushing roll body; and a chock disposed in the recess between the blow bar and the crushing roll body, wherein the chock includes a receiving region in which an application means for moving the chock in a radially-inward direction is disposed, wherein the application means is configured such that when the application means is moved in an axial direction along the chock the application means applies a radially-inward force to the chock.

14 . The rotor of claim 13 wherein the application means is at least partially wedge shaped.

15 . The rotor of claim 13 wherein the receiving region extends in the axial direction along the chock.

16 . The rotor of claim 13 wherein the application means extends in the axial direction.

17 . The rotor of claim 13 wherein the application means rests against the crushing roll body and the chock.

18 . The rotor of claim 13 wherein the receiving region includes a contact surface against which the application means rests, wherein the contact surface forms an angle of 5°-10° with respect to the axial direction.

19 . The rotor of claim 13 wherein the receiving region includes a contact surface against which the application means rests, wherein the contact surface forms an angle of 5°-20° with respect to the axial direction.

20 . The rotor of claim 19 wherein the receiving region on the chock comprises a projection on which the contact surface is disposed.

21 . The rotor of claim 13 wherein the chock has a wedge angle in a range of 5° to 30°.

22 . The rotor of claim 13 wherein the chock has a wedge angle in a range of 10° to 20°.

23 . The rotor of claim 13 further comprising an actuating element for moving the application means in the axial direction, the actuating element being mounted on the application means.

24 . The rotor of claim 13 wherein the actuating element is of a mechanical design, an electrical design, or a hydraulic design.

25 . The rotor of claim 13 wherein the blow bar comprises a trapezoidal recess and the crushing roll body comprises a trapezoidal projection that rests at least partially in the trapezoidal recess of the blow bar.

26 . The rotor of claim 13 wherein the blow bar comprises a recess and the crushing roll body comprises a projection that rests at least partially in the recess of the blow bar.

27 . The rotor of claim 26 further comprising a supporting device that has a support bar and is disposed in the recess of the blow bar adjacent to the projection to fix the blow bar in a radial direction.
