Crushing machine construction kit for the construction of a crushing machine, method for converting a rotary shear, and a method for converting a rotary shredder

1. A crushing machine construction kit for constructing a crushing machine, the crushing machine construction kit comprising:

a drive device;

a frame of a crushing device, said frame having at least a first side wall, a second side wall, a first end wall and a second end wall;

at least two shear shafts;

at least two shredder shafts;

said first end wall and said second end wall of said frame having bearing supports for a rotatable reception of, selectively, said at least two shear shafts or said at least two shredder shafts for a selective configuration of the crushing machine as a rotary shear or as a rotary shredder;

said bearing support having a basic element, a bearing support bridge, a pivot bearing and a releasable fixing device; and

rapid-change couplings providing a connection between said drive device and said shafts.

2. The crushing machine construction kit according to claim 1 , further comprising scrapers, wherein the crushing device, in a working mode as a rotary shear, is equipped with said scrapers.

3. The crushing machine construction kit according to claim 2 , wherein each of said shear shafts has a shaft, a number of shear disks and a number of distancing bushes, said distancing bushes form distancing spaces between said shear disks.

4. The crushing machine construction kit according to claim 3 , wherein in a working mode as the rotary shear, said scrapers are disposed along said first side wall and said scrapers are disposed along said second side wall, said scrapers protrude perpendicularly from said first and second side walls into said frame, said scrapers project at least sectionally into interspaces between said shear disks of said shear shafts including a first shear shaft and a second shear shaft, wherein a gap between said shear disk of said first shear shaft and said shear disk of said second shear shaft measures between 10 and 200 μm.

5. The crushing machine construction kit according to claim 1 , further comprising compression blocks, wherein the crushing device, in a working mode as a rotary shredder, is equipped with said compression blocks.

6. The crushing machine construction kit according to claim 5 , wherein each of said shredder shafts has a shaft, a number of shredder disks and a number of distancing bushes, said distancing bushes form distancing spaces between said shredder disks.

7. The crushing machine construction kit according to claim 6 , wherein in the working mode as the rotary shredder, said compression blocks are disposed along said first side wall and said compression blocks are disposed along said second side wall, said compression blocks protrude perpendicularly from said first and second side walls into said frame, said compression blocks project at least sectionally into interspaces between said shredder disks of shredder shafts, wherein a gap between said shredder disk and said compression block measures between 1 and 200 mm.

8. The crushing machine construction kit according to claim 5 , further comprising compression block bridges, wherein the crushing device, in a working mode as a rotary shredder, is equipped with said compression block bridges, said compression block bridges respectively connect two opposite-situated ones of said compression blocks.

9. The crushing machine construction kit according to claim 2 , wherein said frame is a rectangularly shaped frame.
