  • the bucket is turned around its bucket rotation axis pivoted so that the crusher screen is aligned approximately parallel to the ground is.
  • the drive units for Drive the shafts are arranged on the side of the bucket. That for the drive units the required lateral construction volume is disadvantageous in operation Dead space. For example, when moving in with the bucket Sieve breaker in a silo or along a building wall the sieve material between the side wall of the bucket and the wall of the building cannot be detected. The housing of the drive units is also heavily worn and contaminated exposed. Among other things, this has the consequence that the fastening screws of the cover plates as a result of damage or soiling become unsolvable. It is then necessary to use the screws or detach the cover plates. The maintenance and inspection of the drive units is therefore considerably more difficult.
  • the object of the invention is based on this prior art based, a device for screening and / or crushing screen materials to create, the sieving success is improved with increased throughput and relieved of the disadvantageous properties described above is.
