  • the screen means is designed in such a way that it allows a vacuum-driven, in particular lateral, passage of degraded blasting media, in particular component groups that have a specifically lower weight and / or smaller average size, into an adjoining, in particular essentially all-round, passage space, driven by a negative pressure means, and wherein a gravity-driven collection is set up in a collecting space for a returnable constituent group, including in particular reusable blasting media, in a lower region of the swirl space.
  • the invention enables a reliable and quick separation of component groups so that reuse is possible with regard to necessary recycling and an advantageous cost structure.
  • a mixed, contaminated air flow with dust / material air is separated through a sieve in a closed room, avoiding losses or external contamination.
  • the device offers a passive device with a space after a feed that is enlarged so that good turbulence and separation is given.
  • the device is compact with short distances, which leads to considerable energy savings. It can be used advantageously with regard to 3D powder bed dusts / waste, for metal dusts or plastic dusts, sandblasting waste, blasting powder waste, plastic, diamond powder and more.
  • advantageously degraded blasting material can be separated from sand with about 360-420 ⁇ m dust particles through a sieve with passage openings of about 100-200 ⁇ m, about 40% can be successfully sieved out.
  • Standard powder and degraded radiation media waste from 3D laser production can be cleaned and largely recycled through sieve openings of around 100-200 ⁇ m.
  • degraded blasting agent can be guided out of the passage space by means of an air flow generated by means of a negative pressure medium, in particular through ducts, to a collecting area. It is advantageous if reusable blasting media collected in the collecting space can be guided out as a returnable constituent group by means of a passed air flow, in particular through ducts to a collecting area, the collecting space arranged in the lower area in particular having an exit area for collected blasting media, which in particular can be closed and / or is to be opened, in particular by means of an adapted float, which is arranged in the collected blasting media.

  • the folding means driven by the air flow enable a continuous, safe cleaning effect.
  • the turbulence space together with the adjoining passage space is made larger than an inflow area, and / or the inflow area can be attached, in particular adjustable, at different angles with respect to the adjoining passage space. Due to the size ratio of the inflow area and passage space, an advantageous lowering of the speed can be undertaken, whereby an improved separation of particles in the air flow is possible, in particular through the sieve means.
  • the dust / material air flow can advantageously impinge on different areas of the passage space or be fed in another way, for example to an area in the curvature of the inflow area or an area directly on the sieve means, so that a Cleaning effect can take place through the impact and possibly vibration of the sieve medium by the dust / material air flow.
