Definitions
- the invention relates to a method for sieving bulk goods and liquids, in particular also of powder coating particles, and a device for carrying them out of the procedure.
- the screening of bulk material is used to separate contaminants (Protective screening) and the separation of bulk material into fractions of a certain Particle size or a certain particle size range (classification).
- Bulk goods can be, for example, granules, powders and lacquers.
- the material to be sieved is in one Sieve hose and is pressed against the sieve fabric by a swirling movement.
- a swirling movement can smear especially with fine-grained material and thereby a Obstruction of the screening process occur.
- the screens used are, for example set in motion with electro-magnetic drives.
- the tumbler screens work with firmly clamped sieves, which over the Sieve frames need to be tensioned.
- DE-A-195 34 629 describes a vibrating screen in which a screen fabric rests on a sieve frame and only partially on it, namely on three sides, is fixed.
- spray booths are used for Powder coatings of workpieces described in which the cabin floor as Vibration sieve bottom is designed.
