Screw sampler

A sampling screw (auger) rotates slowly (a few rpm's) and continuously extracts powder material from the sample process stream in a vertical or close to vertical chute section. A mixing tank – on the same axis as the screw – collects the material for a composite sample. The mixing tank has internal lifters rotating with the auger, which means that the sample material in the tank at all ...

Screw sampler Type SPN by SIEBTECHNIK TEMA

At the time of sampling, the screw-conveyor first of all empties the sample collecting pipe in the direction of the material flow. After a defined emptying time, the screw reverses and. conveys the sample material dropped into the sample collecting pipe to a pipe socket outside the principal pipe.


The immersion depth of the screw is adjusted between 200 mm and 300 mm depending on the cross-section of the production line to be sampled. Thanks to the openings in the sample collection tube, in which the screw runs, a representative cross-sectional sample of the free-falling particles is obtained.
