Operating Behavior & Mechanical Characteristics
The screw sampler belongs to the samplers that remove a selective sample from the material flow. To be able to secure sufficient representativeness, the product flows to be sampled must be homogeneous in terms of the different grain sizes. Sampling is carried out by means of a sample collecting pipe protruding in the material flow.
This sample collecting pipe is provided with openings, into which the material can drop permanently. 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.
