Powder Sampling

CRP manufactures powder sampling systems using a thief to take the sample from the vessel or chute.
Commonly these sampling systems are used on filter dryers where the powder sample is taken across the top of the filter bed.
Generally the sampling systems fall into two types  whether they are used in a horizontal or vertical plane.

The SD VM 700 is designed to enter a vessel / filter dryer horizontally. The sample theif is closed whilst the sample probe is introduced, when the probe is fully extended into the vessel the thief is opened tanking a sample of the powder. Once the theif is full, it is closed once more and the probe withdrawn from the vessel, bearings and scrapers keep the probe free of powder. The vessel isolation valve is closed and finally the probe can be removed. The powder can then be dispensed into a bottle or bag.


SD VM 800 is designed to introduce a thief into the process vessel through a nozzle in the lid of a reactor, the probe is lowered down to the correct level in the vessel before the thief is opened and sample powder extracted from the process. The probe is then wound back and out of the vessel where the sample can be dispensed. To help specify a powder sampler please complete our design specification questionnaire that can be downloaded here.


   Various thief designs are available to suit the type of powder being sampled
