Downpipe swivel sampler

Representative sampling even in confined spaces.

Taking bulk material samples over the entire chute cross-section for low installation heights.

Advantages of Downpipe swivel samplers

Single sample over the entire cross-section
Easy to integrate into systems via flanges
Low installation height
Sample spoon parks outside the product flow

Operating behavior & mechanical features

Representative sampling is carried out using a slotted vessel, which is swung through the material flow in a circular motion at a constant speed.

While the slotted vessel is rotated through the material flow, a sample is taken from the material flow and collected in the slotted vessel. This is then emptied by opening the movable base above the sample discharge chute. After complete emptying, the slotted vessel swivels back into the waiting position.

The waiting position of the slotted vessel is outside the main material flow in order to maintain the full chute cross-section and to protect the slotted vessel from permanent material impact.

The swivel movement of the slotted vessel can be carried out either by a pneumatic cylinder or by a three-phase motor.

Downpipe swivel sampler. Typical applications: Salt or electrical scrap processing

Drop tube swivel sampler Functional principle, the product flow is passed through the device and a representative sample is taken.

Removal of fine-grained, non-abrasive bulk material samples across the entire chute cross-section for low installation heights.

Piston sampler

Sampling from the falling product stream for fine-grained materials. Defined sample quantity for each extraction.

Screw Sampler

Sampling from the falling product stream for fine-grained materials. Variable sample quantity due to the duration of sampling.
