Vezin Sampler

The Vezin Sampler (VS) is designed to extract increments from a vertically falling stream of material. Representativity is ensured since a complete cross section of the free-falling bulk material is collected.

Variant 1 (standard): The Vezin Sampler Single (VS-S) has one cutter that extracts one representative increment per rotation.

Variant 2: The Vezin Sampler Dual (VS-D) has two opposing cutters which enables extractions of two representative increments per rotation.

The Vezin Sampler (VS) is:

• Well suited for relatively small volumes of bulk material in particular powdered material with lumps up to 40 mm.
• Highly accurate and robust.
• Easy to install and operate.
• Designed for primary, secondary, and tertiary cross-stream sampling of falling streams of material.
• Equipped with an easily accessible hatch for optimal inspection and maintenance process.

The VS is fully enclosed by a funnel-shaped housing which supports a gear motor driving a cutter rotating around a vertical axis. The cutter head is radially delineated with dimensions and working velocity designed to be individually optimized for each specific material. A hatch on the top of the VS allows for easy access for cleaning, maintenance, inspection, and exchange of cutter heads.

When triggered the VS extracts a representative increment per rotation which is guided directly into the sample outlet chute (oriented parallel to the main process discharge port) and continues to the next stage of the sampling process. Reject material passes directly through the VS. After each completed rotation, the cutter is parked in a safe position well away from the material flow (avoiding influx of extraneous material and cross contamination between samples). Acceleration and deceleration from the parking position takes place well outside the cutting zone, ensuring a constant operational cutter speed.
