LMVS Vezin Sampler
Universal, high performance Vezin Sampler for sampling inline from a continuous stream
The Vezin Sampler can be used for primary or secondary sampling. It is a fully enclosed unit containing a rotating sample cutter that passes at constant speed through the falling stream of slurry or free flowing solids entering it.
The machine needs to be placed within an existing or new to build installation for in-line sampling. With the use of an axle, driven by an electrical motor, the spoon is moved through the product stream collecting the required sampling amount. The frequency of the spoon can be controlled by the control box.
Often used in combination with a Sample Collector.
The Vezin sampler is an efficient and reliable mechanical sampling device designed to extract accurate, representative samples from bulk material streams in industries like mining, mineral processing, and bulk handling.
Its rotating cutter ensures proportional sampling across the entire material flow, while its ability to handle a wide variety of materials, from coarse ores to fine powders and slurries, makes it versatile for numerous applications.
With benefits such as consistent sampling, low maintenance, and adaptability to automation, the Vezin sampler plays a crucial role in quality control, metallurgical accounting, and process optimization.

working principle Vezin Sampler
The Vezin sampler is a highly reliable mechanical sampling device designed to extract accurate and representative samples from bulk materials in continuous flow.
Widely used in mining, mineral processing, cement production, and bulk material handling, it ensures consistent sampling for quality control, analysis, and process optimization.
At the heart of the Vezin sampler is a rotating cutter that slices through a free-falling or flowing stream of material—either dry bulk or slurry.
As the cutter rotates at a controlled, adjustable speed, it captures proportional segments of the material stream at regular intervals. This method ensures the sample reflects the true composition of the entire flow, including variations in particle size, density, and distribution.
Typically installed in chutes, conveyor lines, or pipelines, the Vezin sampler can handle a wide range of materials, from coarse ores to fine powders and slurries.
Collected samples are directed through one or more ports to containers or further sample preparation equipment, while the bulk material continues uninterrupted along its path.
The rotation speed of the cutter can be fine-tuned to match varying flow rates and material types, ensuring accurate sampling under changing process conditions.
Enclosed and sealed, the sampler prevents contamination and guarantees clean, uncontaminated samples—crucial for high-value or fine material applications.
How it works
Installed in a chute or sampling station, the LMVS cuts through the free-falling stream at constant speed. Sampling frequency and rotation speed are set via the control box/panel, and collected increments discharge to a sample container or sample collector for downstream preparation.
Vezin Sampler control panel
Our Vezin sampler control panel offers precise and reliable control of the sampling process, ensuring accurate and consistent results.
Designed for seamless integration with automated sampling systems, the panel allows easy adjustment of cutter rotation speed, cycle timing, and sampling intervals.
A user-friendly interface and built-in safety features make operation straightforward and secure.
The control panel can also be linked to centralized plant systems for real-time monitoring.
Engineered for durability, it performs dependably even in the toughest industrial conditions, making it an essential component in any high-performance sample preparation setup.
Vezin Sampler Project integration
Vezin samplers can be easily integrated into automated sampling systems, allowing for continuous sampling without manual intervention.
This increases operational efficiency and reduces the need for personnel to be involved in the sampling process, especially in hazardous or difficult-to-access locations.
