Sampling

“I have to analyze 200 grams of product…but I have a boat of 50.000 tons of product…
How shall I proceed?”

This question is a good starting point to explain and study what the sampling operation is or has to be. This question is essential for two main reasons: it shows how difficult it is to obtain representative samples in their process or from a large quantity of product (boat, train, etc.) and it also shows how essential the sampling operation is for the product qualification (optimization of the production, of the mine or for the quality classification of a product).




Rotary cutter sampler :

Solution used to collect representative samples in a vertical chute. This equipment is made for products of high variability.

Linear cutter sampler :

Solution used to collect representative samples at the discharge of a belt conveyor. This equipment is made for products of high variability.

Linear bucket cutter sampler :
Solution used to collect representative samples at the discharge of a belt conveyor. This equipment is made for products of high variability, big particle sizes and very high flow rates.





Cross-belt sample-taker :

Solution used to collect a quantity of product on a belt conveyor. Easy to install, robust and does not require any conveying system modification.

Piston sample-taker :

Solution used to extract a quantity of product in a vertical flow with a piston.
 
Manual piston sample-taker Pneumatic piston sample-taker


Screw sample-taker :

Solution used to collect a quantity of product automatically in a vertical flow. A cleaning operation is made before each sampling with the sampler PREC 22. Furthermore, the PREC 100 has a variable pitch improving a better representativity of the sampling lot.

Sample-taker under screw conveyor :

Solution used to collect a quantity of product under a screw conveyor.

Rotating screw sample-taker :

Solution used to collect a quantity of product in a vertical flow. Mainly suited for granular products as the grain shape does not change.
