Change of path

In bulk sampling, the term "path change" could refer to the change in the direction of movement of the bulk material during the sampling process. This change in path can be caused, for example, by special sampling equipment or techniques to take a representative sample.

Here are some possible contexts in which a path change might be relevant:

  1. Sampling point: The point at which the sample is taken could be chosen so that the bulk material has to undergo a path change, for example at a curve or a junction in the conveyor system. This can help to obtain a representative sample because the material is mixed more thoroughly and "channels" are less likely to form in which certain parts of the material are underrepresented.
  2. Sampling device: The sampling device itself could be designed to create a path change in the bulk material to obtain a representative sample. For example, rotating or oscillating sampling devices could be used to mix the material and take a representative cross-sectional sample over the entire width and depth of the bulk material flow.
  3. Sample preparation: After collection, the sample could undergo a path change, for example by a system that mixes, crushes or sieves the material to prepare it for analysis.

It should be noted that the exact context and meaning of the term "path change" may vary depending on the specific circumstances and requirements of the sampling process. When in doubt, it is always advisable to seek the advice of experts.
