An important potash producer in Europe uses this simple, useful unit for sampling the pulp in their thickeners. It is particularly applicable to any potash operation and its low cost will appeal to many other plants where thickener density must be sampled.
The unit is operated manually and the depth from which the sample is taken is shown on a depth indicator. Suction on the discharge line draws thickener contents into the tube.
When the sampling pipe is depressed into the thickened pulp zone the thickened pulp is immediately visible in the glass and the depth of the top level of this zone is read from the quadrant type depth indicator.
