Slurry Stream Sample Cutter Dimensions for Grinding Circuit Survey

Slurry Stream Sample Cutter Dimensions for Grinding Circuit Survey

A good grinding circuit survey (and flotation circuit sampling) is only as good as the sample cutter used for each slurry stream.  Correct sampler volume and opening size insures your sample is representative of the concentrator stream you are testing.  Here is a good suggested design with opening dimensions.  You need to add the handle that matches your sample point location.

As opposed to the Outotec ultra expensive in-stream samplers show above, a Thief Sampler is the best budget alternative. It allows for the collection of samples in pump boxes, tanks and conditioners for samples such as:

  •  Final Tails
  •  Cu Ro Conditioner
  •  Primary Cyclone Overflow
  •  Pb/Pre-Flotation Tailing

The other streams would be best sampled/taken using a sampler as shown on the right but with a mouth wider than the diameter of the pipe it is sampling.
