proper way to take axial samples in a Raw Mill
I am experiencing inaccuracies when taking axial samples (crash stop) of a raw mill. Whenever i take samples after the mill has cooled i noticed alot of the fines has settled to the bottom of the charge. Can anyone tell me a proper procedure to take axial samples in a raw mill or probably what am i doing wrong.

re proper way to take axial samples in a Raw Mill
Please see the attached pictures regarding correct way of axial sampling in a crash stop:
A few explanations:
- Need to dig 20 cm under the top material to take samples.
- Do this at three points on the width of the mill ( two samples from 0.5 m from sides of the mill and one from middle) and mix them before sieve analysis
- Use sieve to separate balls and material but retain material lamps in the sample
- Take the minimum sample weight mentioned in the graph
Let me know if you have any other questions.
