Comments on taking a representative split
|
Taking a representative split from a large sample is not as simple as many people believe. Rolling on a mat, multiple grabs or riffle splitting do not produce accurate results. A classic study* conducted at Bradford University demonstrated that a rotating sample divider provided the best results.
* Critical evaluation of powder sample procedures. Allen T and Khan A. A, The chemical Engineer, May 1979, pp108 - 112 |
