Laboratory studies and in-field observations shown that the charge decay characteristics of the granular materials at the surface of the grounded roll electrode significantly influence the outcome of the electrostatic separation process. An indirect method of charge decay characterization consists in the measurement of the electrical potential at the surface of single- or multi-layer of such materials. |
