Fine Grinding - A Refresher - SAGMILLING.COM
The easiest way to construct a fine grinding model is using laboratory test results. The “signature plot” result of an Isamill™ laboratory test is already in the form of Equation (3) and can be used directly for modelling. The Levin test, performed using a dry Bond ball mill work index apparatus, also gives a result in the form of ...
