Screening of Fine Granular Material

This article describes screening of fine granular materials, including minerals. The first part of the study presents a description of screening and an analysis of resulting conclusions. The second part describes screens that have been developed in Lodz Technical University labs. From a number of screens only three have been chosen and described in this article. Additionally, results of some pilot-plant-scale tests involving these screens made at Lodz Technical University are discussed. Experimental tests covered first motion of the sieves, and then the process of screening on these sieves. Results are presented both in a graphic form as diagrams and in the analytical form as correlations.
