MEI Blog: March 2019
Mar 10, 2019· By classifying by size-only, screens, compared to hydrocyclones, give a sharper separation with multidensity feeds and reduce overgrinding of the dense minerals. Corporation is the leader in this field and will be sponsoring an MEI Conference for the first time at Comminution '20 , so it was good to drop by their booth to meet the USA team.

tions used for grinding circuits, namely reverse circuits and direct circuits. In the first case, the new feed of the circuit is reported to the classification stage, whose coarse fraction feeds the mill, while the fines are sent to the circuit product flow. In the direct circuit, the new feed reports directly to the mill before classification.
