 Hydrocyclones for Closed Circuit GrindingReduction of mill load by combining mill with hydrocyclones. Open circuit: The hydrocyclone deslimes the feed before being fed to the mill, e.g. < 63 µm. Closed circuit: Degritting of mill discharge and re-circulation to the mill feed. Herewith preventing "dead" grinding, resulting in a smaller grain size spectrum and shortening the duration of milling (optimum use of the mill). Double circuit: The hydrocyclone deslimes the feed and simultaneously reduces the oversize of the product after previous blending. Applications: |
