A Way of Boosting Up the Efficiency of Hydraulic Classification in the Spiral Classifier of Grinding & Processing Plant No. 5 of the ROF of the OJSC "Magnitogorsky Iron & Steel Works"
In order to improve efficiency of hydraulic classification in industrial environment of Grinding & Processing Plant No. 5 (DOF-5) within Ore Beneficiation Plant (ROF), the operation of «mill - classifier» assembly with the overflow elevation increasing in areas of higher velocity to prevent the ingress of off-grade coarse particles into the overflow was investigated. This feature allows for a higher volume of classification zone and, consequently, results in lower density of separated pulp and enhanced process efficiency, as coarse classes deposit faster and finer classes are densely carried away into the overflow.
