Abstract.

The paper determines main operational characteristics of magnetic spiral classifier in terms of hydroclassification processes, design parameters and mode indications. A magnetic spiral classifier with constant magnetic field was designed for improving selectivity of the pulp separation by material composition and using basalt raw materials (tuff, basalt, lavabreccia) in technology of the ore pretreatment. Findings of this study make possible to specify limits for the classification process and calculate basic characteristics of the magnetic spiral classifier, floccules density and rate of their deposition depending on magnetic field strength.

Keywords:

hydraulic classification, magnetic field, floccules, deposition rate.
