Faris S. Automatic control method of drum mills loading degree with ore on magnetic concentration plants

The thesis deals with the actual scientific problem to establish new regularities in forming compatible active power signals of mill electromotor and magnetic separator in technological complexes for iron ore magnetic separation. The relation between the signals and drum mills loading degree is studied with variable physical and mechanical properties of ore taking into account. Method and system for automatic control of drum mills optimal loading degree are developed. The method and the system allow increasing technological complexes productivity and iron ore concentrate quality. Scientific basis is given to functional and algorithmic structures and specifications for the automatic control system by the active power signals of mill and separator motor drives. Results of the study are implemented at JSC "Centralniy GOK", Krivoy Rog and can be used for iron ore magnetic enrichment factories in Ukraine and abroad.
