THE RESEARCH AND MANUFACTURE OF VERTICAL SPIRAL AGITATING MILL AND LTS APPLICATION IN REGRINDING AND SCRUBBING MOLYBDENUM ORE

This paper presents the basic structure and work principle of the vertical spiral agitating mill,whose design and manufacture are based on the engineering enlargement principle that combines the method of computational flow field numerical simulation with the conventional mechanics analysis together.The paper pays much attention to the application of vertical spiral agitating mill in regrinding and scrubbing molybdenum ore.During its processing,the mill greatly improves the grade of monomial dissociation by particle size reduction and surface cleaning of molybdenum ore,creating good flotation environment and thus apparently raises the grade and recovery rate of its concentrates.Vertical spiral agitating mill's put into industrial production shows and proves its excellent performance in regrinding,fine grinding and scrubbing.
