Abstract
- This paper demonstrates the feasibility of using a ceramic medium stirring mill to reduce the energy consumption of grinding operations through an industrial verification experiment. Compared with the original two-stage ball milling process, the cost of grinding power consumption is significantly reduced by about 50.16%, which provides a reference for the subsequent research on energy saving and consumption reduction in ball milling operations. The optimal grinding parameters were determined to be grinding concentration of 50%, material ball ratio of 0.6, 3:2:5 media ratio (10:15:20 mm) of 3:2:5, medium filling rate of 90%, as well as stirring speed of 110 rpm. Under the optimum grinding parameters, an iron concentrate with an iron grade of 68.18% and an iron recovery rate of 94.17% were obtained by two-stage magnetic separation. The successful case of ceramic medium stirring mill replacing two-stage ball grinding provides a feasible solution for energy conservation and consumption reduction in mines in China. [Display omitted] • An industrial validation test of reducing energy consumption in grinding operations. • The applicable grinding parameters were determined by experiment. • A 36-h stable operation experiment was carried out. • The ceramic media stirring mill were studied.
