Technical Field
The invention relates to a dynamic magnetic force capturing device for a rotary magnetic medium, and belongs to the technical field of mineral separation.
Background
To date, almost all magnetic media used in high gradient magnetic separation processes have been subjected to magnetic force capture processes in a stationary or quasi-stationary (e.g., low velocity motion) state. Because the magnetic medium is kept in a (quasi) static state, the magnetic force capturing process and the qualitative observation and quantitative measurement of the behavior of the magnetic medium are reported in related methods, such as a Chen Luzheng unit medium analysis method and a magnetic medium monofilament capturing analysis method, which are respectively used for solving the technical problems of magnetic medium filament arrangement and combination optimization and magnetic medium monofilament capturing. The magnetic medium rotation capturing is an important form for realizing the high-gradient magnetic separation process, such as a centrifugal high-gradient magnetic separation method, namely, the magnetic capturing mode is adopted, and the magnetic medium rotation capturing method has the unique new separation characteristic. Unlike (quasi) stationary magnetic media, in the process of capturing rotating magnetic media, the magnetic force capturing process cannot be clearly observed and accurately measured due to the rapid movement of the magnetic media, which restricts the research and development of related high-gradient magnetic separation technologies to a great extent.
