Title:
LOW-FREQUENCY ALTERNATING-CURRENT ELECTROMAGNETIC ELUTRIATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/186596
Kind Code:
A1
Abstract:
A low-frequency alternating-current electromagnetic elutriating machine, comprising: a washing separator (1), a concentrate cone (5), an overflow device (2), an ore feeding device (3), a water supply device, and a magnetic separation device. The magnetic separation device comprises ore gathering magnetic field coils (11) sleeved on the top of the outer periphery of the washing separator (1) and a plurality of traveling-wave magnetic field coils (9) located below the ore gathering magnetic field coils (11). Single-phase low-frequency alternating-current is fed into the ore gathering magnetic field coils (11), and three-phase low-frequency alternating-current is fed into the traveling-wave magnetic field coils (9). The traveling-wave magnetic field coils (9) are connected in "Y" or "△" shape. The frequency of the low-frequency alternating-current is lower than 50 Hz. Inductive magnetic rings (4) are provided at the positions corresponding to the ore gathering magnetic field coils (11) inside the washing separator (1). An inner overflow cylinder (21) has the same diameter as the washing separator (1). The ore outlet of the ore feeding device (3) is located at the middle between first and second traveling-wave magnetic field coils (9a, 9b) and the middle of between the inner wall of the washing separator (1) and the outer wall of an ore feeding pipe (31). A water supply device is provided in the concentrate cone (5) below the washing separator (1). The low-frequency alternating-current electromagnetic elutriating machine can achieve a high concentrate grade and good sorting effect, and has a wide range of application.
