Vertical ring magnetic field magnetic separators are single-ring and double-ring, electromagnetic, and permanent magnet. Wherein, p1500mm double vertical ring strong magnetic separator electromagnetic better performance, the dividend is selected from iron ore for obtaining a good indicator. The φ1500mm double vertical ring magnetic separator consists of the ore feeder, magnetic system, sorting ring, ore collecting tank, flushing water pipe and transmission mechanism, as shown in Figure 1. The magnetic system consists of a yoke (the base l, the support plate 2 and the main shaft 5 together form a yoke), an iron core (reference numeral 3 is an iron core, one on each side, one in the middle) and an excitation coil 4, forming a "day" word. Type closed magnetic circuit. The two air gaps between the three cores are the magnetic field regions from which the sorting chamber of the sorting ring passes. There are two sorting rings, which are installed vertically on the horizontal main shaft. The whole sorting ring is divided into 40 sorting chambers by non-magnetic materials. The indoor φ6mm～φ20mm iron balls are used as the sorting medium, and the loading rate is 85%~ 90%. The inner and outer periphery of the ring, that is, the upper and lower bottoms of the sorting chamber are stainless steel sieves. When entering the magnetic field, the upper bottom enters the mine and prevents coarse particles and debris from entering the sorting chamber, and the bottom bottom discharges the tailings. During operation, the slurry is fed into the sorting chamber of the sorting ring located in the magnetic field of the core gap, where the iron ball is magnetized, and a non-uniform strong magnetic field is generated near the contact point between the ball and the ball, which can attract magnetic ore particles; non-magnetic The ore particles are not affected by the magnetic force and flow out into the tailings trough with the slurry flowing from the gap between the balls. The magnetic mineral particles that are sucked rotate with the ring and rise to the top without magnetic field. At this time, the sorting chamber is inverted, and the high-pressure flushing water at the top flushes the magnetic ore particles into the concentrate tank, and the selection is continued. The biggest advantage of this machine is that the sorting room is not easy to block. Because the sorting room is equipped with a loose ball medium, each sorting room is moved from the bottom to the top of the ring. The chamber rotated 180° and the ball was loosened in the sorting chamber, and the magnetic ore particles were easily washed down by water. The main point of operation of the machine is to select the diameter of the ball medium, because the ore particles pass through the gap between the balls, the coarser the grain size of the ore, the larger the gap between the balls, otherwise the ore particles will not pass. If the gap is large, the diameter of the ball will be large; but the larger the ball diameter, the fewer the number of balls added, and the fewer the ball contact points, the less the collection point for the magnetic ore particles, which is unfavorable for the selection. Generally, the diameter of the ball is 7 times the maximum particle size of the ore.
