Guangzhou colored homes development, production SSS series dual-band dual wet vertical ring high gradient magnetic separator (FIG. 1) is a new and efficient magnetic separation apparatus, since the unique dual pulsers, able to combine the concentrate mass and the metal recovered The rate can not only obtain high-grade concentrate, but also reduce the grade of tailings to a certain extent. The selection index can be flexibly adjusted according to the needs of the process. There are two types of equipment in this series, namely SSS-I type (invention patent ZL02114994.1) and SSS-II type (invention patent ZL02134298.9).
Due to the high background magnetic field strength and high magnetic field gradient, SSS-I is suitable for metal ore rough selection, sweeping and non-metallic mineral purification. The technical parameters are shown in Table 1.
Sorting principle and sorting process: The structure of the SSS-I type high gradient magnetic separator is shown in Fig. 2. When the exciting coil 1 is supplied with a large current of direct current, a magnetic field having a high intensity is formed in the sorting space, and the surface of the collecting magnetic medium 2 forms a high magnetic field force in the magnetic field. The sorting ring 3 is rotated clockwise by the cycloidal pin motor 4 (or the transmission motor and the speed reducer) and the pair of gears 5, and the lower portion is formed by the upper magnetic pole 12 and the lower magnetic pole 13 to form an arc sorting space, sorting Each of the sorting chambers on the ring 3 is filled with a magnetically permeable medium.
Due to the high background field strength and high magnetic field gradient, this model is suitable for metal ore rough selection, sweeping and non-metallic ore purification.
The slurry is uniformly entered into the sorting space by the feed hopper 6. Due to the magnetic field force, the magnetic mineral particles are adsorbed on the surface of the concentrating medium 2, and the tailing pulse mechanism 9 is adjusted so that the pulse frequency and the peak value are small, and the fluid power generated is thus generated. Very small, extremely weak magnetic and non-magnetic particles are subjected to a very small magnetic field force. They are subjected to fluid dynamics of the slurry greater than the magnetic field force, cannot be attracted by the magnetic medium 2 and enter the tailing hopper 10 through their gaps; The particle group on the surface of the magnetic medium 2 rotates with the sorting ring 3, and the tailings pulse mechanism 7 is adjusted to increase the pulse frequency and the peak value, so that the hydrodynamic force generated is enhanced, and other weak magnetic particles and continuum are received. When the magnetic force is less than the hydrodynamic force, they will leave the surface of the magnetically permeable medium 2 and enter the middle hopper 8 through the gap; the magnetically strong particles that are not detached are subjected to a magnetic force greater than the hydrodynamic force and are firmly absorbed in the magnetic concentrating medium. 2 The surface continues to rotate along with the sorting ring 3, gradually deviating from the magnetic field and entering the magnetic product unloading area. Since the magnetic field is weak in this area, the magnetic material is collected from the collecting magnetic material by the concentrate washing water. The surface of the mass 2 is washed down and enters the concentrate bucket 11, which is a magnetic product. Thereby, the particle groups having different magnetic properties are effectively separated.
Scope of application: This machine can choose the impurity removal and purification of weak magnetic minerals, medium magnetic minerals, ferromagnetic minerals and non-metallic minerals, for example:
Ferrous Metals: the illusion of hematite, hematite, limonite, siderite, manganese chromite ore and recycling.
Non-ferrous ore: the tungsten-containing quartz veins recovered fine disseminated wolframite, cassiterite isolated SULPHIDE DEPOSITS pyrrhotite. Separation of cassiterite with minerals such as wolframite and limonite, separation of scheelite from minerals such as wolframite and garnet.

Non-metallic minerals: purification of quartz, feldspar and kaolin in glass ceramics industry, de- ironing of high-temperature refractory sillimanite , andalusite , kyanite and removal of hornblende, mica, tourmaline , garnet, etc. Impurities, etc.
Other aspects: wastewater treatment in steel plants and power plants, cleaning of chemical raw materials contaminated by catalysts.
The main technical specifications and performance of the high gradient magnetic separator are shown in Table 2, and the components used are shown in Table 3.
SSS-II wet double frequency double vertical ring high gradient magnetic separator. The II type wet double-frequency double vertical ring high gradient magnetic separator developed and produced by Guangzhou Nonferrous Institute has a combination of horizontal left and right magnetic poles and vertical rings, which enhances the selectivity of magnetic products and can obtain high grade precision. mine. Its technical characteristics are shown in Table 4.
Sorting principle and sorting process: The structure of the SSS-II type high gradient magnetic separator is shown in Fig. 3. When the exciting coil 1 is supplied with a large current of direct current, a magnetic field having a high intensity is formed in the sorting space, and the surface of the collecting medium 2 can form a high magnetic field force in the magnetic field. The sorting ring 3 is driven by the motor and the reduction unit 4 and a pair of gears 5, and rotates clockwise, and the lower portion forms an arc-shaped sorting space through the left magnetic pole 12 and the right magnetic pole 13, and each of the sorting rings 3 is divided. The selected chamber is filled with a magnetically permeable medium.
This model combines the left and right magnetic poles with the magnetically permeable portion of the outer edge of the turntable to form a horizontal magnetic line of separation space and is combined with a unique dual-frequency pulse device. Therefore, the quality of the concentrate and the metal recovery rate can be achieved, and high grade can be obtained. The concentrate can also reduce the grade of tailings to a certain extent and adjust it with medium ore according to the needs of the process. This model is especially suitable for improving the concentrate grade and metal recovery rate.
The slurry is uniformly entered into the sorting space by the feed hopper 6. Due to the magnetic field force, the magnetic mineral particles are adsorbed on the surface of the concentrating medium 2, and the tailing pulse mechanism 9 is adjusted so that the pulse frequency and the peak value are small, and the fluid power generated is thus generated. Very small, extremely weak magnetic and non-magnetic particles are subjected to very small magnetic forces. They are subject to the fluid dynamics of the slurry greater than the magnetic field force and cannot be absorbed by the magnetically permeable medium 2 and enter the tailings bucket 10 through their gaps; The particle group on the surface of the magnetically permeable medium 2 rotates with the sorting ring 3, and the tailings pulse mechanism 7 is adjusted so that the pulse frequency and the peak value are increased, so that the hydrodynamic force generated is enhanced, and other magnetic weak particles and the joint are obtained. The magnetic force of the living body is less than the hydrodynamic force, and they will leave the surface of the magnetic magnetic medium 2 and enter the middle mining bucket 8 through the gap; the magnetically strong particle group that does not fall off is subjected to the magnetic force greater than the hydrodynamic force, and is sucked firmly. On the surface of the magnetically permeable medium 2 and continue to rotate along with the sorting ring 3, gradually detached from the magnetic field, and entered the magnetic product unloading area. Since the magnetic field is weak in this area, the magnetic material is washed with concentrate water. It is washed out from the surface of the magnetic magnetic medium 2 and enters the concentrate bucket 11, which is a magnetic product. Thus, a group of particles having different magnetic properties is effectively separated.
Scope of application: The high gradient magnetic separator can be used for impurity removal and purification of weak magnetic minerals, medium magnetic minerals, ferromagnetic minerals and non-metallic minerals, for example:
The ferrous metal mine: imaginary recovery of hematite, hematite, limonite, siderite, chromite and manganese ore.
Non-ferrous metal ore: recovery of fine-grained inlaid wolframite in tungsten-containing quartz veins, separation of pyrrhotite in cassiterite polymetallic sulfide ore.
