Vanadium titanium magnetite beneficiation equipment can be made of stainless steel or other wear-resistant plastic materials. The sorting barrel can also be made of other wear-resistant materials that do not block magnetic lines of force.
Depending on the throughput, the sorting drums can be manufactured in different sizes. For example, the diameter of the sorting cylinder can range from 0.5 meters to 10 meters. The length of the sorting cylinder can range from 3 to 15 meters. It can be understood that according to the type of material to be separated and the rotation speed, the size of the sorting barrel can be determined according to the specific situation. As long as the mineral materials in the sorting chamber of the sorting barrel are affected by a large enough magnetic field, Can be adsorbed to the inner wall of the sorting cylinder.
The feeding mechanism 250 is arranged at the left end of the sorting tube 210 , and the discharging mechanism 260 is arranged at the other end of the sorting tube 210 . In the embodiment shown in the figure, the sorting tube is open at both ends, and the opening of the sorting tube at the feed end is smaller than the opening at the discharge end. For example, the sorting cylinder can be provided with a reduction portion on one side of the feeding mechanism to prevent the mineral material from flowing out.
It can be understood that the sorting cylinder can also be a cylinder with one end open and the other end closed. Correspondingly, the feeding mechanism and the discharging mechanism are arranged on the same side, that is, they are arranged on the open side of the sorting barrel. In this case, the feeding mechanism includes a device that transports the mineral materials to the other side of the sorting barrel. (feed end) pipe.
In other embodiments, the sorting cylinder can also be arranged to slope downward from the inlet end toward the outlet end. That is, the central axis of the sorting cylinder at the outlet end is lower than the end at the inlet.
In the formula of vanadium-titanium magnetite mineral processing equipment, the sorting cylinder can be a frusto-conical cylindrical structure. The sorting cylinder gradually expands from the inlet end to the outlet end, so that the material can move from the inlet to the outlet under the action of gravity. Move slowly. The taper of the sorting cylinder ranges from 2 to 15 degrees.
During the beneficiation process, the rotation speed of the sorting cylinder can be between 5-20 rpm, preferably between 8 and 15 rpm. It can be understood that the rotating speed of the sorting cylinder can also be other suitable rotating speeds.
In addition, the appropriate feeding speed needs to be selected according to the actual situation. In the mineral processing equipment according to the present invention, the feeding speed of the mineral materials entering the classification cylinder can be, for example, 20 tons (T) per hour. The maximum can be as high as 100-200T per hour.
The magnetic field generating device 220 is arranged around the sorting chamber 215 . The magnetic field generating device may be two sets of magnetic plates arranged in the circumferential direction of the cylinder, thereby generating a magnetic field in the circumferential direction of the sorting cylinder. Each set of magnetic plates includes two magnetic plates with corresponding magnetic poles, and N poles and S poles are arranged at intervals. The magnetic plates may be made of permanent magnets. In other embodiments, more sets of magnetic plates can be arranged on the barrel, such as 3 to 10 sets of magnetic plates (4 sets are shown in Figure 1B). It can be understood that, according to the size of the barrel, an appropriate number of magnetic plates can be arranged on the primary selection machine or the concentrator to generate a magnetic field on the circumference of the barrel of the concentrator.
The magnetic plate in the magnetic field generating device may also be an electromagnetic device.
A blocking magnetic ring (not shown) is provided at the discharge end of the sorting cylinder. Specifically, a strong annular magnetic field is set at one end of the sorting cylinder near the outlet to prevent magnetic substances, substances that can induce magnetism, or other substances that can be affected by the magnetic field from flowing out of the sorting tube. The magnetic field intensity of the toroidal strong magnetic field is preferably greater than 4000gs (Gauss), and further the magnetic field intensity of the magnetic field is greater than 5000gs.
In the magnetic field generating device based on the vanadium-titanium magnetite mineral processing equipment, the magnetic field strengths of different magnetic plate groups can be different, and a changing magnetic field for selected minerals is generated in the classification chamber. The magnetic field intensity of the magnetic plates constituting the magnetic field generating device may be between approximately 3000gs (Gauss) and 6000gs. When used for fine separation of mineral powder, the magnetic field strength of the magnetic plate can be in the range of 0 to 2000gs. Magnetic plates of different strengths can be distributed alternately or continuously.
