what is magnetic separation method？
Classification method of magnetic separation equipment: The structure of magnetic separation equipment is various, and there are many classification methods. It is usually classified according to some of the following characteristics.
1. According to the strength of magnetic field and the strength of magnetic field, it can be divided into weak magnetic field magnetic separator and strong magnetic field magnetic separator;
2, according to the selection of media can be divided into (1) dry magnetic separator selected in the air, mainly used to select large, coarse-grained strong magnetic ore and fine-grained weak magnetic ore. At present, it is also intended to be used to select fine-grained ferromagnetic ores; (2) Wet magnetic separators are selected in water or magnetic liquids. It is mainly used to select fine-grained ferromagnetic ore and fine-grained weak magnetic ore.
3. According to the method in which the magnetic ore particles are selected, it can be divided into: (1) the selected material of the suction magnetic separator is given a certain distance from the working magnetic pole or the transportation component, and the magnetic ore particles are sucked out from the material, after a certain period of time. Only on the working pole or on the surface of the transport component. This magnetic separator generally has a better concentrate quality. (2) The selected material of the suction magnetic separator is directly fed to the working magnetic pole or the surface of the transporting member, and the magnetic mineral particles are sucked on the working magnetic pole or the surface of the transporting member. The magnetic separator generally has a high recovery rate; (3) the selected magnetic separator is supplied to the surface of the working magnetic pole at a certain distance, and the magnetic ore particles are attracted to the surface of the working magnetic pole under the action of gravity. Discharged into a magnetic product. 4. According to the direction of movement of the incoming material and the method of discharging the selected product from the selected zone, it can be divided into (1) the moving direction of the selected material and the non-magnetic ore particle of the downstream magnetic separator is the same, and the magnetic ore is deviated from this. Direction of movement. Such a magnetic separator generally cannot obtain a high recovery rate; (2) the direction of movement of the selected material and the non-magnetic ore particles of the countercurrent type magnetic separator is the same, and the direction of movement of the magnetic product is opposite to this direction. The magnetic separator generally has a high recovery rate; (3) the selected material of the semi-reverse flow type magnetic separator is fed from below, and the magnetic or non-magnetic ore particles move in opposite directions. This magnetic separator generally has higher concentrate quality and recovery rate.
5. According to the behavioral characteristics of magnetic ore particles in a magnetic field, it can be divided into: (1) a magnetic separator with a magnetic flipping action. In this magnetic separator, a magnetic flux composed of magnetic ore particles is partially or during its movement. All destroyed. This is conducive to the improvement of the quality of the concentrate; (2) Magnetic separator without magnetic flipping action In this magnetic separator, the flux linkage is not damaged, which is beneficial to the improvement of the recovery rate.
6, according to the structural characteristics of the discharged magnetic products can be divided into: cylindrical, conical, belt, roller, disc and ring, and so on.
7. According to the type of magnetic field, it can be divided into: (1) Constant magnetic field magnetic separator The magnetic source of the magnetic separator is a permanent magnet, a DC electromagnet, and a solenoid coil. The magnitude and direction of the magnetic field strength do not change with time; (2) The magnetic source of the rotating magnetic field magnetic separator is a permanent magnet with alternating polarities, which rotates rapidly around the axis. The magnitude and direction of the magnetic field strength change with time; (3) The magnetic source of the magnetic field separator of the alternating magnetic field is an alternating current electromagnet. The magnitude and direction of the magnetic field strength change with time; (4) The magnetic source of the pulsating magnetic field magnetic separator magnetic separator is an electromagnet that simultaneously transmits direct current and alternating current. The magnitude of the magnetic field strength changes with time, and its direction does not change. The most basic classification of a magnetic separator is based on the strength of the magnetic or magnetic force and the structural characteristics of the discharged magnetic product. Magnetic separation equipment refers to the separation of magnetic materials from other materials by magnetic devices according to the magnetic characteristics of the materials. The equipment used for such operations is called magnetic separation equipment, and is generally used as magnetism and other magnetic materials. Production screening of minerals. Magnetic separation equipment is also commonly called magnetic separators, magnetic separation machines, and the like.
