high gradient magnetic separation

PTMS MAGNETIC SEPARATOR

what is magnetic separation？

According to the distribution of the magnetic field strength, there is a distinction between a uniform magnetic field and a non-uniform magnetic field. The so-called uniform magnetic field means that the magnitude and direction of the magnetic field strength at each point in the magnetic field are the same. A non-uniform magnetic field is the magnitude and direction of the magnetic field strength at each point in the magnetic field. As shown, the distribution of magnetic lines of force is uniform in a uniform magnetic field, and the distribution of magnetic lines of force is not uniform in an inhomogeneous magnetic field. The degree of non-uniformity of the magnetic field can be measured by a magnetic field gradient, which is the value of the change in magnetic field strength per unit distance (for example, 1 cm), as shown. Let the magnetic field strength at the N pole x1 be H1 and the magnetic field strength at the distance x2 be H2. The magnetic field gradient gradH should be: where the meaning is the amount of change in the magnetic field strength at a small distance between two points in the magnetic field. In a uniform magnetic field, =0, so the specific magnetic field of the ore particles in the uniform magnetic field F magnetic = xHgradH = 0, that is, no magnetic force. It can be seen from the above figure. The ore particles are magnetized in a uniform magnetic field. Because the magnetic fields at both ends are the same, the magnitude of the magnetic force is the same, but the direction is opposite. Therefore, the ore particles are only subjected to the torque, and when they are transferred to the long axis direction and the magnetic field direction of the ore particles. When they are consistent, they stop moving. In the uneven magnetic field, in addition to the torque effect, the ore particles are simultaneously subjected to different magnetic forces due to the different magnetic field strengths, that is, magnetic differences are generated at both ends of the ore particles, thereby showing that the entire ore particles are subjected to magnetic force. The action F magnetic = xHgradH ≠ O, and moves in the direction of high magnetic field strength. The above description: The magnetic field of the magnetic separator must be an inhomogeneous magnetic field, otherwise the magnetic ore particles cannot be attracted to the magnetic pole, and thus magnetic separation cannot be performed.
