PTMS MAGNETIC SEPARATOR

what is magnetic separation method？

The magnetic system is the main component of the magnetic separator. The performance of the magnetic separator is not only related to the magnetic material and magnetic field characteristics, but also has a great relationship with the magnetic structure. The weak magnetic field magnetic separator is generally designed as an open magnetic system, which is composed of a magnetic pole and a bottom plate and a yoke which are bonded and laminated by a permanent magnet magnetic block. This is a three-stage magnetic system, the magnetic system wrap angle a, the distance between adjacent magnetic poles is L, and the magnetic force line starts from the N pole to reach the S pole through a large air gap. The magnetic field formed due to the large magnetic resistance of the air It is a weak magnetic field, so it is suitable for selecting ferromagnetic minerals. The strong magnetic system is a closed magnetic system composed of a magnetic pole, a core, a coil, a yoke, and a working disk. Due to the small air gap between the magnetic poles, a strong magnetic field is easily generated. Therefore, the strong magnetic field magnetic separator of the weak magnetic mineral is designed to close the magnetic system. In order to further increase the magnetic field force of the closed magnetic system, the air gap can be reduced to reduce the magnetic resistance. However, this will reduce the selection space and reduce the processing capacity of the device. Therefore, the magnetic field is improved from the form of the magnetic pole pair and its geometric size, and a magnetic magnetic medium with a high magnetic permeability between the two magnetic poles is used to increase the magnetic field. force. For example, if an integral sensing medium (rotary roller, rotating cone or turntable) is placed between the two original magnetic poles to form a magnetic circuit, a plurality of sensing media (shaped plates, balls, etc.) having a certain shape may be placed between the original magnetic poles. A column or a net, etc.) constitutes a magnetic circuit. The magnetic separator generally has two major functions: iron selection and iron removal, iron selection such as: hematite, limonite, magnetite, manganese ore, ilmenite, siderite and other magnetic metal mines, iron removal Such as: lime removal of iron, cement and iron removal.
