The magnetic separator is used to remove iron powder from powder granules. The magnetic separator is widely used for resource recovery, wood, mining, kiln, chemical, food and other workshops. It is suitable for magnetic materials with a particle size of 3mm or less. Wet magnetic separation of iron ore, pyrrhotite, roasting ore, ilmenite and other materials, also used in iron removal operations of coal, non-metallic minerals, building materials and other materials, is the most widely used and highly versatile in the industry. One of the models. The magnetic separator is one of the most widely used and highly versatile models in the industry and is suitable for separation of substances with magnetic differences. Magnetic separators are widely used in mining, timber, kiln, chemical, food and other industries. For the mining industry, the magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, pyrrhotite, roasting ore, ilmenite, and limonite ore with a particle size of 50 mm or less. Removal of iron from coal, non-metallic minerals, building materials and other materials. The magnetic separator is divided into two types. The magnetic system of the permanent magnet magnetic separator is made of high-quality ferrite material or composited with rare earth magnet. At an early stage, the average magnetic induction intensity of the magnetic cylinder of the magnetic separator is 80- 400mT. With the continuous development of technology, the magnetic separator can be made into a roll shape, and the magnetic field strength is also increased to 1650 mT, which is the highest measured magnetic field strength.
