The purpose and principle of magnetic separation
发布时间：2020-07-05 点击次数：
The main purpose of magnetic separation during the cleaning process is to protect various types of process equipment, especially equipment that has a strong effect on raw materials such as wheat mills and mills, so before the raw materials enter the cleaning process or enter the equipment to be protected , Should be magnetic separation. In order to remove the metal powder mixed with flour in the grinding process and ensure the purity of the product, magnetic separation should also be performed before the finished product is packaged.
The iron impurity in the raw material is completely different from wheat in magnetic permeability characteristics. A permanent magnet with a certain magnetic induction strength is used as the main working structure. Within its effective magnetic field range, the iron impurity in the raw material can be absorbed to achieve the iron impurity Separation with corn. Magnetic separation cannot remove non-ferrous metal impurities.
The magnetic separation equipment is generally simple, most of them do not require power, and the volume is small, and the efficiency of removing iron and impurities can reach more than 95%.
