For the normal operation of some equipment, we sometimes need to remove iron from them, which requires permanent magnet iron remover. Do you know the selection method of permanent magnet iron remover? Let's follow the manufacturer of permanent magnet iron remover to understand. Compared with electromagnetism, permanent magnet has the advantages of low energy consumption and low operation cost. According to the iron content of different ores, different combinations of different types of permanent magnet iron removers are used. Normally, the higher the background magnetic field strength is, the better the requirement is. The high gradient iron remover does not rely on the surface of background magnetic field to absorb iron, but through different magnetic gathering media, to achieve iron removal scheme and form a differentiated mining and beneficiation process 。 Iron removal is a very important process in non-metallic mining and beneficiation. Due to the improper selection of permanent magnet iron remover, the equipment selection is different. First, the selection of dry and wet iron removal methods. According to the different iron content in the ore, different types of (electromagnetic, permanent magnetic) permanent magnet iron removers are equipped to form different mining and beneficiation processes. The work area with high field strength and high gradient can absorb the iron impurity to the medium surface. This background field strength can be measured by Gauss meter or calculated to get the theoretical value. Magnetic force is mainly related to the following factors: the magnetism of particles, the size of particles. The fundamental principle of separation is the competition between magnetic force and other forces. Any permanent magnet iron remover is based on the principle of the magnetic difference of different materials in the processed materials. The stable operation of the equipment directly affects the quality consistency of the products, and also directly affects the output per unit time. The magnetic force is the root to solve the problem, which directly leads to the waste of equipment capacity and equipment investment, low labor cost, direct impact on business efficiency, simple operation and maintenance It is convenient to repair, and the requirements for workers' skills are not high. Production demand is the basis of equipment capacity allocation. Different beneficiation processes are the reasonable matching of production capacity. However, at present, the capacity of dry-type iron removal equipment can not meet the needs of users. At present, wet iron removal process is stable and widely used in the industry, which is an ideal way of iron removal. Dry iron removal has become the development trend of iron removal in the industry. The above is the selection method of permanent magnet iron remover. I hope the above information can help you. If in doubt, please consult the manufacturer of permanent magnet iron removal equipment.
