Magnetic Separator Innovation Contribute to Mineral Processing Industry

Author : Fote Last Updated : Sep 27, 2019

The magnetic separator market has broad prospects, and the competition is fierce and rapid. From 2018 to 2025, the annual compound growth rate of the global magnetic separator market value will continue to grow.

The magnetic separator is a screening device for removing iron powder in the reuse of powder granules. It is widely used in resource recovery, wood, mining, kiln, chemical, food and other workshops, suitable for wet magnetics of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size below 3 mm.

It is also used in the iron removal operation of coal, non-metallic minerals, building materials and other materials, which is one of the most widely used and highly versatile machines in the industry.

The rapid development of the mining industry in the past few years has stimulated the progress of the magnetic separator industry. The development of the mineral processing industry is inseparable from the advancement of magnetic separator equipment, and the innovation of magnetic separators can also promote the mineral processing industry. The development of the two is complimentary.

The magnetic separator is divided into two types. The permanent magnetic separator is mostly 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- 400 mT. 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.

According to the strength of the magnetic field, the magnetic separator is divided into three types: weak, neutral and strong. Weak magnetic separators are mainly used to treat ferromagnetic minerals such as titanomagnetite, ferrosilicon, and magnetite.

Strong magnetic separator is also called high-strength magnetic separator or super magnetic separator. It is a general term for magnetic separators with magnetic fields above 10,000-16000 GS. It is mainly used for magnetic separation of hematite, limonite, manganese ore, red mud and other weak magnetic ores.

The medium magnetic separator separates the partially oxidized and ferromagnetic minerals. Among these three parts, the medium magnetic separator is expected to grow at a high rate due to the growth of the beneficiation equipment market.

The segmentation of the magnetic separator market is also based on materials, namely wet magnetic separators and dry magnetic separators. The market share of wet magnetic separators has gradually narrowed, and the market for dry magnetic separators has been further strengthened due to limited water resources and demand for process efficiency.

The continuous innovation of magnetic separator is inseparable from the reform and efforts of magnetic separator manufacturers, and the stimulating factor is the ever-changing demand of customers for magnetic separator equipment. Efficient and energy-saving is the common goal of every magnetic separator manufacturer, but it is also a difficult goal to achieve perfection.

However, leading magnetic separator manufacturers are focusing more on technology development and product design, as magnetic separators are in short supply on the market and it is one of the main inputs for manufacturing magnetic separators.

In terms of the number of producers, the global magnetic separator market is highly fragmented and competition is largely dependent on performance and technology updates. The main players in the magnetic separator market focus on R&D activities to introduce advanced and cost-effective products to end-users.

The development of magnetic separator equipment depends on the joint efforts of users and merchants. Every advancement of magnetic separator equipment will have an inestimable effect on the mineral processing industry. The magnetic separator equipment has become more intelligent and automated, and the mineral processing industry will also take a new step.
