What's the difference between a permanent magnet roller and a strong magnet roller?

The advantages of permanent magnet roller are:

★ The permanent magnet electric drum has two invention patents and three utility model patents, with less equipment configuration, small occupied space and full load start.

Good performance, wide speed range, low failure rate and basically maintenance-free.

★ It can be interchanged with the original drum with the same size, without replacing the magnetic head mounting frame, thus solving the problem of field transformation.

★ The drum has a non-return function (patented technology), which conforms to the provisions of Article 374 of the Coal Mine Regulation.

★ The drum has braking function (patented technology, optional), which conforms to the provisions of Article 374th (5) of the Coal Mine Regulation.

★ The drum has cooling function and adopts closed-loop cooling mode, so the cooling performance is more reliable.

★ The control system adopts explosion-proof frequency converter and PLC control, which has good starting performance, remote communication, temperature and flow monitoring and other functions.

★ High energy saving: the comprehensive efficiency of the drum is more than 93%, and the power factor is more than; 99%, the system energy saving can reach more than 30%.

Their main differences are:

Permanent magnetic drum and strong magnetic drum are mainly used for magnetic separators or iron separators. Suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with particle size less than 3mm, and also for iron removal of coal, non-metallic minerals, building materials and other materials. They are one of the drum types widely used in industry and have high versatility.

The permanent magnet drum is wrapped with double-layer barrel skin, which protects the internal structure well under the premise of magnetic force, saves maintenance cost and enables the machine to run all the year round. Even if it is replaced, the outer tube skin needs to be replaced. The magnetic system inside the drum is made of rubidium, boron and other materials, which is not easy to demagnetize, and it is still good after ten years of use, with stable magnetic system and good beneficiation.

The magnetic field on the surface of the strong magnetic roller has a large span and is easy to choose. It can be divided into ordinary magnetic field and strong magnetic field. The magnetic field is stable, the service life is more than ten years, the magnetic circuit provides eight-year quality, the machine body structure is simple, the operation is convenient, the magnetic field has high magnetic range, no energy consumption, continuous operation, large color angle and less ore leakage, and it can continuously and automatically separate ferromagnetic impurities in non-magnetic materials on the conveyor belt, and the processing capacity is dozens of times that of ordinary equipment. roll

Barreled iron has high recovery rate and large capacity, which can reach 300 cubic meters per hour. The recovery rate of iron can reach 90%, and the grade of iron is high. Usually, the grade of paste can be increased to about 70%.
