Stainless Steel Rotary Iron Remover | High Intensity Magnetic Separator | Wear-Resistant Design for Dry/Wet Materials.
A rotary iron remover/magnetic separator is a device used to separate magnetic and non-magnetic substances. The following is an introduction to it:
The rotary iron remover/magnetic separator mainly utilizes the strong magnetic field generated by permanent magnets or electromagnets to adsorb magnetic particles in the materials onto the surface of the rotating drum. As the drum rotates, the magnetic particles are carried to a designated position, and then they are separated from the drum through a scraper or other means, thus achieving the separation of magnetic substances from non-magnetic substances.
- Drum: Usually made of stainless steel or wear-resistant materials, with a smooth surface to ensure that magnetic particles can be adsorbed and separated smoothly. Permanent magnets or electromagnetic coils are installed inside the drum to generate a magnetic field.
- Drive Device: It provides power to make the drum rotate, generally composed of a motor, a speed reducer, and a coupling, etc. The drive device can precisely control the rotation speed of the drum to meet the separation requirements of different materials.
- Frame: It supports the entire equipment. Usually, it is made of a steel structure and has sufficient strength and stability to ensure that the equipment will not shake or deform during operation.
- Feeding Device: It uniformly conveys the materials to be separated onto the surface of the drum, ensuring that the materials can fully contact the drum under the action of the magnetic field and improving the separation effect.
- Discharging Device: It includes components such as a scraper and a belt, which are used to scrape off the magnetic particles adsorbed on the surface of the drum or convey them to a designated collection container.
- In the Mining Field
- Ore Pre-selection: In the initial stage of mining, the rotary magnetic separator can quickly separate magnetic ores from a large amount of gangue, improving the grade of the ores to be selected later, and reducing the transportation and ore grinding costs. For example, in magnetite mining, it can pre-concentrate magnetic iron minerals and reduce the processing amount of ineffective minerals.
- Tailings Recycling: Conduct a secondary screening of the tailings to recover the residual magnetic minerals in them, improve the utilization rate of resources, and reduce the environmental pressure caused by tailings discharge. Some magnetic minerals such as a small amount of iron and manganese in the tailings can create additional economic value after being recovered by the rotary magnetic separator.
