Category: Magnetic Separation Equipment
Magnetic roller
- Product Introduction: A dry magnetic separation equipment for pre-selection of coarse-grained highly magnetic minerals.
- Capacity: 100t/h-350t/h
- Applications: It is used for dry pre-selection of magnetite before grinding, and the selected particle size is below 300mm. Usually, an appropriate amount of tailing can be thrown to improve the grinding grade to above the geological grade.
- Product Improvements: Large magnetic wrap angle design, magnetic wrap angle < 180°, increases the length of the sorting belt and the number of magnetic flips, achieving effective separation of magnetic minerals and non-(weak) magnetic minerals.
Advantages and Features
- The magnetic system of Huston strong magnetic rollers all uses neodymium iron boron magnets with high magnetic energy product and high coercivity, which have high magnetic field intensity and large depth of action
- the demagnetization rate of magnetic field strength does not exceed 5% in 8 years
- the magnetic system is coated with non-magnetic stainless steel to ensure that the magnets will not fall off
- the cylinder body of this strong magnetic roller is made of non-magnetic stainless steel and coated with wear-resistant rubber, which significantly improves the service life of the cylinder
- the permanent magnet roller can be used as either a driving roller or a driven roller.
Working Principle
Magnetic drums are usually used as transmission drums for conveyor belts. When materials pass through the magnetic drum on the conveyor belt, they are sorted. Magnetic materials are attracted when they move to the top of the drum and fall off automatically when they move to the bottom. Non-magnetic materials fall directly along a horizontal parabolic trajectory. Magnetic materials and non-magnetic materials will enter different receiving hoppers respectively.

Case Study
In an iron concentrate concentrator, the lean iron ore is subjected to magnetic separation after coarse and medium crushing. In order to restore the grade, save energy and increase production, a permanent magnet drum magnetic separator is selected to reduce the load of the next process. Arranged with two sections of magnetic separation, the magnetic field intensity is large, the magnetic separation effect is very obvious, and the production efficiency is improved; it can also be used to process tailings, which facilitates the reuse of equipment, saves costs, and improves grade.
