Principle of operation of rare earth roll How do rare earth magnets work? There are two main types of rare earth magnets rare earth rolls and rare earth drums. Process widths are usually 1m to 1.5 m, with 2 4 magnetic stages. In a rare earth roll, material is fed evenly on its separator belt and is transported over a uniquely designed
The Rare Earth Roll separator was designed to provide peak separation efficiency and is typically used when a high level of product purity is required. The roll is constructed with permanent magnetic discs alternating with thin steel pole pieces along a shaft. The steel poles are saturated with magnetic fluxRead More..
In the simplest approach, a small permanent magnet can be used, but various magnetic separators employing strong rare earth magnets can be obtained at reasonable prices. Commercial laboratory scale batch magnetic separators are usually made from magnets embedded in disinfectant proof material. The racks are constructed for separations in
20/02/2017· In these cases, the highly specialized nature of magnetic separators quickly comes to the forefront. Rare Earth Magnetic Separators. Rare earth magnets are specially employed in times when its necessary to seek out fine metal particles and magnetically active debris from materials that are moist or powdery. They are available as standard plate magnets, plate
Rare Earth Roll Magnetic Separator Overview The Reading Rare Earth Magnetic Roll Separator provides a unique inclined belt feeding system to maximise overall performance and efficiency. The design of the magnetic rolls ensures the optimum combination of magnetic field strength and magnetic gradient to give the most effective separation. Features
11/09/2017· This curve illustrates that the salient pole rare earth drum is more selective than the roll type separator. It should be noted, however, that at lower recovery values, the curves converge. In this situation, either separator can be used to achieve the desired separation performance, although capacity clearly favors the drum type separator.
22/10/2018· The Rare Earth Roll Magnetic Separator can process a wide size range of material ranging from 75 microns up to 15mm. Although, as with all physical separation processes, a tight control of the particle size range improves separation efficiency. Industrial Scale Rare Earth Roll Magnetic Separator
29/04/2015· As a result, separators of different magnetic flux, or power, can be used. There are 2 types of magnetic separators; electromagnetic and permanent. Electromagnetic separators generate a magnetic field by switching power from alternating current to direct current. Electromagnetic separators are useful for removing large pieces of tramp ore from the bulk
