The magnetic drum separator had a rotating drum (external diameter=20 cm, depth=12.5 cm, and with an arrangement of fifty neodymium magnets of 5 × 2 × 0.5 cm on its inner side) mounted on a cylindrical plastic container by a metal shaft (Salinas et al. 2018).The magnetic particles drop off at the bottom position of the drum as it passes out of the magnetic field, while the nonmagnetics are not attracted or held and slide off the top of the rotating drum with a normal trajectory. The separator has been used for sizes ranging from 3.8 cm to 0.150 mm (1.5 in. to 100 mesh) with capacities6 Magnetic Separation Springer

Assessing the performance of a novel pneumatic magnetic separator for
For instance, a dry magnetic separator with magnetic field alternating in the axial direction of drum was reported effective to separate iron ores at particle size from dozens to hundreds of millimeters, while another one with magnetic field alternating in the circular direction of drum was found suitable for much finer particles (Svoboda, 2004).They are mainly composed of the magnetic assembly, the rotating drum, the separation chamber, etc. The magnetic assembly includes 7 rectangular permanent magnets and a magnetic yoke with fixed functions. The magnet size, material properties, arrangement, and drum diameter of the four modes are identical, respectively.Separating efficiency of ferromagnetic particles and principle of

The ‘Air Gap’ plays a key role in the performance of a Magnetic Separator. In all magnetic separators, there is a gap between the magnet material or electromagnetic coil and the targeted particle. This ‘air-gap’ could be actual air or a non-metallic material such as stainless-steel or a rubber belt.Magnetic Separator Air-Gap Explained Bunting Redditch

The performance of the separator depends on both the size and the size distribution of the feed. The correlation between the different size fractions of the feed, e.g., − 0.6 +0.106, −0.6 + 0.A magnetic separator is provided in which a conveyor belt is conducted over a belt drum to transport relatively electrically conductive particles. A magnetic system consisting of permanent magnets or electromagnets is rotated at a high speed at an eccentric location within the belt drum so that an air gap between the outer surface of the magnet system US5092986A Magnetic separator Google Patents
