Abstract

1,059,808. Magnetic separators. INDIANA GENERAL CORPORATION. Oct. 4, 1965 [Nov. 16, 1964], No. 41945/65. Heading B2J. Ceramic magnetic particles are obtained by supplying a slurry 32 of ferrite crystals and water to the underside of a nip region 30 between a pair of magnetic rollers 12, 13, conveying the magnetic particles through the nip region by means of conveyor belts 20, 21 while magnetically attracted by the rollers to squeeze water from the magnetic particles and to magnetically orientate the ferrite crystals while passing through the nip region to form ceramic magnetic particles, and applying heat as at 36, 41 to the particles for removing further water therefrom. Alternatively, one of the magnetic rollers may be replaced by a non-magnetic roller or by a demagnetized ferrous roller. The roller 13 is driven by the belt 21 which passes around a roller 17 which has an extended shaft portion on which is secured a pulley 25 driven via a belt 26 and pulley 24 from a motor 23. The roller 12 and belt 20 assembly is driven by frictional engagement with the roller 13 and belt 21 assembly, the belt 20 passing around an idler roller 16. The rollers 12, 16 and the rollers 13, 17 are mounted between supports 45, 46 and 47, 48 respectively, Fig. 2 (not shown). The end shaft portions of the rollers 16 and 17 are received in bearings, e.g. 64, 65, which are movable to adjust the tightness of the belts 20, 21 by means of adjusting nuts, e.g. 72, 82, engaging with threaded shafts, e.g. 70, 79. The rollers 12, 13 are each formed of annular permanent magnet discs 95 which alternate with annular steel pole piece discs 96 on a shaft 97 and held in place by end plates 100, 101. The magnets 95 may be of lesser diameter than the pole pieces providing recesses 102 which may be filled with non-magnetic material such as epoxy resin. The magnets alternate in polarity along the shaft and each magnetic pole piece of one roller at the nip region 30 is opposed by a pole piece of opposite polarity of the other roller. Instead of the drive arrangement shown in Fig. 1, the rollers 12, 13 may be mechanically synchronized by rotating them from a motor 110, Fig. 2 (not shown), through a synchronized gear train 111.
