ABSTRACT:
An improved magnet configuration of the magnet field generated by the magnetic roller in a magnetic separator to increase the separation capability of magnetic separators includes disc shaped magnets forming a magnetic roller beneath a Kevlar.TM. belt upon which withdrawn catalyst is placed. Catalyst particles having paramagnetic and/or ferromagnetic properties are attracted to the belt because of the influence of the magnetic field. Particles not having ferromagnetic and/or paramagnetic properties are carried further by momentum than those with the ferromagnetic and/or paramagnetic properties. The magnetic roller provides a concentrated magnetic field by placing a series of disc magnets arranged so that like poles face each other with spacers placed between the magnets. In this stacked configuration the magnetic field strength is doubled, which permits a greater range of operation of the speed at which the belt may be operated.
