Abstract:
1. A high gradient magnetic separator ( 1 ) for the selective separation of magnetic particles from suspension, comprising a housing ( 5 ), a matrix forming a separation zone disposed in said housing ( 5 ), the housing ( 5 ) having an inlet area ( 4 ) for supplying the suspension to said matrix and an outlet area ( 12 ) for discharging the suspension from said matrix, said matrix consisting of alternately arranged spaced stationary and rotatable plate separation structures ( 13 , 14 ) of magnetic material with spaces formed there between through which, the suspension including the magnetic particles is conducted, said stationary plate separation structures ( 13 ) supported by said housing ( 5 ) forming a stator and said alternate rotatable plate separation structures ( 14 ) being mounted on central rotatable carrier shaft ( 8 ) forming a rotor with passages arranged between the stationary plate separation structures ( 13 ) which are mounted to the housing and the rotatable plate separation structures ( 14 ) which are mounted to the rotatable shaft ( 8 ) being disposed in the flow path between the inlet area ( 4 ) and the outlet area ( 12 ) so that the suspension must pass through at least one of said passages, said matrix being disposed within a magnetic system ( 2 ) capable of magnetizing the plate separation structures ( 13 , 14 ) of magnetic material.
