A magnetic separator

A magnetic separator comprises a housing 10 which defines a fluid flow chamber 13 having a fluid inlet 20 and fluid outlet 30. A tube 60 is positioned within the chamber and an array 50 of magnets is positioned within the tube 60. Magnets 51 in the array 50 are separated by pole pieces 52A, 52B, 52C...

More Information
Summary:A magnetic separator comprises a housing 10 which defines a fluid flow chamber 13 having a fluid inlet 20 and fluid outlet 30. A tube 60 is positioned within the chamber and an array 50 of magnets is positioned within the tube 60. Magnets 51 in the array 50 are separated by pole pieces 52A, 52B, 52C of different lengths. Each length of pole piece causes a magnetic field of a different size/density. The magnetic field is larger, and lower density, nearest the fluid inlet 20 to attract large material from the fluid flow. Flow guides 171, 172, 173 guide fluid through the chamber 13, causing the fluid to pass between the tubes on a plurality of occasions. Material is removed from the fluid flow in a graded manner.
