Abstract
A magnetic screen assembly (13). The assembly (13) is to be located in a duct (10) to screen a flowable substance passing in a direction (11). The assembly (13) has a screening position (A) so that the substance passes through the screen, and a cleaning position (B) at which the screen assembly (13) is spaced outwardly relative to the housing (12) to facilitate cleaning of the assembly (13).
Claims22
A screen including:
- a base;
- a plurality of magnetic bars mounted on the base so as to be supported thereby, the bars being generally parallel and transversely spaced so as to provide an aperture between each adjacent pair of bars, each aperture having a width that extends between the adjacent pair of bars;
- and
- wherein the bars are arranged in a first set and a second set, with at least two of the bars, of at least one of the sets, each being independently moveable relative to the base in a direction generally transverse of the bars to adjust the aperture size by altering said width.

A magnetic screen assembly to be mounted in a duct along which a flowable substance is to pass so as to pass through the screen, the assembly including:
- a base to engage the duct so as to be movable relative thereto between a screening position at which the substance passes through the screen assembly, and a cleaning position at which the base is to be spaced outwardly of the duct to provide for cleaning of the assembly;
- and
- a plurality of magnetic bars attached to and supported by the base so as to extend longitudinally therefrom in a cantilever manner from the base.
A magnetic separation device including:
- a hollow body providing a chamber with an end wall, an inlet to the chamber and an outlet to the chamber, with the inlet and outlet arranged for the flow of material therebetween so that material passes through the chamber in a flow direction;
- a magnetic assembly including a base, a plurality of elongated magnets attached to the base so as to extend therefrom in a magnet predetermined direction, with at least some of the magnets terminating with a free end;
- and
- wherein said base is located adjacent said end wall so that said magnets extend into said chamber so that said magnet predetermined direction is generally transverse of said flow direction.
