Abstract

A rotatable magnet cradle assembly that can be used to separate swarf from a flow of fluid is provided. The cradle of magnets can be rotated a certain amount about a rotational axis from an operational position to a cleaning position. The magnet cradle may include a tube extending between two brackets, a shaft to which the two brackets are attached, and a magnet bar extending through the tube. In the operational position, the magnet provides a magnetic field that attracts swarf to an outer surface of the tube. Once it is desired to clean the assembly, the shaft is rotated to move the two brackets and tube out of the fluid flow and to a position proximate a discharge location, where the magnet bar can be removed from the tube to release the swarf.
