摘要： A magnetic drum separator is provided. The drum separator includes a drum and a pulley arrangement that rotates the drum. The drum separator includes an end plate coupled to the drive assembly, and the drive assembly rotates the end plate with the drum. The end plate includes a radially oriented slot. A plurality of magnets is disposed in the drum, and the magnets are attached to the end plates and rotatable with the drum. A cam assembly is disposed in the drum and remains stationary during rotation of the drum. The cam assembly includes a cam with a cam track formed therein. The magnets have a cam follower located in the cam track and an end plate follower located in the slot of the end plate. The cam track and the radially oriented slot guide the plurality of magnets to move radially inwards and outwards as the magnets rotate.

摘要： 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.
