A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.

A workpiece processing assembly comprising including a media collection device that is adapted to receive used media from a media blasting chamber. A transport mechanism, coupled to the media collection device, transports used media to a media reclaim system. A first separation device is used to perform a filtering process on the used media to separate non-usable media from usable media. A second separation device is configured to apply a magnetic field to the usable media to create recycled media for use in the media blasting chamber.

A tramp metal removing device has a primary housing to define a product flow path for being passed by a stream of raw materials and a moving path. A secondary housing is connected to the primary housing. A plurality of drawer units are sequentially stacked on the primary housing and secondary housing. Each drawer unit has a frame, a plurality of magnetic members and a scraping assembly. The frame is coupled with the primary and secondary housings in a movable way. Each of magnetic members is secured on the frame and has a magnetic section and a non-magnetic section. The scraping assembly is coupled with the frame in a way that it is only moveable in the secondary housing for removing tramp metals of a stream of raw materials in a two-stage manner.

A pneumatically-operated magnetic separator captures magnetic contaminants from process fluids. Process fluids are used in many industrial operations for various purposes. The pneumatically-operated magnetic separator can include a housing wall, a first flange plate assembly, a second flange plate assembly, a main fluid passage, tubes, and shuttles. The first and second flange plate assemblies can each include a pair of flange plates. The tubes extend between the first and second flange plate assemblies, and the shuttles are situated in the tubes. Each of the shuttles includes one or more magnets. During use, the shuttles move longitudinally in the tubes in response to pneumatic actuation and de-actuation, per an example. Weldments attach the tubes and the first and second flange plate assemblies together.

A magnetic particle manipulating apparatus includes a magnetic force source moving mechanism, an operation controller configured to control operation of the magnetic source moving mechanism, an openable cover for covering the device holder, a pressing mechanism provided on the cover to press the tubular device held by the device holder when the cover is closed so that warpage of the tubular device is corrected, an open/close state detector provided so as to detect an open/close state of the cover. The operation controller is configured to execute the processing operation only in a case where the open/close state detector detects that the cover is closed.

A device for separating tramp metals from liquid raw materials includes a body unit, a holding unit, a magnetic unit, a rinsing unit, and a driving unit. The body unit includes a tank for feeding-in and feeding-out liquid raw materials. The holding unit is coupled to the tank and includes and a plurality of non-magnetic holders received in the tank. The magnetic unit is mounted on the tank and includes an enclosure haying a telescopic wall to be in a compressed or extended state. The rinsing unit is fixed on the interior of the tank to rinse the non-magnetic holders. The driving unit is coupled the tank and the magnetic unit for driving the magnet unit moving between a first and second positions. An assembly is assembled from the device. And a method is carried out by the device or the assembly.

A magnetic tool may be provided with a ditch magnet that may include end plates (or handles) having a mostly open architecture, and these end plates may be permanently affixed to the ends of the magnetic bar. Ferrous metal may pass through by urging captured ferrous metal from one end of the ditch magnet to the opposite end. The captured ferrous metal may be urged from one end of the ditch magnet bar to an opposite end using a composite, multi-component wiper. The wiper may remove captured ferrous metal safely and effectively from the ditch magnet bar.
