Abstract: Since Thomas Edison invented the magnetic roller separator for concentrating nickel mineral, drum and roller type separators have become the most common magnetic separators. These devices can be constructed with permanent magnets or with electromagnets, and the drum separator can operate with a dry or wet supply. However, still today, strongly magnetic material detaching from the roller is a problem that has been tried to be resolved by introducing the magnets inside the cylinders, in only one area thereof, in such a way that when the material is rotated on the cylinder and moves away from the magnetised area, it falls as a result of gravity. This system has a highly complex structure. The invention uses novel and powerful, very small neodymium magnets to cover the entire surface of the roller. In this way, a small device with a larger yield is produced in a very simple and economic manner. The particulate material to be separated is supplied over a plastic piece covering the magnetic roller that is in contact with same only over a fraction of the circumference, such that when the plastic piece moves away from the magnetic roller, the material falls as a result of gravity and is separated from the rest by means of a deflector.

Abstract: A method and apparatus for removing metallic material from a circulating well fluid stream provides a treatment vessel that is divided into first and second sections. Each of the sections includes a magnetic field that can be in the form of one or more magnets. In one embodiment, multiple magnets are provided in each of the sections. Manifolds attach to an influent and to an effluent of the treatment vessel. Each manifold enables selective transfer of fluid to either of the selected sections. Similarly, discharge of circulating fluid can be from either of the sections via a discharge manifold. The treatment vessel enables continuous treatment by valving fluid flow so that only one section need be used at a time in order that the other section could be serviced for removing collected metallic material from the magnetic field or from the magnets.

Abstract: A machine for collecting tie plates strewn along a rail bed includes a frame adapted for travel along a railroad in a forward direction. A pickup drum having magnetic properties is rotatably supported by the frame and extends over a bed portion of the railroad. A top drum is mounted at a location that is higher and forward of the pickup drum and rotates parallel to the pickup drum. An endless conveyor circulates around the pickup and top drums, and a separation drum is disposed between the pickup drum and the top drum along an ascending portion of the endless conveyor. The separation drum includes a magnetized rim that can lift ferrous objects but not tie plates from the endless conveyor.
