The present invention lies within the field of construction materials and concerns a process for separating the constituents of hardened concrete, with the aim of extracting the cementitious fraction to be used in the production of thermoactivated recycled cement, involving the essential steps of: (a) crushing the concrete waste; (b) screening the crushed material to separate material smaller than about 1 mm; (c) fragmenting material larger than 1 mm; (d) screening material smaller than 1 mm into various granulometric fractions; (e) high intensity magnetic separation of the material; (f) grinding of the cementitious fraction resulting from the magnetic separation in the previous step to a size that allows its efficient thermoactivation; and (g) obtaining a thermoactivated recycled cement.

A magnet cleaner cooperates with one or more permanent magnets positioned over a conveyer carrying pieces of metal in non-ferrous material so as to remove the metal from the non-ferrous material. The magnet cleaner includes a frame and a capture sheet mounted to the frame and positioned on the frame so as to be substantially flush with the permanent magnets when they are in their lowered positioned. The magnets are spaced by an attenuation distance from the capture sheet when they are in their raised position. The permanent magnets, which may be mounted in a housing, are positionably mounted on the frame so as to be selectively elevatable between their lowered and raised positions upon actuation of an actuator. The actuator is positioned so as to cooperate with the permanent magnets and the frame so as to raise or lower the magnets relative to the capture sheet.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

The disclosed is a method for producing a carbon material dispersion which removes efficiently and reliably metallic components from carbon materials, and that provides a carbon material dispersion of a high product quality and stable electrical properties. The method comprises a first magnetic separation step in which the powdered and/or granulated carbon material C is applied to the surface of a rotating magnetic roll 130 to remove the metallic component M from the carbon material in the dry state of the powdered and granulated carbon material C; and a second magnetic separation step in which a magnet element 310 is placed in a carbon material dispersion D, in which the carbon material from which the metallic component has been removed in the first magnetic separation step is dispersed in a dispersing medium, in advance of the second magnetic separation step.

The invention relates to a method for separating feed material, wherein the feed material comprises at least one ferromagnetic material fraction and a non-ferrous material fraction, wherein a conveying stream is fed to a first separation of a first ferromagnetic material fraction, in particular by means of a first magnetic separating device (1), wherein the conveying stream is subsequently fed to a second separation of a second ferromagnetic material fraction from the conveying stream, in particular by means of a second magnetic separating device (2), and wherein a redistribution and/or reallocation of the material of the conveying stream takes place between the first separation and the second separation.

Provided herein are compositions comprising substrates that contain polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects, and films or inks that contain ferromagnetic materials in which the films or the ferromagnetic materials are transparent. Also provided herein are methods of fabricating the substrates. Further provided herein are ferromagnetic material films containing transparent or translucent films that comprises ferromagnetic materials. The coating imparts functionality to the film such that the film is capable of being mechanically separated from the polymeric materials or non-magnetic, paramagnetic, or diamagnetic metal objects using a commercial magnetic separator. The transparent, food-safe ink composition, which can be printed using high-speed flexographic, gravure, intaglio, offset printing or pad printing consists of an ingestible magnetically susceptible pigment capable of rendering the printed template with magnetically active properties.
