A magnetic separation device includes magnetic separation units in each of which a flow direction of raw water in a separation vessel is set to the same direction as a rotation direction of a magnetic drum. In the left-side magnetic separation unit, a raw water feeding channel is connected to the left side of the separation vessel, so that the raw water flows from left to right in the separation vessel and the treated water flows out of a discharge channel. The magnetic drum rotates in a counter clockwise direction. In the right-side magnetic separation unit, the raw water feeding channel is connected to the right side of the separation vessel, so that the raw water flows from right to left in the separation vessel and the treated water flows out of the discharge channel. The magnetic drum also rotates in the clockwise direction.

A magnetic drum separator comprises a drum rotatable about an axis, the drum comprising an internal chamber and an opening at an end of the drum providing access into the internal chamber. The magnetic drum separator also comprises an inlet for supplying a liquid or granular substance into the internal chamber through the opening, a magnet outside of the drum for attracting magnetic material in the liquid or granular substance towards an internal sidewall of the internal chamber, a collection device for recovering magnetic material attracted to the internal sidewall and an annular seal member attached to the end of the drum that rotates with the drum in use. A baffle that bears against the annular seal member partially seals the opening. A plurality of cavities formed in the annular seal member receive fluid leaking into a boundary between the annular seal member and the baffle.

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.

A system for reducing dust emissions resulting from tire abrasion, comprising a collecting unit (1), arranged at a distance from the tread (4) of a tire (5) and has at least one first electromagnet and/or permanent magnet (2).
