Embodiment Construction

[0016] The drum 1 includes a cylindrical shell 3 that can be rotated about its axis by, for example, a motor and a transmission chain. In the figure, the arrow F indicates the possible way of rotation of the drum 1. The cylindrical shell 3 has a plurality of raised contours 4, which are arranged along the longitudinal direction of the drum parallel to the drum shaft, and are used to help convey the iron adsorbed by the drum 1 on the surface of the casing 3 during the rotation of the drum. Magnetic material. The solenoids 6 and 7 are arranged in a cavity 5 closed by the cylindrical shell 3 of the drum 1, and the solenoids are connected to a continuous current power source 8 provided outside the drum. These solenoids 6 and 7 are powered by a continuous current to generate a magnetic field capable of adsorbing ferromagnetic materials on the drum 1 from the material conveyed by the conveyor 2. The material conveyed by the conveyor 2 has a small form factor, such as Equal to 2.5. ...

Abstract

The invention relates to an electromagnetic separator and a method for separating ferromagnetic materials. The electromagnetic separator comprises two or more solenoids (6, 7) which are arranged in a rotatable roller (1) and connected to a power source (8) with continuous current; and the power source (8) is used for generating a magnetic field suitable for separating the ferromagnetic materials and provides basically constant current in real time. The invention also relates to a separation method executed by the electromagnetic separator.

Description

[0001] This application is a divisional application of a Chinese patent application with an application number of 200680054987.9, an application date of June 15, 2006, and an invention title of "Separation Method of Electromagnetic Separator and Ferromagnetic Material". Technical field [0002] The present invention relates to an electromagnetic separator and a method for separating ferromagnetic materials, and particularly to a separator and a method for separating ground ferromagnetic materials including copper, thereby significantly reducing manual operations for separating them from other ferromagnetic materials. Background technique [0003] In the recovery process of the material obtained from the vehicle grinding, the "proler" process, the ferromagnetic material ground by the electromagnetic separator and separated from the non-ferromagnetic material can be advantageously reused in the steelmaking process. In the flow of ferromagnetic material from the separator, it is impor...
