Problems solved by technology

Since this effect causes an increase in electrical resistance and energy loss in the power transmission line, the magnetomotive force generated by the solenoid is significantly reduced, reducing the collection efficiency of the ferromagnetic material

Embodiment Construction

[0016] The drum 1 comprises a cylindrical shell 3 which can be rotated about its axis by eg a motor and a drive chain. In the figure, the arrow F indicates possible rotations of the drum 1 . The cylindrical shell 3 has a plurality of raised profiles 4 arranged along the longitudinal direction of the drum parallel to the drum axis for helping to transport the iron absorbed by the drum 1 on the surface of the shell 3 during the rotation of the drum magnetic material. Solenoids 6 and 7 are arranged in a cavity 5 closed by the cylindrical shell 3 of the drum 1 , said solenoids being connected to a power supply 8 of continuous current provided outside the drum. These solenoids 6 and 7, powered by a continuous current, generate a magnetic field capable of attracting ferromagnetic materials to the drum 1 from the material conveyed by the conveyor 2 having a small form factor, e.g. Equal to 2.5. The north pole N of the magnetic field generated by the solenoids 6 and 7 is close to t...

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