The Slag Electro Drum Magnet, or SED, features two or more symmetrical coils (depending on width) that produce a continual radial pole.
The magnet system on the SED was specially designed by our engineers using computer design software in order to maximize efficiency. This magnet system consists of a mild steel core that is wound with anodized aluminum foil. While the covers rotate, the magnet system itself remains stationary. The 2, 3, or 4 coil, continuous pole design, is made up of coils that concentrate maximum flux at the point of extraction. At the same time, an extension pole ensures that magnetic material is carried around the drum where it reaches the point of discharge. By arranging poles radially over the width of the drum, the highest level of separation is achieved and maximum entrapment of metals is ensured as a result.
Additional features of the SED include:
• Main shell cover with robust construction. The shell cover is fabricated from 8mm thick wear-resistant manganese steel which is fully welded to the end flanges.
• Wear cover: Similarly constructed from 8mm thick wear resistant manganese steel, this wear cover has bolted joints that allow ease of replacement. On the wear cover, there are wiper bars fitted across the whole width of the shell, as well as at regular intervals around the drum shell’s circumference.
• Low carbon steel end flanges have one end fitted with an inspection cover, facilitating easy visual inspection of the coil and windings.
• Copper split flange bearings allow easy maintenance.
• Fixed bearings: Pedestal bearings with locking rings clamp the magnet securely in its working position.
• Easy Adjustment: An adjuster arm makes it easy to adjust the position of the magnet system within the drum, and this arm is fitted with a turnbuckle and cone locking ring. The customer may set the magnet position and thus the discharge of ferrous metals in accordance with their discharge chutes, which ensures maximum separation efficiency.
• Drive: A BS Pitched Simplex platewheel is bolted to a robust drive ring.
• Power Supply: 380/415v, 3ph, 50Hz or 230/460v, 3ph, 60 hz.
• Finish: Steel is finished with one coat of primer and two coats of RAL high performance alkyd enamel.
