magnetic separation
electromagnetic pulleys
For certain applications such as iron ore cobbing, slag processing, mineral beneficiation, etc., successful utilization requires that the field strength of the magnets be regulated to compensate for various factors that can change recovery and grade of values in the product. For these applications, Walker Magnetics offers Electromagnetic Pulleys rather than the permanent magnets described above. In addition, Electromagnetic Pulleys come equipped with a Variable Voltage Control Rectifier which can be remotely mounted at the most convenient work location. Walker Electromagnetic Pulleys are available in the same wide range of diameters and belt widths as Walker Permanent Magnet Pulleys, and in addition, offer a choice of 115 or 230 VDC aluminum or copper coils.
