Eddy Current Separator Rotor Speed

1st of 5 Technical Articles Reviewing Eddy Current Separator Performance Faster is better.  Or is it?  The magnetic rotor on an Eddy Current Separator produces the all-important separation force to recover or remove non-ferrous metals such as aluminium.  The multi-pole magnetic rotor rotates at high speeds (2000-4000 RPM) and we assess whether higher speeds produce…

Explaining Magnetic Separators

What is Magnetic Separation? Magnetic Separation is one of the most common and important physical separation techniques.  The basic concept of a Magnetic Separator is that magnetically susceptible particles or bodies are separated from non-magnetic particles.  However, the simplicity stops there.  To enable different levels of separation from a wide range materials, there is a…

Magnetic Separators For Mineral Processing

Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores.  This article investigates the use of high intensity magnetic separators in the minerals sector with a focus on processing dry materials (in the -15mm, +45 micron size range). Principles of Magnetic Separation There are three magnetic properties…

Technical Video Explanation of the Induced Magnetic Roll Separator

The Induced Magnetic Roll Separator (IMR) has been used in the non-metallic mineral industry for decades.  However, the popularity of this high intensity magnetic separator dwindled after the development of the Rare Earth (RE) Roll Magnetic Separator in the late 70s early 80s.  Whereas the magnetic forces in an IMR were electromagnetically generated, high intensity…
