The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin. The magnetic element design affords the maximum field gradient and the 5 poles enables additional cleaning of the magnetic stream. This gives a very selective separation at high throughputs compared …

It is well known that, in the magnetic separation of magnetic particles, the dominant force that differentiates magnetic particles from nonmagnetic particles is the magnetic force F ⇀ m, which is given by Svoboda and Fujita (2003): (1) F m ⇀ = κ μ 0 V B ∇ ⇀ B where κ is the volumetric magnetic susceptibility of magnetic particle, μ ...

Abstract. Separation of microparticles and cells serves a critical step in many applications such as in biological analyses, food production, chemical processing, and medical diagnostics. Sorting on the microscale exhibits certain advantages in comparison with that on the macroscale as it requires minuscule sample or reagents volume and thus …

Using a high magnetic field (0.56 T) and 1 h mixing time, fluorescence and ICP-OES data showed approximately 85–100% oil and NP removal under most conditions, with the higher magnetic field and the presence of SS wool giving significantly improved separation of both oil and NPs. However, only a fraction of the NPs were used in oil …

3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.

The magnetic hydrocyclone was developed as a natural extension of a conventional hydrocyclone with the aim of providing additional external magnetic force to supple-ment the gravitational and centrifugal forces that cause classification and separation. By providing such an external force, it is possible to manipulate the separation more
