Variables and Applications on Dry Magnetic Separator
There are different methods for classifying magnetic separators, but grouping of these units based on magnetic field strength can be divided into: (1) Dry electromagnetic magnetic...A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21,22 ].Magnetic Separation SpringerLink

Influence of Separation Angle on the Dry Pneumatic Magnetic
To enhance dry magnetic separation of fine-grained materials, our research team developed the pneumatic drum magnetic separator (PDMS), an airflow-aided magnetic separator. Different positions at the separation surface of PDMS have varied separation angles, so particles at different positions may be subjected to varying The correlation between the different size fractions of the feed, e.g., − 0.6 +0.106, −0.6 + 0.211, and −0.211 + 0.106 mm and the RER magnetic parameters, e.g., belt speed and splitter angle(PDF) Optimizing the Performance of the RER Magnetic Separator

Efficient separation of iron elements from steel slag based on magnetic
In general, the change of T.Fe and P 2 O 5 content in the magnetic substances after dry magnetic separation is small. In addition, after increasing the magnetic separation intensity, more non-Fe phases are brought into the magnetic substances, resulting in more P 2 O 5 in the slag, whichThe dry magnetic separator has stable separation performance, which is mainly manifested in the extrusion magnetic system structure.
