Mar 01, 2017· The influence of particle size on a magnetic fraction of Induced Roll Magnetic Separator was analysed as theD 50 (μm) and D 80 (μm) size.The results show that segregation of the coarser particle is segregated in non-magnetic fraction while finer sized particles are at the magnetic fraction.
Feb 01, 2020· Once the optimal particle size fraction was obtained, wet magnetic separation was performed using this fraction to increase the REY enrichment. Coal fly ash was first mixed with water at a liquid-to-solid ratio of 4:1 (mL/g) and then placed into a wet magnetic separator. Magnetic flux densities of4300 G and 10 800 Gwere applied.

In addition, Chen and co-workers filled up their magnetic separation chamber with irregular-shaped iron particles with diameter rangingfrom 25 to 75 µm,in order to generate highly localized and strong magnetic field gradient upon exposure to an external magnetic field to allow the effective separation of HIV virions that had been labelled with magnetic particles .
Industrial Screening. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016. Industrial screening is extensively used for size separationsfrom 300 mm down to roughly 40 µm,although the efficiency decreases rapidly with fineness. Dry screening is generally limited to material above ca. 5 mm in size, while wet screening down to ca. 250 µm is common.
