Model MLH (13) 111-5 is a bottom-fed laboratory pilot plant dry high-intensity electromagnetic separator capable of separating materials having small or large differences in magnetic susceptibility. This compact separator is designed as a high-capacity alternative to isodynamic separators. It is used extensively for bench and pilot-scale testing of granular materials and in actual production situations when extracting separation of two or more high-value paramagnetic (weakly magnetic) materials from each other is required. The ‘lift type’ principle is also favored in minerals research as a magnetic assay technique for obtaining nearly pure fractions of different paramagnetic minerals to facilitate their identification and determine their weight percentage.

The bottom-fed lift type separator utilizes a vibratory feeder to transport materials horizontally through an adjustable magnetic field zone where the magnetic force acting on the particle is perpendicular upwards. A specially constructed lift type magnetic roll rotates to isolate the magnetic fraction as the paramagnetic particles are raised above the bed of moving material against gravity. Virtually no entrapment of other materials is possible with this technique.
