［Application］
These separators are suitable for separation of weak magnetic substances that exist in powder and
granular materials of quartz sand (glass material), high grade casting sand and chromite sand. In addition,
these separators are used to remove iron ores from such nonferrous minerals as tungsten, manganese ore,
titanium ore, monazite, garnet and ilmenite, to remove weak magnetic oxides from casting sand (quartz
sand) and to separate weak magnetic substances from other powder and granular materials.
［Features］
●The induction roller generates 2.6 T (Tesla) max. at a sharp gradient and high magnetic flux density.
●The magnetic force can easily be adjusted according to magnetic substances in raw materials.
●The roller revolution can be varied steplessly. According to properties of raw materials, the influence of the
centrifugal force by the roller can be adjusted for optimum separation. (Optional)
●When the 2-stage or 3-stage type is used, highly effi cient separation is possible.
●These separators are of dry type that does not need auxiliary equipment for pre- and post-treatment.
●These separators are designed to contain dust to prevent pollution by dust.
Processing conditions
Optimum substances to process are materials that are dry and flow freely and their grain size is 8 to 150 mesh.
Capacity
The amount to process is about 200 kg/h to 1000 kg/h per induction roller width 100 mm, though it varies according to
kinds and grain sizes of substances to separate and required level of separation.
One-stage or 2-stage according to applications
Because a high magnetic force is required, the magnetomotive force is induced by the roller by use of a yoke so that
weak magnetic substances can be separated from flowing raw materials. The figure shows the 3-stage type. Onestage, 2-stage and 3-stage are determined by the number of induction rollers.
