Magnetic Equipments- Roll Separator


STAR TRACE was the first to introduce indigenous High Intensity, High Gradient Magnetic Roll Separator for use of dry material in Indian Market. It is capable of separating a wide variety of materials from different industries in an efficient and economical manner. It has operated successfully since 1982 in numerous production application in various countries. STAR TRACE uses high energy Rare Earth Neodymium Permanent Magnets assembled in a proprietary configuration to generate forces of magnetic attraction, which can be used for processing any material from ferromagnetic to weakly paramagnetic. The exceptionally high magnetic gradient achieved by the unique STAR TRACE design results in extremely large separation forces, exceeding those of any electromagnetic induced Roll Separators. STAR TRACE incorporates improved design features resulting from an ongoing product development philosophy combined with extensive operational experience.


A short special fabric conveyor belt envelopes the magnetic roll and a tensioning idle roll which was driven by a motor. A feeder discharges material on the belt on continuos controlled rate of flow at uniform layer thickness. The ferromagnetic and para magnetic particles adhere to the belt while the non magnetic particles flow freely off the end of the conveyor. The division of para magnetic and non magnetic can be adjusted by using a splitter plate located below the belt. It can be configurated stacked in any no of passes to suit the user requirement.


The open design of the Star Trace allows both coarse and very weakly magnetic materials to be treated successfully. Proven dry process application include material from 75 microns up to 100 mm (4 inch) particle size, at through puts from 200 kgs to 60 TPH ( depending on size).

Technical features of Star Trace Magnetic Separators are:

  • Standard 2.5,2,1.5,1,0.75,0.5 and 0.25 meter wide magnetic roll. Also available in a laboratory scale model with readily interchangeable rolls of 100mm
  • Supplied with a vibrating feeder to suit the roll width
  • Simple conveyor belt tensioning and tracking system accessible at the sides of the machine.
  • Fixed or-variable speed roll drive options. Fractional HP motor having voltage and frequency to suit user.


The design is thoroughly tested by professional staff in our well equipped laboratories. Such test work is normally conducted at no charge to potential customers. Specifications subject to change due to continuos improvement in design. Quotation for Magnetic Separator as per client.
