Working of Magnetic Roll Separator:

The Magnetic Roll Separator has two rolls of which one does not contain magnets where as the other has magnet embedded in the roll. The two rolls are wrapped by conveyors belts over which the feeds travel for separation. Upon crossing over the magnetic roll, all the magnetic substances stick to it till they are relieved from the magnetic field. Non magnetic substances fall freely from the Magnetic Roll Separator where as those reacting to the magnetic field fall further away. If multiple rolls are installed separation takes place at each level and a purely magnetic output is derived.

The material to be processed is conveyed to the belt by vibrating feeder at a required rate. Feeding rate can be controlled by adjusting the vibration on feeder. A Roll separators blade has been set in order to be able to collect separated products in different places and to adjust the product properties in a desired manner.

Technical Significance of Magnetic Roll Separator:

  • Feed rate 2.5 tph, feed temperature has an impact on magnetism
  • By making adjustments in pulley and belt the roller speed can be changed.
