In order to give product a good
quality base, it is must that all the impurities should be removed from
the basic raw materials. Various types of raw materials are used for
making glass and plastics. These raw materials are first cleaned by
subjecting them to various types of magnetic separators that pulls
ferrous fines and other contaminants from the raw materials and made
them fit for production of final goods.
Disc Separators
In disc type of separator feed material is discharged to a vibratory
feeder tray, from a hopper. Transportation of the materials take place
beneath the rotating discs. Magnetic particles after reaching the
magnetic field of the disc gets attracted to the high gradient magnetic
zones on the discs. The captured particles are carried to the discharge
chutes by the rotating disc. The secondary and final separation of the
materials take place in the second and the third zone of the machine and
then finally the cleaned materials are discharged out of the machine.
Induced Roll Magnetic Separator
In induced magnetic roll separator, material being treated is fed from
a hopper or vibratory feeder at a controlled rate onto a high intensity
magnetic roll. The magnetic particle present in the materials attach
themselves onto the roll face whereas non magnetic material is thrown
off the face at a normal trajectory.
Rare Earth Roll Separators
Rare earth roll separators consist of the most powerful rare earth
permanent magnet like Neodymium Iron Boron magnets thereby transforming
it as a high intensity and a high gradient separator. These separators
can extract both ferromagnetic and paramagnetic materials. This enables
the separator to create a cleaner product with no metal contamination.
