Features

1. The magnetic system of the magnetic roller adopts the NdFeB magnet with high magnetic energy product and high coercive force, which has high magnetic field strength and great action depth.

2. The rate of demagnetization of magnetic field intensity for 8 years is not more than 5%.

3. The magnetic system is not attached to the magnetically conductive stainless steel to ensure that the magnet does not fall off.

4. The magnetic drum body by magnetic stainless steel and wear-resisting rubber tube, greatly prolongs the service life of.

5. The permanent magnetic roller can do both the active drum and the driven roller. 

Working principle

When ores go through the permanent magnetic drum, the non-magnetic and low-magnetic particles will leave the belt surface because of the centrifugal force and gravitation. Meanwhile, strong-magnetic particles are absorbed to the belt by magnetic force and then fall into the magnetic trough when the belt leaving the magnetic pulley.
