Working Principle & Magnetic System :
The Permanent Magnetic Drums consists of a stationary Permanent magnetic assembly having uniform and everlasting Magnetic field accross the entire width of the drum, which is effective over approximately half the drum circumference as shown in Fig-1. Drum shell made of non Magnetic stainless steel revolves around the magnetic field. As the material fed evenly from the chute falls over drum, powerful magnetic field attracts and holds ferrous particles to the revolving shell. As the revolving shell carries the Iron particles through the stationery magnetic field the non-magnetic material falls frelly from the shell while ferrous particles are firmly held until carried beyond devider and out of magnetic field.
The strength of the permanent magnetic drum is guaranteed to be greater than corresponding electromagnetic drum. The Permanent magnets used are everlasting magnents and its strenght does not diminish during normal use and can be used through.

Ferrite Magnet
The magnetic separator with ceramic magnet is useful for the application where free and larger iron particles are to be separated. The average magnetic intensity on the magnetic drum surface will be 1500-2000 Gauss.
Rare Earth Magnet
The magnetic separator with high intensity Rare Earth NdFeB (Neodymium- Iron- Boron) magnets are useful for removing magnetic contamination with low magnetic properties and fine iron particles are to be separated. The average magnetic intensity on the drum surface will be 3500 - 5500 Gauss.
