Operating Principle of Magnetic Drum Separator

EZ Drum Separators are primarily designed and manufactured as low field intensity separators. They have an open magnetic system with the magnetic poles located in one plane. Low field intensity separators are employed for separating iron particles from bulk material whenever foreign iron disturbs the subsequent process sequences. It is also used for removing or enriching strongly magnetic content of dry minerals.

The most widely used application of drum separators is by deflection separation in which the bulk material is fed onto the top of the drum. This must be spread evenly over the entire width in order to ensure optimum utilisation of the drum. The use of a vibratory feeder is appropriate for feeding the material tangentially onto the drum. This operating procedure ensures minimum wear to the outer drum and guarantees constant-speed application. At normal feed speed of 0.2-0.3 m/sec. using vibratory feeders, the material is spread and distributed quickly over the drum, which rotates at a speed of 0.6-0.8 m/sec. The material is reduced to 1/3 - 1/4 of the feed layer height.

On permanent drum separators rectangular magnetic blocks generally made of sintered hard ferrites are radially magnetized and mounted on a soft iron plate.

The magnetic drum is connected to a rigidly fixed shaft, the position of which is adjustable. The outer drum made of high-grade steel or manganese steel rotates around the axis supported on roller bearings.
