Magnetic Pulleys. Magnetic puUeys of special design are used in the concentration of magnetite and other ferromagnetic minerals. For best results, the feed should be screened into various-sized fractions and each fraction treated on a separate puUey separator unit. Typical feed size is 100 X 50 mm, 50 x 25 mm, and 25 x 6 mm. When treating material of —10 mm, an axial pole magnetic puUey should be utilized, as this provides uniformity of field across its width. 

Drum and Pulley Magnets Since Thomas Edison invented and developed the magnetic pulley for the concentration of nickel ore, drums and pulleys have become the most common types of magnetic separators. These devices can be built with either a permanent magnet or an electromagnet, and the drum separator can operate with...

The most common magnetic separators used in solid waste separation and recycling are head pulley magnets, magnetic drums, and suspended belt magnets. 

Magnetic Head Pulley. This equipment uses the principle of magnetic particles pinning on the carrier, which carries the particles into the magnetic field (see Figure 17). After separation, ferrous metallic and nonmagnetic particles are carried onto conveyor belts and, subsequently, to bins or hoppers. This...
