Magnetic head pulley

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...

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

Dry drum magnet. High speed/MGMS, permanent high intensity, alternating polarity, 75 cm diameter drum with motor, starter, housing and drive. FOB cost = 70 000 for a drum width = 75 cm with n = 0.27 for the range 30-180. L+M = 2.5. L/M = 0.45. Factors without belt, X 1.00 with in-line belt, head and tail pulley, frame, drive and motor, X 1.85 with cross-belt, X 1.87.
