Aug 12, 2001 Magnetic head pulleys replace the drive pulley on a belt conveyor and are available in diameters of 8, 12, 15, 18, 20, 24, 30, 36, and 42 inches and belt widths from 8 inches to 72 inches. A small magnetic head pulley with shaft costs approximately 1,000, while the majority of magnetic head pulleys are priced between 3,000 and 8,000.
Conveyor belt speed to remove ferrous or iron parts from a material flow, they must remain in a magnetic field for between approximately 0.3 and 0.5 seconds, where they are magnetized.To achieve maximum separation, it is important to optimally match the size of the magnet block main pole and the belt speed.
Mar 24, 2017 The In-line magnetic separator is very similar to the cross belt in that is also has a continually running belt across the magnets surface. The difference being this separator runs parallel with the conveyed material, discharging tramp meal at the end of the conveyor. Typical reasons for using this form of separator is fast running conveyors ...
For optimum separation in Position 1 installations, provision must be made to adjust the location of the magnet to suit the trajectory of the material. For Position 1 installations with conveyor belt speeds of less than 350 fpm 107 mmin, greater separation will be achieved by using a nonmagnetic head pulley.

As can be seen in Table One, cobbers are operated under greatly varying conditions, and it is difficult to determine from the table what, speed and diameter of pulley are best
DYNAMIC FERROUS SEPARATOR - DSRP MODEL US Patent US8.056.730 B2 Unlike a traditional head pulley magnet, the magnetic head pulley of the Dynamic SRP does not drive directly the belt of the separator but rotates inside a shell that rotates at a slightly higher speed than the magnetic pulley.
For magnetic particle separation and product purification, a selected plant area is determined and the feed is usually brought to this area for treatment. Magnetic separators ap-plied include I. Magnetic pulley separator 2. Magnetic drums of several types 3. Induced roll magnetic separators, high intensity 4. Cross-belt magnetic separators ...
The magnet enclosed within the separator generates a magnetic field directed towards the conveyor belt beneath. The Ferrous material is attracted by the magnet and thus removed from the material flow. The extractor belt of the separator is equipped with transversal cleats that push the attracted ferrous tramp metal towards the discharge point. Here, the intensity of the magnetic field ...
Oct 22, 2018 Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores.

May 01, 2007 An eddy current separator for scrap recovery generally has variable belt speeds and variable rotor speeds. In most instances, the rotor speed is maintained at maximum speed because the number of pole cuts per minute influences the affect on the particle. The belt speed controls the volume of material on the belt introduced to the rotor.
