Plate Magnets Remove Metal from Tobacco April 18, 2017
Plate Magnets are used in tobacco processing to remove metal contamination introduced from collection and transportation of tobacco leaves, or in the process. The Metal Contamination can be large in the form of a nail or bolt, or as small shards. Metal can damage delicate processing equipment such as the blades on the tobacco leaf cutter, which can prove to be very costly.
Plate Magnets are available in two magnet strengths. Standard Ferrite or Ceramic Plate Magnets are suitable for larger tramp metal. However, for removing metal from tobacco, higher strength Rare Earth (Neodymium Iron Boron) Magnets were required. These produce exceptionally strong magnetic fields and capture very fine magnetic particles.
Although many Plate Magnets are installed in chutes, these models for this tobacco installation were mounted above the conveyors. Metal contamination is magnetically attracted up off the moving conveyor and onto the face of the Plate Magnet. The amount of metal captured by the Plate Magnets was substantial.
Each Plate Magnet had a Flat Face and was designed to be Self-Cleaning. They were also supplied with a mounting kit and removable lever.
The specifications of the Plate Magnets supplied were:
31 Rare Earth (Neodymium Iron Boron) Plate Magnets with 165mm (6.5") deep magnetic field;
38 Rare Earth (Neodymium Iron Boron) Plate Magnets with 125mm (5") deep magnetic field;
29 Rare Earth (Neodymium Iron Boron) Plate Magnets with 90mm (3.5") deep magnetic field;
Plate Magnets are one of many designs of Magnetic Separators used in the process sector. The type of Magnetic Separator is dependent upon the application and the type of metal contamination.
