Detailed product description

Design

Magnetic head pulleys (or head roller magnets) are made in standard sizes and can therefore be easily integrated into an existing installation. The shaft diameter, for example, is suitable for SNL bearing blocks, and the shaft journal (including keyway) is suitable for a standard SEW gear unit.

Magnetic pulley/head roller for the bottom layer

These are global standards and therefore cover most applications. The modular design makes it easy to replace the shaft, which is ideal for maintenance and customer-specific solutions.

Various versions available to meet your needs:

  • for belt width: 400-2000 mm;
  • diameters: 150-400 mm;
  • magnet system: both axial and radial magnet construction possible.

Types

There are four types of add-on magnetic head pulleys, each with its own application. The use of different magnetic materials, such as ferrite or neodymium, influences the magnetic field. Another important determining factor is the construction of the magnetic system, which can be either axial or radial.

Type F = Ferrite 1800 gauss

  • cost effective
  • separation of pieces of ferrous metal from 1 to 100 mm
  • shell thickness 2 mm
  • magnetic field depth 100 mm
  • axial magnet construction
  • ferrite magnet (1800 gauss at the shell)
  • not suitable for separation of weakly magnetic metal particles

Type B = Neodymium 3000 gauss

  • separation of pieces of ferrous metal from 0.5 to 100 mm
  • shell thickness 4 mm
  • magnetic field depth 100 mm
  • axial magnet construction
  • ferrite/neodymium magnet (3000 gauss at the shell)
  • not suitable for separation of weakly magnetic metal particles
3000 gauss head pulley magnet field

Type P = Neodymium 6000 gauss

The 6000 gauss neodymium magnetic head pulley has an axial magnet construction and, with its high magnetic force, is suitable for separation of paramagnetic and weakly magnetic particles from thicker material layers, such as stainless steel processed by a shredder or iron dust in the micron range from ceramic materials. These have slightly magnetic properties and can therefore be separated in this manner.

This head roller magnet also removes very fine (ferromagnetic) metal particles from ceramic powders and glass fractions.

  • separation of weakly magnetic particles > 0.5 mm
  • separation of ferrous particles > 0.1 mm
  • shell thickness 5 mm
  • magnetic field depth 150 mm
  • axial magnet construction
  • ferrite/neodymium magnet (6000 gauss at the shell)

Type H = Neodymium 9000 gauss

The 9000 gauss neodymium head roller magnet separates weakly magnetic particles (such as stainless steel processed by a shredder) or paramagnetic particles from certain soil contaminants (such as insect poop, soil or pebbles). This high-gradient head roller magnet is used for thinner layer thicknesses than the 6000 gauss magnet and is only used for removing ferrous particles when they are sporadically present in the product flow.

  • separation of weakly magnetic particles > 0.1 mm
  • separation of ferrous particles > 30µm (sporadic)
  • shell thickness 1 or 2 mm
  • magnetic field depth 30 mm
  • radial magnet construction
  • neodymium magnet (9000 gauss at the shell)
