Stainless Steel Separators

The Stainless-Steel Magnetic Separator is unique.  Bunting engineers designed a patented Neodymium Rare Earth magnetic roll that produces an ultra-strong magnetic force to attract even the weakest magnetic materials.  The strength of the magnetic field is far greater than standard magnetic separators, extending the separation capabilities from just removing ferrous and strongly magnetic materials to materials that have a very low magnetic susceptibility.

The two models – the High Intensity Separation Conveyor HISC and Stainless-Steel Separation Conveyor SSSC – are designed to handle different particle sized materials.  The HISC model is successfully used in smaller particle recycling applications such as copper wire, WEEE and plastic waste.  The SSSC model is designed for larger fragmented stainless steel as found in car shredding plants.

Description

The Stainless-Steel Magnetic Separator is a revolutionary and patented ultra-high intensity metal separator.  Bunting engineers used Finite Element Design software technology to develop two different magnetic rolls capable of separating the most difficult weakly magnetic materials.  The magnetic rolls use the strongest permanent magnets presently available – neodymium iron boron rare earth magnets.

Model HISC – High Intensity Separation Conveyor

Designed for the separation of smaller weakly magnetic particles between 10 and 50mm (1/2”–2”) :

  • Two standard pulley diameters – 100mm (4″) and 150mm (6″) diameters;
  • Stainless frame discharge ends to prevent magnetic inducement from the extreme magnetic fields;
  • Heavy duty formed 5mm frames;
  • The frame features forklift lifting slots for easy placement and relocation;
  • Heavy duty formed 5mm sideguards over the flexwall belt to seal off and contain the material flow;
  • Tough urethane belt;
  • Optional belt lengths for the addition of Permanent Overband Magnets or Plate Magnets to remove strongly magnetic materials;
  • Optional variable frequency drive to optimise separation for belt speeds between 18 and 60 metres per minute;

Model SSSC – Stainless Steel Separation Conveyor

Developed to separate larger fragmented stainless steel between 25 and 125mm (1-5”):

  • 200mm (8″) pulley diameter;
  • Patent-pending magnetic core design;
  • Unique high-intensity gauss grid design generates ultra-high magnetic forces;
  • Stainless frame discharge ends to prevent magnetic inducement from the extreme magnetic fields;
  • Heavy duty formed 5mm frames;
  • The frame features forklift lifting slots for easy placement and relocation;
  • Heavy duty formed 5mm sideguards over the flexwall belt to seal off and contain the material flow;
  • Tough urethane belt;

Operation

In operation, a controlled rate of material is fed via a vibratory feeder onto the belt of the Stainless-Steel Separator. The material is conveyed into the magnetic field produced by the Rare Earth Head Roll where weakly magnetic material is attracted, held or deflected, and then deposited underneath. Non-magnetic material is unaffected and flows in a normal trajectory. A strategically placed splitter enables separate collection of the two fractions – magnetically-susceptible and non-magnetics.
In some applications, a Permanent Overband Magnet or Plate Magnet is positioned over the conveyor to remove strongly magnetic or ferrous metals before entering the ultra-strong magnetic field.
