Choosing the Right Permanent Crossbelt Magnets for Recycling

Crossbelt (overband) magnets, a staple in recycling operations, play a crucial role in retrieving ferrous metals and safeguarding shredders from harm. Bunting offers a diverse selection of designs tailored to the specific needs of customers in the recycling industry. Understanding each installation is crucial in choosing the right crossbelt magnet to maximize the performance of your operation.

Crossbelt Magnets are the Backbone of Recycling

Dating back to the early 1980s, Bunting has pioneered the creation and evolution of permanent crossbelt magnets for recycling. We have delivered countless units worldwide. While the fundamental technology remains the same, advancements in materials and manufacturing techniques have notably boosted ferrous metal separation efficiency.

Crossbelt magnets efficiently lift and recover ferrous metals from conveyed waste using a permanent magnet block mounted within a frame, alongside two or four pulleys and a revolving self-cleaning rubber belt. During operation, the conveyed recycled waste passes beneath the crossbelt magnet, where it attracts, lifts, and subsequently eliminates harmful tramp ferrous metal. The selection of the magnetic system, whether Permanent or Electro, is determined by factors such as conveyor width, material depth on the conveyor, and the characteristics of the tramp ferrous metal.

Custom Solutions

Permanent crossbelt magnets are commonly found in various settings, from mobile recycling plants to smaller installations. Bunting offers a range of models to suit diverse applications:

• The Light Duty Magnetic Crossbelt Separator is a lightweight and compact solution that is most commonly used to separate ferrous metals from plastics or electronic recycling applications.  

• The Standard Duty Magnetic Crossbelt Separator is used in a wide range of recycling facilities. Available in three reachout strengths, this crossbelt separator is used in recycling processes for wood, plastic, metal, rubber, electronics. MRF, and more.

• The CBS MAX Heavy Duty Magnetic Crossbelt Separator is a rugged, heavy-duty piece of equipment that is specifically designed to handle the high demands of the Automotive Recycling Industry.

• Electromagnetic Crossbelt Separators can be used both for the Recycling industry and for the Aggregate, Mining & Minerals industry. These models are the most powerful crossbelts in Bunting’s line, and can work at the increased operating gap necessary to extract ferrous material from deep troughed conveyors. These include the ElectroMax crossbelt, the OCW Heavy Duty Oil-Cooled crossbelt, and the ACW Heavy Duty Air-Cooled crossbelt.

Selection Process

Choosing the right crossbelt magnet, whether Permanent or Electro, depends on understanding the application’s nuances. Bunting’s application engineers meticulously evaluate factors such as ferrous metal separation goals, the characteristics of the metals involved, and the conveyed waste’s size range and depth. This informed approach ensures the selection of the optimal crossbelt magnet for each recycling application. With decades of expertise in crafting magnetic solutions tailored to recycling needs, Bunting remains at the forefront of innovation, providing customized and effective separation solutions.
