Drum magnets can be supplied as the drum only (so they can be incorporated into a customer’s existing machine or process), and can also be supplied in a completely enclosed housing. Bunting recommends housing when there is the need to retain dust within the system or a chance of external contamination.
Housing are also useful for keeping the material contained and to ensure the material is passed closely over the drum cover.
Housings are manufactured in robust mild steel or stainless steel depending on the magnetic field and the application. Bunting provides inspection covers, aspirators, and diverter plates standard. Bunting engineers will often work with customers to design bespoke housing to suit specific installations. Open topped housing options are available for larger bulkier materials, or where the vibratory feeder tray needs to fit down right over the top of the drum for a smoother stream transition.
Applications
Permanent drum magnets remove ferrous and weakly magnetic particles from dry non-magnetic material in many different applications and industries. They can be found in the food processing industry to remove fine metal fines out of the product stream, recycled plastic and PET industries to remove ferrous contamination, auto – electronics – rubber recycling, and mineral processing, as well as many others. We also offer the larger electromagnetic drum magnets for the Auto and Metal Recycling Industries for the larger metal fraction sizes.
