Our Partners


MPI, based in southeastern Michigan, is a worldwide provider of both magnetic and non-magnetic material handling solutions. MPI leads the industry by continuously engineering inventive magnetic equipment and advancing customer education, though significant investments in research and development and proactive product training.

MPI’s first goal was to improve the performance of permanent magnetic separators. Within five years, MPI was to implement dramatic changes in equipment design that remain in place today. As a result of MPI’s engineering and development, easy-to-clean manually operated permanent magnets and self-cleaning automatic permanent magnetic separators are common worldwide. MPI is proud to have set the industry standard for permanent magnet separator equipment design and performance.

Going forward, MPI will continue its tradition of advancing product performance and expanding its line of metal control systems and material handling equipment solutions. By interacting closely with its customers and focusing on a market-driven product line, MPI has positioned itself to readily meet the challenges of today’s dynamic global economy.

Main Products


Powerful permanent magnets are conveyed below a nonmagnetic stainless steel slider bed to move and convey ferrous metal objects. The liquid-tight, sealed conveyor housing can be completely submerged in machine reservoir tanks and the internal self-adjusting take-up system eliminates the need for maintenance. No external moving components make the beltless magnetic conveyor the safest way to convey ferrous metal parts and scrap.


Traditional magnetic separation equipment has been “dumb”, operators have to shut down their equipment and check them at set intervals. Intell-I-Mag is the first magnetic separator that is “intelligent”. It tells you when the magnet needs to be cleaned, or, just as important, when it doesn’t.

The Intell-I-Mag monitors tramp metal saturation levels on the working surface of the magnetic separator in real-time. The magnetic separator has sensors embedded into the separator that measure the strength of the magnetic field. These sensors report data collected in real-time to a controller.

The controller can be programmed to alert operators when the separator reaches user defined saturation levels so they know when the magnet needs to be cleaned.

Industry Applications


Primary magnets are designed to be used in high volume process flows placed inline so as not to introduce any foreign contaminants from external sources into your production facility. They will remove large amounts of ferrous tramp between cleaning cycles giving you peace of mind. These magnets are typically located in plant receiving areas and handle large amounts of materials that tend to damage equipment or bridge in many magnet applications. The magnet circuit design is such that the magnetic field reaches out is maximized while maintaining adequate holding values to gather large amounts of tramp before reaching the saturation point. Primary magnets help to identify risks associated with bringing in ingredients from outside sources allowing you to monitor your vendor product quality.


Secondary magnets are used in processing areas in front of sensitive pieces of equipment for protection, as well as throughout your process for redundancy which helps to detect process equipment malfunctions. The material flow is typically metered at this point, which enables us to specify your exact application requirements. The magnetic circuits are designed with specific functions, whether that be to maximize the magnetic fields reach out, holding force, or a combination of both.


The function of a finishing magnet is to maintain your end product quality to your customer. Finishing magnets capture small metal fines from your process ensuring product shipped from your plant, whether going to another manufacturer for further processing or to a shelf for consumer use, contains no ferrous tramp contamination. This protects your brand reputation and financial liability for recalls, as well as consumer protection.

Components and Functionalities


SR separators are typically used as head pulleys in belt conveyors. As tramp metal nears the separator’s magnetic field, it is attracted and held to the conveyor’s belt until it reaches the underside of the conveyor, where it passes out of the magnetic field and discharges into a chute or bin. The cleaned, contaminant-free material discharges from the top of the conveyor, away from the tramp metal.

  • Powerful Ceramic 8 permanent magnet material
  • Stainless steel face
  • Rugged, all-welded construction
  • 3 different magnetic circuits available
  • Face widths from 8” – 62”
  • Roll diameters from 4” – 36”


Our lift magnets utilize high energy Neodymium magnets offer tremendous lifting capacity when handling flat, round and cylindrical material. The Easy Switch system activates the magnet On and Off simply — using just one hand with a significant time savings! The lifting magnet’s stainless steel robust lifting eye clamps product from the top without deforming or damaging the load.

The permanent MPI Lifting Magnet is widely used for handling ferromagnetic materials in the metal industry – in workshops, on building sites, in warehouses for semi-finished steel products, when handling steel workpieces, tools, sheets, metal profiled sections, tubes, and bars.


For free falling powder and bulk products.

Once installed in a gravity feed pipeline, bulk material falls through the metal detector. If any metallic contaminant, magnetic or non-magnetic is detected, the reject flap engages to promptly separate and exit the contaminant from the product stream.

METAL SHARK® Gravity Feed (GF) Metal Detectors, available in both standard and compact models, are used in gravity feed pipelines to monitor for unwanted metal contaminants in continuous flowing granules or powders.

The Metal Detector GF is commonly used for:

  • Powdered milk
  • Sugar
  • Cereal
  • Proteins
  • Spices
  • Granules
