Magnetic Products Inc. (MPI) recently announced that it shipped what the company believes is the world’s longest beltless magnetic conveyor to the Lake City Army Ammunition Plant in Independence, MO, operated by Alliant Techsystems.

Traditionally, beltless magnetic conveyors range in length from 3 to 20 ft. ATK approached MPI with an unusual request. The plant’s new material handling line would require a conveyor that measured more than 90 ft -– the same length as five U.S.-made extended-cab pick-up trucks. While the dimensions of the proposed conveyor were daunting, the application also required that the equipment move unprecedented quantities of material per hour.

The conveyor is able to move ferrous metal objects by means of powerful permanent magnets located below a non-magnetic stainless steel slider bed. As the magnets move, objects travel along the conveyor and fall into a bin. Typical materials conveyed include metal, stampings, turnings, chips, fasteners, and scrap. With no external moving components except for the drive motor assembly, the liquid-tight sealed conveyor housing can be completely submerged in machine reservoir tanks while the internal self-adjusting take-up system eliminates the need for maintenance.
