Magnetic conveyors use electromagnetic force to transport ferrous metal objects in industrial processes. There are two types: moving belt and static bed sliding conveyors. They prevent spillage and are ideal for steep slopes. Two types of magnetic conveyors are the moving belt and static bed sliding conveyors.
A magnetic conveyor is a material transport mechanism used to move ferrous metal objects using a combination of conventional conveying technology and electromagnetic force. These conveyors are typically used to transport unit parts, scrap or metal fragments from one point in an industrial or manufacturing process to another. There are two basic types of magnetic conveyor systems namely the moving belt and the static bed sliding conveyors. Both, however, use electromagnets to hold the metal load to the surface of the conveyor during transportation. This adhesion to the conveying surface makes the magnetic conveyor an ideal solution for applications that require steep slopes in the path of the conveyor.
Most conventional transportation systems have a basic weakness: spillage, particularly around curves and steep slopes. The magnetic conveyor solves this problem by holding the load firmly in place on the transport bed by means of electromagnets placed under its surface. Obviously this means that the systems are only effective when used to transport ferrous metals which are attracted to the magnetic field. These materials are usually loose manufacturing parts, molding offcuts, or scrap metal. Chips, or trimmings, from large-scale metalworking processes are also commonly removed using a magnetic conveyor system.
There are two basic types of general purpose magnetic conveyors. The first is of the moving belt type, which is a conventional conveyor with a continuous array of powerful electromagnets located underneath the carrying portion of the belt. When metal objects are placed on the conveyor, they are attracted to the magnetic field and adhere firmly to the belt surface. The string of magnets will terminate just before the conveyor discharge point, meaning that items will then be free to fall off the belt into the discharge chute or hopper.
The second type of magnetic conveyor is the static bed sliding variant. These devices have a smooth, static carrying surface, with the magnet array moving underneath it. When objects are loaded onto the bed, they are attracted by the magnetic field and dragged along the smooth transport surface. The magnet array is situated in a continuous loop and will reach the end of its stroke at the discharge point, allowing the material to leave the transport bed. Due to the fact that spillage with these systems is minimal, the Magnetic Conveyor is the ideal choice for processes that require conveying routes with sharp curves and steep or even vertical slopes.
