Reciprocating Drawer Magnet
“Type A” magnet circuits, typically used in drawer-style magnets, are the best choice to effectively capture metallic fines and weakly magnetic metals such as stainless
steel. For this reason, drawer magnets are the preferred solution for applications involving free-flowing products (whole grains, pellets, etc.) transported in gravity-fed
material handling systems, such as vertical chutes.
Often, this favored solution is not suitable due to product flow characteristics. Difficult-flowing products can bridge as they pass through magnetic tubes located inside
a traditional drawer magnet. This issue generally is resolved by increasing the distance between magnetic tubes which form the core of the drawer magnet’s
performance potential. An increase in distance, however, means an increase in the amount of product that travels outside the reach of the magnetic field. As a result,
tramp metals could slip by and contaminate final product or damage processing equipment. While some manufacturers can accept this risk, others cannot.
Eager to eliminate the trade-off between effective magnet coverage and potential product bridging, MPI developed the patented reciprocating drawer magnet (RDM).
MPI’s RDM boasts reciprocating tube magnets which act as knives to break up product as it flows through the tubes, allowing it to travel freely through the drawer
magnet. Continuous horizontal movement of the magnetic tubes prevents product bridging and choking. The reciprocating action of the RDM series drawer magnet
also significantly improves the unit’s ability to capture unwanted metals, resulting in greater performance.
