Grate Magnets
MSI’s tubular magnetic circuit is the cornerstone for the majority of our customer’s fine separation and free-flowing dry solid applications. This circuit utilizes magnetic elements which provide powerful, evenly distributed magnetic fields within stainless steel tubing. More than one tube can be combined for additional protection to cover small or large areas alike. The tube circuit is the basis for such popular MSI products as grate magnets, drawer in housings, and even pneumatic and hydraulic applications such as our bullet magnets and T-Traps.
The tubular magnetic circuit can employ various thicknesses of tubing in order to improve durability or performance. As with most of our products, customers can choose between ceramic and rare earth magnetic elements for a wide variety of strengths and operating temperatures. Standard construction is 1” diameter stainless tubes with heavy-duty stainless framing, though other configurations are available.

Tube & Grate Magnets
The most basic conception of the tubular magnetic circuit is the tube magnet itself. These are available in a wide variety of sizes, but typically are 1” in diameter and 4” to 48” long with magnetic poles approximately every inch along the length. Multiple tubes can be combined to make grate magnets (see image).
Drawer-in-Housing Magnets
MSI’s drawer-in-housing is designed for removal of ferrous in various dry processing applications. It utilizes the tubular magnet design placed in a drawer with either a single row or, more commonly, multiple offset rows with alternating centers. The product flows through the top and over the offset magnetic tubes, causing it to slow down and contact multiple tubes as it cascades through the separator. This increases the amount of ferrous exposed to the magnetic poles, thus maximizing separation. The drawer-in-housing is available in almost any configuration the customer can imagine, but primarily these units fall into one of three different cleaning categories: manual clean, EZ-Clean, and self-cleaning. The cleaning style used is typically based on volume of tramp metal since magnets must be kept clean to be effective.

Cleaning Options
MANUAL CLEAN
Still part of the “drawer” style, the manual clean drawer in housing is effectively a grate or multiple grates in a housing. This is the most basic configuration, popular in applications that either do not need frequent cleaning (such as a finishing step after a primary magnetic separator) or when a very specific finish on the working surfaces is required (such as pharmaceutical applications). The manual clean drawer in housing must be cleaned by hand and cannot protect against ferrous during the cleaning process.
EZ-CLEAN
The EZ-Clean drawer-in-housing employs a stripper plate and wipers that wipe off the magnetic tubes. As the drawer assembly is pulled out, the tubes pass through the wipers and ferrous is retained against the stripper plate. Once out of the magnetic field, the ferrous falls off (typically into a container) and the drawer can be returned to the working position. This cleaning cycle can be done in a matter of seconds, greatly reducing down time in time-sensitive applications. By employing multiple stripper/wiper assemblies, protection does not necessarily need to be interrupted during the cleaning cycle.
SELF-CLEANING
The Self-Cleaning drawer in Housing is the same as the EZ-Clean, but uses pneumatic cylinders to actuate the cleaning cycle. These are especially popular with systems hooked up to an automated control system or when operator access is difficult.
