A grid of magnetic rods or bars is positioned in a cross-sectioned area of a pipe, discharge chute, or hopper. Grate Magnets are designed for small, dry, granular free-flowing powder. Once you’ve considered all your unique application requirements, it’s time to match them with a magnetic separator that meets your needs. flour or cornstarch)Ĭhoosing the Right Design for Your Application Dry powders with bridging characteristics.Some of the categories that deserve consideration are: Perhaps one of the most important considerations is the type and consistency of your powder. If the magnetic separator is manually cleaned, how will the magnetic separator element be handled? Are there any ferrous materials nearby that could pose a safety hazard?.Can the system be stopped to clean the magnet or will you need a self-cleaning magnet?.

Is the material coming to the separator evenly or in surges?.

You’ll need to determine the level of product purity required. The type of separator needed will depend on several process considerations. If a material clumps, for example, it may plug the separator’s opening, requiring the position of the magnetic rods to be adjusted to create more space for the product to flow freely. How the material flows makes a difference, too. The material moving past the magnet needs to be metered so that the magnetic field can capture any contaminants. So, it’s important to design a filter within the magnet’s maximum temperature, or contaminants in your particle stream will pass right through the magnetic separator. Heating a magnet past its maximum operating temperature, but below its curie temperature, will cause the magnet to lose its strength over time. Once a permanent magnet gets heated past its curie temperature, the magnets structure is altered and the magnet will lose it all of its strength as well as its ability to be re-magnetized. Gauss is the measurement by which a magnet’s strength is measured. The curie temperature is the temperature at which a magnet completely loses all of its gauss.

They start to lose strength at their maximum operating temperatures.Īll magnets also have what is called a curie temperature. High temperatures can alter a magnet’s effectiveness. Temperature, flow rate, flow characteristics, and process issues should all be considered during the decision-making process. Selecting the right magnetic separator for your application will depend on several factors. And while they are the most powerful permanent magnet, they have their shortcomings that all of their power cannot overcome.ĭid you know that a magnetic field can be too strong? “Neo” magnets, which is slang for Neodymium Iron Boron magnets, are in a family of magnets that are referred to as “permanent magnets.” All of the magnets in the permanent magnet family, all provide something that their siblings cannot. Many would have you believe that “Neo” magnets are the end-all-be-all when it comes to separating ferrous material from non-ferrous material. The field of magnetics (no pun intended) is vast. Magnetic Separators: Knowing the Ideal Magnet Material & Circuit for Your Application To better understand which type of magnetic separator is right for your facility, we’ll explore magnet materials, examine process applications, then delve into magnetic separation equipment designed to meet the requirements of a multitude of applications. However, if your conveying system is equipped with the proper magnetic separator, you’ll be able to capture metal contaminants to deliver a final product that meets your industry’s sanitary standards. Most importantly, it can lead to contamination, which would cause a loss of product, revenue, and profit - or worse if that contaminated product makes its way to your customer or the consumer. No machinery is immune to wear from blowers, pumps, feeder, belt conveyors or rotary valves.īut when metal debris isn’t captured it can cause costly downtime and machine repair, even going so far as to require the need to purchase new machinery. Powder processing facilities have plenty of machinery with aggressively moving parts that have been known to shake loose fasteners or wear down surfaces to produce tiny metal particles or big metal pieces. Inline Magnets for Bulk Solids Conveying.
