In the early s, American engineer Richard James was experimenting with springs when he noticed that some of his equipment was attracted to each other. This led him to develop the first magnetic separator, which could remove ferrous contaminants from dry, free-flowing materials. During World War II, James’ magnetic separators were used in the food industry to remove metal contaminants from sugar and flour. After the war, they were also used in the mining and coal industry to remove metal impurities from ore and coal.
Today, magnetic separators are used in a variety of industries, including food processing, pharmaceuticals, textiles, recycling, and mining. They are also used to remove metals from fluids and gases.
Using magnetic separation equipment resolves a variety of industry problems
The use of magnetic separators in the food, dairy, and grain industries has long been an accepted part of sanitary design.
-The first step in the design of a magnetic separator is to determine the type of material to be processed.
-The next step is to choose the strength of the magnet that will be used.
-The third step is to determine the size and shape of the device.
-Finally, the fourth step is to select the type of sensor that will be used to detect ferrous contaminants.
Magnetic separators are devices that are used to remove ferrous contaminants from dry, bulk products such as cereal grains, flour, sugar, coffee beans, tea leaves, spices, and minerals. These devices are also used in industries such as glass manufacturing and plastic recycling. In addition, magnetic separators are often used in conjunction with other types of equipment such as belt conveyors and vibratory feeders.
Magnetic separation equipment comes in a variety of sizes and strengths. The selection of an appropriate device depends on several factors including:
-The type of product being processed
-The size of the product particles
-The presence or absence of ferrous contaminants
-The desired purity level
When it comes to choosing the right metal separator for your needs, you’ll want to consider a few factors. The first is the SIZE of the particles you’re trying to remove. The second is the TYPE of ferrous material you’re dealing with. And the third is the LEVEL of ferrous contamination you’re trying to achieve.
There are a number of different designs of magnetic separators, and each has its own advantages and disadvantages. Here are some of the most popular designs:
These are used for removing smaller pieces of ferrous contamination from product streams. Overhead magnet separators typically have a conveyor belt that carries contaminated products underneath a powerful magnet. The magnet attracts and captures any Ferris contaminants in the product stream before they can reach the end of the conveyor belt.
This series contains magnetic pulleys with different numbers of magnetic rollers, which have one, two, or more magnetic rollers. And the rollers also have different magnetic field strengths ranging from Gs to Gs.
Permanent magnetic pulleys rotate at slow speeds. As the drums rotate, they create a magnetic field that captures ferrous contaminants and pulls them away from the product stream, which means scrap iron. Placing these magnets after process machinery that is susceptible to breakdowns, or prior to process machinery that may become severely damaged as a result of tramp metal, will help keep the processed product free from impurities. Magnetic drum pulleys are often used in recycling plants and auto-shredding facilities.
These are similar to cross belt separators, but they use only one drum instead of two or more. Drum separators are mostly used for removing larger pieces of ferrous contamination, such as nails, bolts, and other metal fragments.
Industrial metal separators come in many different varieties and are used for a range of purposes. These separators can be used to remove ferrous contaminants from dry, free-flowing materials such as granulates, powders, and pellets. Ferrous contaminants can cause product quality issues, damage processing equipment, and pose a safety hazard. Separating metals can also help to protect downstream processes and equipment.
There are many different types and designs of plate magnets available on the market, so it is important to choose the right one for your specific application. Plate magnets can be used for a variety of applications, such as removing tramp metal from product flow streams, protecting processing equipment from damage, and increasing product purity.
When choosing a plate magnet, you must first consider the type of metal that needs to be removed. For example, if you are looking to remove ferrous metals, you will need a ferrite or rare earth magnet. If you are looking to remove non-ferrous metals, such as aluminum or brass, you will need a ceramic or rare earth magnet.
Once you have chosen the right type of magnet for your application, you must then consider the size and strength of the magnet. The size of the magnet should be appropriate for the size of the product flow stream. The strength of the magnet should be strong enough to remove all of the desired metals from the product stream.
It is also important to consider how easy the plate magnet is to clean. If the magnet is going to be used in a wet environment, it is important to choose a design that allows for easy cleaning. Some plate magnets have removable plates that can be taken off and cleaned separately from the rest of the unit. Others have hinged doors that allow access to the interior of the unit for cleaning purposes.
Finally, you must consider your budget when choosing an overhead magnet separator. There

When it comes to magnetic pulley designs, there are a few things to keep in mind. First, you want to make sure that the design is able to keep the magnetism focused in one area. This will ensure that the separation process is as efficient as possible. Second, you want to make sure that the design can withstand the wear and tear of constant use. The last thing you want is for your magnetic pulley to break down after only a few uses. Finally, you want to make sure that the design is easy to clean and maintain. The last thing you want is for your separator to become clogged with debris over time. There
Industrial metal separators come in a variety of shapes and sizes, but all use powerful magnets to capture unwanted metal contaminants from materials passing through them. One common type of metal separator is the magnetic drum, which is used in many industries such as food processing and mining.
Magnetic drums can be either permanent or electromagnets, and each has its own advantages and disadvantages. Permanent magnetic drums are typically lower in cost and require no power source, but their magnetic strength can diminish over time. Electromagnetic drums are more expensive but their magnetism is stronger and more consistent.
When choosing a magnetic drum for your business, you’ll need to consider the size and type of materials you’ll be processing. You’ll also need to decide whether you need a high-strength or low-strength magnet. High-strength magnets are better for capturing smaller metal contaminants, while low-strength magnets are better for larger metal contaminants. There

In , Eriez Magnetics patented both permanent magnetic and electromagnetic eddy current separators. Today, these powerful systems feature improved permanent magnetic circuits with rare earth magnetic material for stronger eddy currents and improved separation of non–ferrous materials.
In operation, the non–ferrous separator utilizes permanent rare earth magnets to induce eddy currents into metallic particles. This produces repelling forces which separate the metallics from non–metallics, providing a cleaner product for further processing. Removal of the metallics is selective and product loss is minimized.
The non–ferrous metallic separator consists of an external drum, an internal permanent magnetic rotor, a drive, and belt conveyor. The external drum shell of non–metallic composite material rotates at conventional belt conveyor speed. The internal Rare Earth alternating polarity rotor turns at much higher RPM than the external shell.
Through the induction of eddy currents and the resulting repelling forces, the alternating magnetic field selectively repels the non–ferrous metals and physically separates them from other materials with minimum product loss.
Eriez' Ultra High-Frequency Eddy Current Separator recovers ultra-fine aluminum, copper and other nonferrous fines materials typically missed on traditional eddy current separators from ASR. The UHF Eddy’s combination of a rotor designed to produce exceptionally high gauss at the belt’s surface, with a large number of magnetic poles operating at higher rpms creates ultra high-frequency changes resulting superior separation of fine nonferrous and even bare copper wire. This UHF Eddy provides an economical solution to improve Zorba recovery without the need for additional expensive sensor based or optical sorting equipment.
Each 1.0M (40" wide) unit ships with an Eriez Brute Force feeder to provide even distribution of material across the width of the conveyor.
