How Is a Magnetic Separator Used?

A magnetic separator consists of a powerful magnet that is placed or suspended from a ceiling or device. Materials can be passed over a table top magnetic separator, while suspended magnetic separators often hang over a material to remove its impurities. Magnetic separators can also be cylinders through which objects pass. The material that purifies a magnetic separator can be in the form of parts, a finished product or even a liquid metal. With this, a magnetic separator is characterized by:

To be an excellent machine to separate magnetic materials from concentrates.

Removes natural magnetic minerals such as magnetite, as well as steel filings from metal processing material and iron particles.

Remove magnetic like gold concentrates, because it allows gold to recover much more easily.

Why Is Magnetic Separation Important?

Magnetic separation has changed the world, and is responsible for product and food safety standards that we sometimes take for granted. Thanks to the innovations of magnet applications, we are able to eat food and use products that are free of dangerous materials. Magnetic separation also protects your equipment from serious damage by keeping the line clear of hazardous metal scraps. Whether you're in the Food, Dairy, Grain and Milling, Chemical, Plastics, Oil, Textile, Recycling, Powder and Bulk, Mining, or the Non-Woven industries, magnetic separation applications are crucial to the success of your business.

Through the use of magnets, you are able to separate hazardous metals from your product before it's shipped to consumers. This is extremely important for a number of reasons. When tramp metals are found in product and food, it can result in potential lawsuits, product recall, negative press, and severe injury to customers. Fortunately, this can all be avoided by investing in the right magnetic separation applications. The magnet separator you choose will depend on the type of material being processed and the system you are running the material through. Each system and product is unique, which means there is no "one size fits all" solution when it comes to magnetic separation.

Magnets Used in Magnetic Separators

For the permanent magnet separator, the permanent magnet is its most important component, and the quality of the permanent magnet determines its performance. Permanent magnets of magnetic separators are generally made into a certain size, so they are customarily called permanent magnet blocks or magnet blocks for short. The permanent magnet materials that can be used as the magnetic system of the magnetic separator include ferrite, AlNiCo, iron-chromium cobalt, manganese aluminum iron, samarium cobalt permanent magnet materials, and neodymium iron boron permanent magnet materials. At present, the mainstream permanent magnet materials used in magnetic separation equipment are mainly ferrite, followed by neodymium iron boron permanent magnet materials. In the design of the magnetic circuit, it is necessary to choose which permanent magnet material to use according to the specific conditions of various aspects. The influencing factors can be summarized in the following aspects:

Magnetic field strength. A constant magnetic field is to be generated in the designated working space. The strength of this magnetic field determines which permanent magnetic material needs to be used. The magnetic properties of neodymium iron boron permanent magnets are much higher than ferrites.

The requirements for the stability of the magnetic field, that is, the adaptability of the permanent magnet material to environmental factors such as temperature, humidity, vibration,and shock.

Mechanical properties, such as the toughness, flexibility, and compressive strength of the magnet.

FAQ

Q: 1.How does a magnetic separator work?

A: Magnetic separators use basic magnetic principles to remove ferrous material from substances such as granules, grains, pellets, powders, and paste. They are commonly installed within the product stream at key points.

Q: 2.What is the function of magnetic roller?

A: Also known as magnetic drum. They are used for automatic cleaning of loose materials, ex. granulate or pellets, moving along the conveyor belt from ferromagnetic impurities.

Q: 3.How do magnetic rollers work?

A: Magnetic rollers get their name from how well they hold hair. They aren't actually magnetic. In fact, most are made of straightforward plastic cylinders with ventilation holes cut through them. They're meant to be used with wet hair that clings to the rollers like they're - you guessed it - magnetic.

Q: 4.What are the two types of magnetic separators?
