HOW DOES A MAGNETIC SEPARATOR WORK?



Based on the difference in magnetic characteristics of the ore minerals, magnetic separators are used to separate valuable minerals from non-magnetic gangue, such as magnetite from quartz, or magnetic impurities or other valuable minerals from non-magnetic values. Magnetic susceptibility is a characteristic of a magnetic separator that influences its response to a magnetic field. Materials can be classified into two groups based on their magnetic susceptibility: those that are attracted to a magnetic field are termed paramagnetic materials, and those that are repelled by a magnetic field are called diamagnetic materials.

Types of Magnetic Separator


Dry or wet magnetic separators are available. Permanent or Electro Magnet Magnetic Separator are two types of magnetic separators. Based on the relative magnetic field strength used to achieve separation, magnetic separators for the mineral processing sector are divided into three categories: low, medium, and high intensity. Magnetic separators include:

  • Wet high-intensity magnetic separators (WHIMS)
  • Wet / dry low-intensity magnetic drums (LIMS)
  • Induced roll magnetic separators (IRM)
  • Lift roll magnetic separators
  • Cross belt magnetic separators
  • Disc magnetic separators
  • Eddy Current Separator
Magnetic Separator Applications

Magnetic separators have been used to upgrade and beneficiate a wide range of minerals and commodities for a long time. There are three main applications for magnetic separators:
#1. Magnetic Separators for concentration or purification;

Magnetic Separators are used in ore processing to separate magnetic minerals, namely iron. For nearly 200 years, magnetic separation has been used in mineral processing.

#2. Magnetic separators for product cleaning;

Most common applications are listed as below:

  • Purification of Kaolin;
  • Removal of magnetic minerals from high quality quartz sand;
  • Separation ilmenite, monazite, zircon and garnet
  • Wolframite, cassiterite, tantalite, columbites concentration.

#3. Magnetic Separator for tramp iron removal;
Tramp iron separators safeguard handling and processing equipment such as screens, crushers, and pulverising machines, among other things. Magnetic pulleys on conveyor belts, plate magnets in chutes, grate magnets incorporated, and various magnetic drums fitted as independent components in separators are all examples of magnetic separators for tramp iron removal.

Top Magnetic Separators For C&D Waste Recycling And How They Work

Image
Introduction C&D waste volumes have been growing across the world. Creating valuable construction materials from this waste is crucial due to the scarcity of such materials. Construction and demolition (C&D) waste is generated from outlived construction demolition, repair, renovation, and construction works.  Recycling industry manufacturers can help divert Tonnes of construction, demolition, and excavation waste from landfill simply by transforming C&D waste into valuable construction materials.   Advanced separation and processing systems can help easily churn out washed, recycled sand and aggregates for valuable construction applications. For obtaining valuable construction materials from bulky and heavy demolition waste fractions, effective separation of non-ferrous metals is necessary.  Magnetic Separator for C&D waste is designed to handle heavy materials and separate non-ferrous metals. Read on to learn the top magnetic separators that can be u...

The Difference Between Overband Magnetic Separator And Inline Magnetic Separator

Image
Though the working principles of an overband magnetic separator and an inline magnetic separator are extremely similar, their purpose and performance are vastly different. This site was created specifically to distinguish between these items and to help you (the readers) understand what would be the best option for your needs. This topic's information, articles, and drawings will also be on display. What is the difference between an OBMS (Overband Magnetic Separator) and an OBMS (Overband Magnetic Separator)? An overband magnetic separator consists of a suspension magnet with a tramp belt connected to a motor that rotates the belt. It's mostly employed when ferrous contamination needs to be removed automatically. It's primarily used to remove tramp metal from products, vibratory feeders, inclined planes, or simply to protect machines like crushers and shredders. Industries that use this product include Foundries, Coal Mines, Cement Works, Food, Sponge Iron, Charcoal, Glass,...

How To Choose The Right Magnetic Separator For Your Applications or Process?

Image
  Introduction Installing the right magnetic separator is a necessary step for increasing operational efficiency and productivity. The selected magnetic separator should stand the test of time and meet various challenges of industrial applications, Picking the wrong magnetic separator will make it hard to separate impurities from the product and will lead to poor separation results and product damage. On the other hand, picking the magnetic separator correctly is critical to the success of the separation process. The right magnetic separator will lead to superior separation of impurities, improved productivity, low maintenance and repair costs, and quality end products. To better understand which is the right magnetic separator for your application, let’s go over some key considerations and details of various magnetic separators for different applications. Disadvantages Of Installing A Wrong Magnetic Separator If your processing line is equipped with the right magnetic separator, i...
