Magnetic Separation is one of the most common and important physical separation techniques and there are many varieties of magnetic separation equipment available. The basic concept of a Magnetic Separation is that magnetically susceptible particles or bodies are separated from non-magnetic particles. However, the simplicity stops there. To enable different levels of separation from a wide range materials, there is a extensive range of different Magnetic Separator designs.
Depending on the magnetic susceptibility, minerals can be paramagnetic, ferromagnetic, or diamagnetic.
Magnetic Separator Applications: Recycling, Mineral Processing and Ceramics, Mining and Quarrying, Food Production,ect.

CJ Magnet can provide you with Neodymium, Ferrite, Samarium Cobalt, Alnico rare earth permanent magnets and magnet assemblies.We can also provide you with customized services.

Rod magnets are available as raw magnets or as a magnet system. However, since raw bar magnets are quite brittle, bar magnet systems (a raw magnet surrounded by a steel cup) are mainly used in areas such as mechanical engineering, tool construction or assembly technology.
Product features to your advantage:

• Available are bar magnet systems made of neodymium, samarium-cobalt and AlNiCo.
• Easy installation due to cylindrical shape.
• Installation by gluing, shrinking or careful pressing.
• Magnetic system protected by brass pot.
• Rod magnet systems are shielded, i.e. they practically do not disturb the environment,

Neodymium disc magnets, also known as round magnets, are among the most popular types of magnets. They are extremely versatile in their use and achieve remarkable adhesive forces even at a small size. Responsible for that is the neodymium-iron-boron combination, which is currently the strongest available magnet material in the world. The advantages of neodymium disc magnets at a glance:

Neodymium Magnets Features & Characteristics
Grades & Materials - Neodymium magnet materials in both standard and premium grades for reduced production and lead times. We offer sintered neodymium magnets in grades ranging from N30 to N55.
Sizes & Shapes - Sizes for standard Neodymium Iron Boron rare-earth magnets range from a few millimeters to approximately 150 mm, while assemblies can weigh up to several tons. Standard shapes include discs, blocks, rings, and arc segments in various sizes and grades. Non-standard shapes and sizes can be custom fabricated exact specifications from raw stock.
Temperature Considerations - Neodymium magnets are temperature sensitive. For applications in which the magnet may be exposed to temperatures in excess of about 250°F (120°C), careful consideration must be given to the choice of magnet grade and the magnetic circuit.
Manufacturing Methods - Due to the relatively brittle nature and high-magnetic strength of NdFeB magnets, cutting and grinding should be done prior to magnetization. We are fully equipped to machine these materials to virtually any shape and size for your project’s specialty requirements using our in-house grinding and EDM facilities. Finishing to tolerances of +/-0.05mm can be achieved, as required.
Surface Treatments - Neo magnets are susceptible to oxidation, so painting, epoxy coating, or plating is highly recommended to prevent corrosion. The common surface treatments include nickel plating, zinc, or epoxy coatings.
Handling & Storage - Neodymium materials are relatively brittle, but are magnetically very strong. They must therefore be handled carefully to avoid injury to personnel and damage to the magnets.

Industrial & Consumer Applications for Neodymium Block Magnets
Neodymium block, bar, and cube magnets are useful for multiple applications that require high magnetic strength. Many industries rely on neodymium magnets' advanced characteristics from design & engineering to creative DIY projects. Specific applications that utilize neodymium block, bar, and cube magnets include:

Filter systems easily separate iron particles and chips being produced by abrasion or soiling from the material
