Neodymium magnets are widely used in the Magnetic Filter Bar. This device is composed of neodymium magnets, a stainless steel tube made of either 304 or 316 stainless steel, a metal spacer placed between the magnets, and stainless steel ends. The neodymium magnets are positioned in a repelling manner and securely welded inside the stainless steel tube. This arrangement significantly enhances the magnetic force compared to using single magnets. Additionally, this assembly ensures optimal working conditions for the neodymium magnets, effectively safeguarding them against rust.

According to the grades of neodymium magnets used, the magnetic filter bar could be used in 80ºC (N grade); 100ºC(M grade); 120ºC (H grade);150ºC(SH grade); 180ºC(UH grade) ; 200ºC(EH grade).  SmCo magnets will be used if the working temperature is more than 200ºC.

The diameter of magnetic filter bar we could make varies from D10 mm to D50 mm. The most popular diameters are D20 mm,  D25mm.  The max. length of magnetic filter bar is up to 2500mm. Other shapes such as rectangular could also be made according to request of customer.  The peak surface gauss is decided by both the diameter of filter bar and grade of neodymium magnets, normaly from 4000Gs to 12000Gs

Magnetic separators offer several advantages in various industries and applications. Some key advantages of magnetic separators include:

1. Effective Removal of Ferrous Contaminants: Magnetic separators are highly efficient in removing ferrous contaminants, such as iron particles or metal fragments, from various materials. They can effectively separate and capture even very small ferrous particles, ensuring cleaner and purer end products.

2. Protection of Equipment: By removing ferrous contaminants from materials, magnetic separators help protect downstream equipment and machinery from damage. Ferrous particles can cause wear and tear on processing equipment, leading to increased maintenance costs and reduced equipment lifespan. Magnetic separators prevent such damage by removing these contaminants before they can cause harm.

3. Improved Product Quality: Magnetic separators contribute to improved product quality by eliminating ferrous contaminants that may negatively affect the performance or appearance of the final product. For example, in the food processing industry, magnetic separators can remove metal fragments from food products, ensuring consumer safety and product integrity.

4. Increased Operational Efficiency: Magnetic separators help improve operational efficiency by reducing downtime and maintenance requirements. By removing ferrous contaminants from materials, they prevent blockages, clogging, and damage to processing equipment, allowing for smoother and uninterrupted production processes.

5. Versatility and Adaptability: Magnetic separators are available in various configurations and designs, making them suitable for a wide range of applications and industries. They can be customized to meet specific requirements, such as different flow rates, material characteristics, and separation objectives.

6. Easy Installation and Maintenance: Magnetic separators are generally easy to install and require minimal maintenance. They are designed for long-term and trouble-free operation, with features like self-cleaning mechanisms that automatically remove captured ferrous contaminants, reducing the need for manual intervention.

7. Environmentally Friendly: Magnetic separators provide an environmentally friendly solution for separating ferrous contaminants. They do not require the use of chemicals or consumables, reducing waste generation and minimizing the environmental impact of the separation process.

8. Cost-Effective: Magnetic separators offer a cost-effective solution for removing ferrous contaminants. They help reduce equipment damage, maintenance costs, and product quality issues, resulting in improved overall operational efficiency and cost savings.

In summary, magnetic separators provide several advantages, including effective removal of ferrous contaminants, protection of equipment, improved product quality, increased operational efficiency, versatility, easy installation and maintenance, environmental friendliness, and cost-effectiveness. These advantages make magnetic separators a valuable tool in various industries, such as food processing, mining, recycling, pharmaceuticals, and many others.
