A magnetic bar is a cylindrical device composed of strong rare-earth neodymium /SmCo magnets enclosed within a waterproof stainless-steel housing. These bars are specifically designed to remove ferrous contaminants from materials in a wide range of applications, including powders, liquids, and bulk materials.
The bars consist of multiple magnets that create a magnetic circuit, doubling the strength of the magnetic field compared to a single magnet. This enhanced field allows the magnetic bar to effectively absorb and remove fine metal particles, down to 30 µm in size. The polished stainless-steel housing is durable and food-grade compliant, making magnetic bars suitable for industries that require stringent hygiene standards, like food and pharmaceuticals.
Magnetic bars can be placed directly into tanks or chutes or arranged in grids to form complete filtration systems. These versatile tools require no additional energy, as they rely on permanent magnets for their operation, ensuring efficient and cost-effective protection of both products and equipment.
Magnetic filtration allows fluids to flow around a magnetic core or rod, with the high-power neodymium magnets attracting any ferrous particles and removing them from the machine’s fluids, clean fluids are then returned to the machine which prevents costly repairs and extends the life of the equipment.
Magnetic filter bars, also known as magnetic rods or tube magnet, are designed to efficiently remove fine iron contaminants from free-flowing materials like powders, granules, and liquids. These bars are available in various sizes and configurations, making them versatile for different filtration systems or standalone use.
Neodymium filter rods are constructed with a full seal welded structure to ensure strength and contamination prevention.
These rods use powerful neodymium magnets and steel pole pieces, encased in stainless steel covers such as 304, 316, or 316L, chosen based on industry requirements.
This design creates a strong magnetic field, making the rods ideal for effectively filtering ferrous materials in magnetic filter and grate systems, optimizing performance and durability for a range of industrial applications.
These are general guidelines. To ensure the best solution for your needs, we encourage you to share your specific application and desired results, and we’ll tailor a recommendation that meets your requirements.
Magnetic bars are essential for filtering out fine iron particles and weakly magnetic contaminants, typically ranging from 30 µm to about 2 mm, in various industries. These bars are used in systems that handle fine powders, liquids, and viscous materials in bulk flows or pipeline transport. The ideal surface gauss depends on the specific application:
To check the strength of a tube magnet, a Gauss meter is typically used. This device measures the magnetic flux density on the surface, specifically from the top of the stainless steel casing. The surface gauss reading helps assess the magnet’s performance and ensures it meets your application requirements. Regular measurement and record-keeping are important for maintaining consistent magnetic strength and ensuring reliable filtration over time.
When choosing a magnetic filter bar, it’s important to consider several key factors to ensure it meets your application needs. By focusing on these elements, you can select a filter bar that provides efficient filtration and long-lasting durability for your system.
Magnetic filter bars and rods come in a variety of shapes to accommodate different industrial needs. Common shapes include round, square, and rectangular, each designed to fit specific system configurations and optimize filtration performance in diverse applications.
When selecting stainless steel for magnetic filter bars, SS304 and SS316/316L are the most popular choices. SS304 is widely used due to its versatility and suitability for most environments. However, for applications requiring higher resistance to corrosion, such as in the pharmaceutical or food industries, SS316 or SS316L is often a better option because of its superior protection against chemicals and moisture.
