Square Magnetic Rod

Structure & Materials

Square Magnetic Rods feature a layered structure with an outer square stainless steel tube made of SUS304 or SUS316L, and an internal high-performance permanent magnetic core composed of rare earth Neodymium (NdFeB) magnets combined with low-carbon steel magnetic conduction plates.

The smooth, burr-free surface makes square magnetic rods especially suitable for coating machines and installations with limited or specific space requirements.
The corrosion-resistant and wear-resistant stainless steel housing effectively protects the internal magnetic core, ensures easy cleaning, and supports hygienic applications.
Various end connections are available upon request, including internal thread, external thread, lifting eye, or other customized designs.

Features & Specifications

Unlike traditional round magnetic rods, where magnetic flux lines are distributed around a cylindrical surface, square magnetic rods concentrate magnetic force on four flat surfaces.
This design allows users to flexibly utilize the effective magnetic faces based on installation conditions.

The square structure fits more closely to equipment inner walls such as chutes, pipelines, and processing chambers, enabling dead-zone-free iron removal. Square magnetic rods can be embedded into various production lines for continuous separation.

Technical Parameters

Key Advantages

1. High Iron Removal Efficiency

Equipped with NdFeB permanent magnetic cores, surface magnetic strength reaches 6000–14,000 Gauss, enabling rapid capture of fine ferrous contaminants and preventing equipment wear and product contamination.

2. Strong Application Flexibility

Square magnetic rods can be customized in cross-sectional dimensions, length, and magnetic strength. They are suitable for installation in coating machines, pipelines, hoppers, and other processing equipment, handling powder, granular, and liquid materials.

3. Low Operating Cost

Permanent magnetic design requires no power consumption and minimal maintenance. The corrosion-resistant, smooth surface allows easy cleaning by simple wiping, ensuring long service life and low total operating cost.

4. Safe & Environmentally Friendly

Physical magnetic separation does not change the chemical properties of materials, requires no consumables, and generates no secondary pollution. Fully compliant with food-grade and medical-grade hygiene standards.

Applications

Square Magnetic Rods are widely used in food processing, chemical and pharmaceutical manufacturing, lithium battery and electronic materials, plastics and rubber processing, ceramics, and glass industries, providing reliable iron removal across a wide range of production environments.
