Rectangle Magnetic Grate

Rectangle Magnetic Grate is a permanent magnetic separator designed to remove ferrous contaminants from dry bulk materials such as powders, granules, and grains. It is typically constructed with high-strength magnetic bars arranged in a rectangular stainless-steel frame, allowing materials to flow through the grid while iron particles are captured by the strong magnetic field. Installed in hoppers, chutes, or pipelines, it helps improve product purity and protects downstream equipment in industries such as food processing, plastics, chemicals, and pharmaceuticals.

FAQ

What materials can a magnetic grate remove?
Magnetic grates are designed to capture ferrous contaminants such as iron filings, metal fragments, bolts, and tramp iron from powders, granules, and bulk materials during processing.

Where are magnetic grates typically installed?
They are commonly installed in hoppers, chutes, pipelines, feeders, and material transfer points where bulk materials flow through the magnetic grid.

What magnetic strength should I choose?
The required magnetic strength depends on the material type and particle size. For fine powder or high-purity applications, high-intensity rare-earth magnets up to 12000–15000 Gauss are typically recommended.

Can the magnetic grate be customized for my equipment?
Yes. Manufacturers usually provide custom sizes, magnetic bar spacing, frame structures, and connection types to fit existing production systems.
