What are Grate Magnets?
Grate magnets, also known as magnetic grids or hopper magnets, are essential magnetic separators designed to remove ferrous metal contaminants from dry, free-flowing materials such as powders, granules, and liquids. These versatile devices are widely used across industries like food processing, chemical manufacturing, grain handling, and more to ensure product purity, protect processing equipment, and meet stringent quality standards.
How Does a Grate Magnet Work
A grate magnet typically consists of a series of magnetic tubes or bars arranged in a grid-like pattern (resembling a grate). This design creates a magnetic field that extends across the entire area where material passes through.
The function of a grate magnet relies on the principle that ferromagnetic materials are strongly attracted to magnetic fields. When product flows through or over the magnetic grate:
The magnetic field generated by the grate magnet pulls ferromagnetic contaminants toward the tubes/bars
These contaminants remain attached to the magnetic surface
The non-magnetic or less magnetic material continues to flow through
Customization Options
We understand that every application is unique. That’s why we offer full customization for our grate magnets, including:
- Shape and Size: Round, square, rectangular, or custom designs to fit your hoppers, chutes, or bins.
- Magnetic Strength: Choose from ceramic magnets for general applications or rare earth magnets for superior performance in critical environments.
- Material Options: 304 or 316 stainless steel for corrosion resistance, with food-grade finishes for sanitary applications.
- Special Features: Easy-clean designs, quick-release mechanisms, and integration with existing systems.
Quality and Compliance
Our grate magnets are manufactured to the highest standards, ensuring reliability and performance. For food-grade applications, our magnets meet the stringent requirements of HACCP standards (HACCP 0909MAGSEP 1-2010) and are constructed from 316 stainless steel with sanitary finishes to comply with FDA and USDA regulations. All our products undergo rigorous quality control processes to guarantee consistency, durability, and compliance with international standards.
