Magnetic Grids
Your Professional Magnetic Grids Supplier！
Established in 2003, Hesheng Magnetics is one of the earliest enterprises engaged in the production of neodymium rare earth permanent magnets in China. We have a complete industrial chain from raw materials to finished products.we have become the leader in the application and intelligent manufacturing of neodymium permanent magnets field ,after 20 years development,and we have formed our unique and advantageous products in terms of super sizes, magnetic Assemblies,special shapes, and magnetic tools.
Magnetic grids (or magnetic grates) are high-intensity, industrial magnetic separators used to remove ferrous contaminants—like iron, rust, and steel filings—from free-flowing powders, granules, and liquids. Placed in hoppers or pipelines, they protect machinery and ensure product purity in industries such as food, plastics, and pharmaceuticals.

Product advantages
Equipment Protection
By capturing ferrous particles before they reach sensitive equipment like mixers, grinders, or packaging machines, magnetic grids prevent wear, damage, and costly downtime.
Ease of Use
Unlike active filtration systems, magnetic grids operate passively with no need for electricity or motors. Maintenance is minimal, cleaning is simple, and operating costs are virtually zero.
Adaptability
Magnetic grids can be custom-built to fit almost any chute, bin, or pipe. Whether you’re handling fine powders, plastic pellets, or large granules, a grid can be tailored to suit your product and process.
Cost-Effective
Though simple in design, magnetic grids are incredibly efficient. Their long lifespan, minimal maintenance, and ability to reduce product loss or equipment repair make them a high-ROI investment.
Shape Variations
The shape of thegrate magnetdepends entirely on your equipment interface.
Circular Grids:
These are the industry standard for conicalhopper magnets. They drop directly into the throat of the hopper to protect injection molding machines or extruders.
Rectangular/Square Grids:
We use these for square chutes, bins, and ductwork. The goal is to cover the entire cross-section of the material flow so there are no “dead zones” wheretramp metalcan slip through.
Application
Food Processing: Checking for any metallic issues on consumables is very important to meet the health requirements of the customer.
Pharmaceuticals: It is crucial to retain the purity of medicinal products, and grid magnets can assist in avoiding contaminants during production.
Plastics Manufacturing: Crucial to the investment of colors for plastic items is to eliminate any kind of contamination by metal as this negatively affects quality and may cause damage to machines during the molding process.
Recycling and Waste Management: Sorting ferrous metals from other materials improves the efficiency of the recycling process and also reduces the tendency to wear out common tools, and equipment used.
Structure
Magnetic Bars/Tubes:
The core component consists of permanent magnets, usually Neodymium Iron Boron, inside 316-grade stainless steel tubes.
Stainless Steel Frame:
Holds the magnetic bars together in a sturdy, durable framework, often welded for structural integrity.
Magnetic Circuit:
Engineered to create a uniform, high-intensity magnetic field (up to 12,000+ Gauss) on the surface of the tubes to capture tiny ferrous contaminants.
Deflectors (Optional):
V-shaped deflectors are sometimes placed above the tubes to force materials to pass directly over the magnetic tubes, increasing the probability of contaminant capture.
Custom
Sizes & Shapes
We offer neodymium magnets in sizes from 0.010" to large assemblies, with standard shapes like discs, blocks, rings, and arc segments. Custom shapes can be made to your specs.
Grades & Coatings
Available in grades N35 to N52. To prevent corrosion, magnets are coated with options like Nickel (Ni-Cu-Ni), Gold, Chrome, Copper, Epoxy, Teflon, and Rubber/Plastic.
