What Are Grate Magnets?

First things first – what are grate magnets?

Grate magnets consist of magnetic rods or bars arranged in a grid or grate formation. They are placed inside processing equipment like hoppers, chutes, and pipelines.

As materials flow over the grate, the magnets attract and capture any iron contaminants. This removes metal debris before it reaches downstream processes.

Grate separators come in many shapes, sizes, and strengths. Magnetic circuit designs include permanent magnets made from materials like ferrite, neodymium iron boron (NIB) or samarium cobalt (rare earth).

These allow grate magnets to lift a range of particle sizes from powders up to bulk fragments.

Why Use a Grate Magnet for Separation?

Now you know what grate magnets are. But why are they so popular?

Well, grate magnets give extremely efficient separation compared to other techniques. They also protect equipment from damage.

Here’s why grate magnets should be your first-choice metal separator:

Maintain Product Quality

Contaminant particles as small as 0.1mm can be captured by a grate magnet. This excellent filtration preserves the purity of bulk solids and powders during processing.

For manufacturers, clean finishes are essential – particularly in sectors like:

  • Food production
  • Pharmaceuticals
  • Plastics
  • Chemicals

By extracting debris, grate magnets prevent discoloration, smell or texture changes from metallic contamination.

Reduce Equipment Wear

Stray iron particles cause rapid wear inside conveying systems, grinders, crushers and mixers. This abrasion leads to tears, jamming, blockages and failures.

Grate magnets stop loose metal from reaching equipment. So they slash damage from debris, as well as unplanned downtime and maintenance costs.

Improve Workplace Safety

Iron fragments in powders pose an invisible threat to factory staff and equipment. Metal detection methods only pick up larger pieces – missing microscopic particles.

But magnetic separators lift even microscopic debris to deliver clean, safe material flows. Protecting workers from the risk of combustion, surface damage or breathing issues.

Provide Ongoing Savings

While grate magnets require an initial purchase cost, they deliver exceptional long-term value through:

  • Lower equipment repairs
  • Less product waste
  • Reduced testing costs
  • Higher manufacturing uptime
  • Improved workplace safety

Factoring in these savings, grate magnets give an excellent return on investment over years of service.

5 Big Benefits of Using a Grate Magnet

Now that you know why grate magnets are useful – what are the specific advantages?

Here are 5 major benefits of installing a magnetic grate:

1. Adaptability

A key benefit of grate magnets is flexibility. With customized dimensions and magnet types available, they can handle almost any application.

Grate separators mount onto existing equipment like hoppers, chutes, pipes and conveyors without modification. Or permanent housings allow convenient retrofits.

This adaptability makes grate magnets easy to incorporate into your metal separation process.

2. Effective Contaminant Capture

Advanced magnetic circuit designs allow grate magnets to lift even weakly magnetic particles smaller than 0.1mm.

This efficient capture protects product quality and equipment in cases where other separators would miss debris.

Rare earth magnetic rods provide exceptionally strong fields able to filter huge volumes of material. So grate magnets reliably extract contaminants without slowing your processes.

3. Low Operating Costs

Because grate magnets are a passive separation tool requiring no external power, operating costs are extremely low.

Self-cleaning variants with shaking or rotary functions also minimize manual cleaning labor too. This efficiency keeps expenses down.

While grate magnets need occasional expert recharging after many years of use, savings from higher uptime offset this small cost.

4. Quick, Simple Maintenance

Basic grate magnets can be cleaned manually by removing adhered particles. But self-cleaning models make maintenance even easier.

Shaking, sliding and rotary grate magnets avoid material buildup. So workers spend less time removing collected debris by hand.

Grate Magnet Self-Cleaning

Simple, tool-free dismantling also allows fast access to the magnetic bars when needed. Minimizing production downtime.

5. Durable, Reliable Operation

Robust stainless steel assemblies protects magnetic rods from damage. This durable construction allows reliable separation even in harsh industrial environments.

Grate magnet housings also enable convenient field changes without dismantling equipment. So worn parts can be easily replaced to restore full function when required.

Careful design maximizes the working lifespan of grate magnet components. So you gain exceptionally reliable debris removal with limited maintenance needs over years of operation.

Manufacturer Examples and Applications

To give you a better idea of real-world grate magnet systems, here are some installation cases from leading manufacturers:

Food Production

In food factories, grate magnets maintain health and safety standards by extracting metal contaminants.

For example, Magnattack Global manufactures Magnattack® RE80® grate separators for flour, starch and milk powder lines. These remove iron fragments to ensure food purity at final packing stations.

Advanced 10-11,000 gauss neodymium magnets reliably filter particles as filtration points. While easy-clean scraper features help workers remove buildup during operation.

Industrial Material Handling

At waste recycling plants and mineral processing sites, heavy debris can cause conveyor breakdowns.

But systems like Industrial Magnetics’ IMRO Permanent Magnetic Separators protect equipment. Positioned over conveyor belts, powerful ceramic magnet grates grab and remove damaging metal pieces like digger teeth before they impact operations.

Liquid Processing

Grate magnets also prevent blockages, damage and corrosion in liquid piping systems.

Bunting Magnetics’ Strainer Magnets line strainers to intercept accumulated metal particles. This extraction keepsseparated iron from passing downstream at water treatment sites.

Manufacturing

Overhead magnetic grates provide inexpensive protection for expensive crushers.

As demonstrated in Eriez Magnetics’ RevX-E® self-cleaning grate installation above a rock crusher feeder. Iron scrap from the process is constantly captured and removed by powerful neodymium magnetic rods. This filtration stops damaging debris from entering the equipment.

Now you can see first-hand how major manufacturers are using grate magnets for fragmentation and purification across industries!

Frequently Asked Questions

Here are answers to some common grate magnet queries:

Are grate magnets expensive?

Grate magnets deliver exceptional value. With durable components and low operating costs, initial investments commonly pay for themselves within 12-18 months through uptime savings and reduced repairs.

How often should grate magnets be cleaned?

Self-cleaning variants remove most debris automatically. But weekly manual cleaning helps ensure optimum efficiency. Extracted material should be disposed of safely to prevent recontamination.

When should I replace a grate magnet?

Replacement timing varies. But checking magnetic strength every 2-3 years gives early warnings, allowing proactive rather than reactive servicing planning.

Can I install a grate magnet myself?

While smaller units can be installed DIY-style, professional fitting is recommended to ensure correct housing, mountings and magnet polarities. Otherwise, performance and safety could be compromised.

What industries use grate magnet separators?

Magnetic grates refine products and protect equipment across sectors like manufacturing, recycling, agriculture, pharmaceuticals, plastics, chemicals, ceramics and food handling.
