Grate magnets: common questions
What is a grate magnet used for?
Catching fine iron and tramp metal in dry, free-flowing product at a hopper or chute, before it reaches machines or the final pack.
How strong are your grate magnets?
Rare-earth grate designs we quote typically sit around 10,000–13,000 gauss at the tube face. The real figure depends on build and air gap, so we confirm it per application.
Single row or double row?
Double row gives two chances to catch iron and suits finer contamination or higher flow. Send your product and flow rate and we will advise.
Can you make it to my hopper size?
Yes. Standard housings run 100–400 mm; loose grates are made to your opening. Send the inside dimensions or a photo.
Is a full-weld grate available?
Yes, built to order for food and pharma lines. Not every model is full weld, so confirm the build at quotation.
How do I clean it?
Loose grates are lifted and wiped. In a housing, pull the drawer out by its handles and wipe the tubes into a catch box. Easy-clean versions slide the tubes out of sleeves.
