Uses for our rare earth ring magnets:
You may not think grains, like wheat and rice grown for human consumption are a perfect match for these neodymium ring 20mmx10mmx8mm epoxy coated magnets. Let us explain.
Harvest time for grains like wheat and rice is not the end, just the beginning of the end. For the grains it is the beginning of a long journey where they will encounter a lot of metal equipment and metal products, often helped along by magnets, including ring magnets.
In the first instance, the grain harvesters’ long horizontal threshing blades are often held securely, but not too securely in place with the assistance of powerful ring magnets. Helping with the regulated, rhythmic operation of huge scything blades, magnets also play another vital role. Ring magnets can act as a clutch, releasing their grip at a known force or pressure should the combine harvester’s valuable and finely machined grain cutting equipment jam on something strong, like tree stump or an animal carcass.
This ability of controlled slippage, or clutch function provided by magnetic engagement in an emergency, prevents in the initial stages at least, the transfer of mechanical power to the valuable blades while they are jammed. Direct power while the equipment is stuck could damage the harvester’s blades or its engine or both.
Ring magnets as a failsafe or circuit breaking system is highly valued by individuals or companies liable for the repair and downtime costs. The release force of ring magnets protecting combine harvesters is comparable to the release force required for the cook to remove a saucepan from its magnetic hold above the stove: they are both known in advance. A saucepan is required to boil or steam grains like wheat, oats and rice.
