Magnetic Gears

The gears don't touch at all, they only interact magnetically, which makes them very unique. The gear ratio is determined by the number of magnets used in each rotor. If one rotor has 4 magnets and the other 16, that's a 4:1 gear ratio. 16 D62 on one rotor 4 DX22 on the other, makes a 4:1 ratio. There are four basic magnetic gear types:

Magnetite recovery in coal washing by high gradient

We have adapted high grade magnetic separation (HGMS) for magnetite recovery because of its insensitivity to coal/magnetite ratio and slurry density and its ability to capture fine magnetite at high velocity. An open vertical matrix able to capture 10 ..mu..m (avg. size) magnetite without entraining 2 mm coal has been incorporated in a 1.85 m
