  2. Eddy current separator - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_separator

    An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals. [1]

  3. Magnetic separation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_separation

    The new forms of magnetic separation included magnetic pulleys, overhead magnets and magnetic drums. In mines where wolframite was mixed with cassiterite , such as South Crofty and East Pool mine in Cornwall or with bismuth such as at the Shepherd and Murphy mine in Moina, Tasmania , magnetic separation is used to separate the ores.

  4. Harvard Mark III - Wikipedia

    en.wikipedia.org/wiki/Harvard_Mark_III

    The Mark III used nine magnetic drums (one of the first computers to do so). One drum could contain 4,000 instructions and has an access time of 4,400 microseconds; thus it was a stored-program computer. The arithmetic unit could access two other drums – one contained 150 words of constants and the other contained 200 words of variables.

  5. High-intensity magnetic separator - Wikipedia

    en.wikipedia.org/wiki/High-intensity_magnetic...

    Magnetic separators that used permanent magnets could generate fields of low intensity only. These worked well in removing ferrous tramp but not fine paramagnetic particles. Thus high-intensity magnetic separators that were effective in collecting paramagnetic particles came into existence. These focus on the separation of very fine particles ...

  6. Mechanical screening - Wikipedia

    en.wikipedia.org/wiki/Mechanical_screening

    Mechanical screening, often just called screening, is the practice of taking granulated or crushed ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.

    GEA Westfalia Separator Group GmbH with head office in Oelde, Westphalia is a German manufacturer of separators and decanters which is part of the GEA Group.The company develops procedures and processes for the mechanical clarification and separation of liquids for the food industry, chemicals, pharmaceuticals, biotechnology, energy, shipping and environmental technology.

  8. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

  9. Permanent magnet motor - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet_motor

    Alnico is a NRE permanent magnetic material used in permanent magnet motor applications such as magnetic speed and flow sensors, electric generators, and consumer goods. These magnets exhibit weaker performance in comparison to NdFeB and SmCo counterparts but still maintain high coercivity and are far cheaper due to their lack of rare earth metals.
