from The Century Dictionary and Cyclopedia

  • n. In mining, a machine which effects the separation of minerals according to size or density by air, either by pulsating rising currents (see air-jig); or by a continuous blast, as in the Edison, Hochstedt, and other dust-separators; or by projecting the particles to be separated by mechanical means into still or moving air, as in the centrifugal separators of the Pape-Henneberg and Clarkson-Stanfield types.


Sorry, no etymologies found.


  • Between the above two, an open-circuit mechanical air-separator mill requires more auxiliary equipment and space but requires less power per ton of cement ground.
