<p>The present application relates to a flight mill comprising at least one twisted wire as the flight arm and methods of using the aforementioned flight mill. When compared to conventional flight arms, twisted wire flight arms have the advantages of being light, flexible, have a high tensile strength, are durable, have low kinetic friction and are cost effective to manufacture. The arm can be made from a single twisted wire or from a twisted pair of wires.</p> |
