  • In-line classifier for powdered products
    Patent number: 7540386
    Abstract: A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.
    Type: Grant
    Filed: August 1, 2007
    Date of Patent: June 2, 2009
    Assignee: Eastman Chemical Company
    Inventors: Lawrence Carvagno, William L. Cook, Ronald Keith Dailey, Jacob Anthony Southerland
