  • Patent number: 6283301
    Abstract: A device and method for its use for separating particulate matter into fractional components. The device is characterized as being in the shape of a substantially vertical column having a feed port for feeding the particulate matter thereto. A top is provided for removing a light fraction of the particulate matter and a bottom for collecting a heavy fraction of the particulate matter and a longitudinal axis between the top and bottom portions of the column. Provision is made for drawing current of fluid such as air through the column which contains a channel characterized as having a series of angular bends with respect to the longitudinal axis, the bends being more acute to the longitudinal axis as the distance increases from the feed port.
