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.
Claims19
A device for separating particulate matter into fractional components, said fractional components having distinguishable physical characteristics enabling said fractional components to be separated by subjecting them to varying fluid velocities, said device comprising a substantially vertical column, a feed port for feeding particulate matter thereto, a top for removing a light fraction of said particulate matter and a bottom for collecting a heavy fraction of said particulate matter and a longitudinal axis between said top and bottom, means for drawing a current of fluid through said column, and a channel configured within said column, said channel being characterized as a series of angular bends with respect to said longitudinal axis, said bends being more acute to said longitudinal axis as the distance increases from said feed port.
A method of separating particulate matter into fractional components, said fractional components having distinguishable physical characteristics enabling said fractional components to be separated by subjecting them to varying fluid velocities, said method comprises feeding said particulate matter through a feed port and into a channel configured within a substantially vertical column, said column having a top, a bottom and a longitudinal axis between said top and bottom, and further being characterized as having a series of angular bends with respect to said longitudinal axis, said bends being more acute to said longitudinal axis as the distance increases from said feed port, drawing a current of fluid flow through said channel and collecting a light fraction of said particulate matter from the top of said column and a heavy fraction of said particulate matter from the bottom of said column.
