ABSTRACT:
A process for screening materials as a function of particle size differences by feeding the materials onto one side of a substantially planar screen and vibrating the screen by producing a translational screen oscillation in directions normal to the screen plane and a torsional screen oscillation about an axis normal to the screen plane so that each point of the screen moves in a helical path. Screened material is collected at the other side of the screen and screened retentate is transported by the torsional screen oscillation to an exit port at a location spaced from the axis of torsional oscillation.
The process is particularly applicable to shipboard or other mobile use, since the spring stiffness provides good structural support under tilt or side acceleration conditions.
