<p>The present invention relates to waste screening apparatus and methods, particularly but not exclusively for screening waste material streams for recycling and the like. It also relates to an apparatus for separating portions or fractions of a waste material stream, generally to facilitate recycling of one or more of said fractions, and a method therefor; and to combinations of same. One screening apparatus comprises: (a) a first screen frame comprising at least two sides and a plurality of first cross members thereinbetween; (b) a second screen frame comprising at least two sides and a plurality of second cross members thereinbetween, the second cross members being laterally interspaced with the first cross members; (c) a plurality of flexible screen mats located between at least some of the first cross members and adjacent second cross members; (d) a first driver to cause the first screen frame to oscillate; and (e) a second driver to cause the second screen frame to oscillate; wherein the second driver is independent to the first driver.</p> |
