Abstract
A screening arrangement in a vibrating screen for screening of material, such as crushed stone, gravel or the like. The screening arrangement is a cross-tensioned or longitudinally tensioned screening media including elements arranged on top of the screening media for stirring or mixing the screened material, the stirring elements being raised portions, which are arranged transversely to the travel direction of the screened material.
Claims11
A screening arrangement in a vibrating screen that screens material comprising:
- a cross-tensioned or longitudinally tensioned screening media having
- a longitudinal beginning portion,
- a longitudinal end portion opposite the longitudinal beginning portion, wherein the screened material enters at the longitudinal beginning portion,
- a travel direction of the screened material defined transversely to the longitudinal beginning portion and the longitudinal end portion,
- at least two sides extending transversely to the longitudinal beginning portion and the longitudinal end portion, and
- a coupling at each of the at least two sides that secures the screening media;
- and
- a plurality of raised portions arranged on a top surface of the screening media that stirs or mixes the screened material, each of the plurality of raised portions arranged transversely to the travel direction of the screened material, each of the plurality of raised portions including,
- a first slope that rises along the travel direction of the screened material,
- a top portion at a higher end of the first slope, and
- a second slope steeper than the first slope that descends from the top portion.
