Abstract: A basket system for a shale shaker includes a front, solids discharge end and a rear, feed end, spaced apart by opposed first and second sides. The feed end includes a fluid retaining wall. A first screen deck frame is mounted or mountable to the basket for supporting a screening surface and forming a first screen deck in use. The screening surface of the first screen deck has a lower, feed receiving end that is proximal to the fluid retaining wall at the rear end of the basket and a distal, higher, solids discharge end at the front end of the basket. The basket further includes at least one mounting for mounting at least one additional screen deck frame above or below the first screen deck frame.

Abstract: A shale shaker includes a basket having a front, solids discharge end and a rear, feed end spaced apart by opposed first and second sides. The basket includes a lower, first, screen deck and an upper, second, screen deck directly above the first screen deck. The screening surfaces of the screen decks are spaced apart, by a vertical spacing of from 20 mm to 250 mm. There is a cavity above the feed receiving end of the first screen deck, in direct fluid communication with the space between the screening surfaces of the first and second screen decks ( ) that only receives feed that has passed through the upper, second, screen deck. The cavity extends to higher than the extreme end of the screening surface of the second screen deck, at its feed receiving end.
