Beschreibung
Zusammenfassung:	A screen assembly for a vibratory separator, the screen assembly comprising a ridge-valley series of screening material (14, 16; 31, 32, 33, 34; 43) having a plurality of alternating ridges (18; 41) and valleys (20; 42) and two spaced apart ends having ridge openings below the ridges, said openings covered with screen or mesh material characterised in that said openings are covered with screen or mesh material (14; 44) in a generally bulbous shape. A vibratory shaker including the screen assembly of the invention. A method for screening using the vibratory separator of the invention said method comprising the step of vibrating said ridge-valley series of screening material, pouring a particle laden fluid on to one of said ridge-valley series of screening material thereon, allowing fluid and predetermined size particles therethrough, and vibrating particles larger than said predetermined size to a far end of one other of said ridge-valley series of screening material.
