Screen assemblies for a vibratory separator and methods of using them, the screen assemblies in one aspect including a first screen portion having a first end and a second end spaced apart from the first end, a second screen portion adjacent the second end of the first screen portion, the second screen portion projecting down from the second end of the first screen portion.

Screen assembly for vibratory separators

A screen assembly for a vibratory separator, the screen assembly having a first screen portion having a first end and a second end spaced apart from the first end, and a second screen portion formed integrally of or connected to the second end of the second screen portion. A screen assembly with a first portion of screening material and a second raised portion of screening material, the second raised portion extending from a material introduction end of the screen assembly to a material exit end thereof, the raised portion, in one aspect, culminating in an apex above the first portion of screening material.

A screen assembly for a vibratory separator has been invented, which, in certain aspects, has at least two ridge-valley series of screening material with a plurality of alternating ridges and valleys of screening material, and at least one ridge-valley series of screening material offset from at least one other ridge-valley series of screening material. A screen assembly for a vibratory separator has been invented, which, in certain aspects, has at least one ridge-valley series of screening material, said ridge-valley series including a plurality of ridges each ridge between valleys of a plurality of valleys, and each ridge having a first end spaced apart from a second end, said first end having a top wider than a top of second end.

Shaker screens and methods of use

A screen assembly for a vibratory separator has been invented, which, in certain aspects, has at least two ridge-valley series of screening material with a plurality of alternating ridges and valleys of screening material, and at least one flat area of screening material adjacent at least one of the ridge-valley series.
