A screen apparatus for a vibratory separator, the vibratory separator having a basket, the vibratory separator for separating components of material introduced into the basket, the vibratory separator including a collection receptacle beneath the basket, the screen apparatus comprising

• screening material,
• a support,
• the screening material on the support,
• the support having a plurality of openings therethrough suitable for the flow of fluid therethrough, the fluid from the material introduced into the basket, the support having a plurality of fluid conducting channels therein at an angle to the plurality of openings so that fluid flowing into one of the plurality of openings may then flow into one of the plurality of fluid conducting channels and out from the support into the receptacle, and
• wherein the material introduced into the basket is drilling fluid with undesirable material therein and the screen apparatus is for separating drilling fluid from the material.

A screen mounting basket for a vibratory separator for separating components of material introduced into the basket, the vibratory separator including a collection receptacle beneath the basket, the basket comprising

• two opposed spaced-apart side walls having first ends and second ends, the first ends spaced-apart by an end wall connected to each of the side walls,
• a basket bottom opening between the two spaced-apart side walls,
• at least one side basket opening through one of the two spaced-apart side walls,
• at least one side basket screen over the at least one side basket opening,
• at least one basket screen over the basket bottom opening, and
• the at least one side basket screen and the at least one basket screen for separating a component from the material, component material separated by the at least one side basket screen not flowing through the at least one basket screen, the separated component material flowing into the collection receptacle.

A vibratory separator system for separating components from a liquid-solid mixture fed to the vibratory separator system, the vibratory separator system comprising

• a frame,
• a screen mounting basket on the frame,
• vibrating apparatus connected to the screen mounting basket for vibrating the screen mounting basket,
• the screen mounting basket comprising
• two opposed spaced-apart side walls having first ends and second ends, the first ends spaced-apart by an end wall connected to each of the side walls,
• a basket bottom opening between the two spaced-apart side walls,
• basket bottom screening apparatus at the basket bottom opening,
• at least one basket aperture not through the basket bottom,
• at least one aperture screen over the at least one basket aperture, and
• the at least one aperture screen and the bottom screening apparatus for separating a component material from the material introduced into the basket, material flowing through the at least one aperture screen not flowing through the bottom screening apparatus, the separated component material flowing into the collection receptacle, and
• wherein the liquid-solid mixture is drilling fluid with undesirable material therein and the component separated by the at least one aperture screen is drilling fluid.
