Patent ID: 6868972

Claim:
A vibratory separator comprising basket apparatus for holding screening apparatus, at least one upper screen apparatus in the basket, the at least one upper screen apparatus having a fluid exit end, the at least one upper screen apparatus for screening fluid introduced thereon so that a first part of the fluid flows through the at least one upper screen apparatus and a second part of the fluid flows off the fluid exit end of the at least one upper screen apparatus without passing therethrough, at least one lower screen apparatus in the basket below the at least one upper screen apparatus, the first part of the fluid flowing down onto the at least one lower screen apparatus for screening thereby, flow diffusion apparatus mounted below the fluid exit end of the at least one upper screen apparatus and above the at least one lower screen apparatus, at least a portion of the flow diffusion apparatus projecting beyond the fluid exit end of the at least one upper screen apparatus so that the second part of the fluid flowing down from the at least one upper screen apparatus is intercepted by and flows onto the flow diffusion apparatus and is diffused down onto the at least one lower screen apparatus, vibrator apparatus for vibrating the basket and the screen apparatus therein, wherein the flow diffusion apparatus is made from material from the group consisting of plastic, metal, fiberglass, wood, composite material, cermet, and ceramic, wherein the flow diffusion apparatus comprises a main part with a central body, a first side and a second side, the first side connected to and projecting upwardly from the central body part, and the second side connected to and projecting upwardly from the central body.
