Abstract
A solids flow distribution apparatus is disclosed for use with two or more solid separation devices, such as shale shakers. The appartatus includes a plenum in communication with a source of flow of solids and liquid, such as from a drilling rig's mud system. The plenum includes lower outlets positioned adjacent inlet zones for each solid separation device. Valves are positioned across the lower outlets for regulating the quantity of solids and liquids that flow into the inlet zones of each solid separation device. A variable distribution apparatus is included within the plenum adjacent the flow inlet for regulating the proportion of solids directed towards each solid separation device.
