An installation of multiple screening machines or a single screening machine with multiple feed points, like the Derrick^® Stack Sizer^®, requires a well-designed flow distribution system. Custom engineered to suit customer requirements, Derrick flow distributors split slurry flows into various identical streams in terms of mass flow, volumetric flow, slurry density, and particle size distribution.

Typical round flow distributor consists of an open cylindrical tank design with a center feed well surrounded by multiple discharge compartments around the circumference.
