The Flo-Line Primer 258™ utilizes a screen belt conveyor system to separate hydrated clays and large drilled cuttings from drilling fluid. This allows finer screens to be installed on the primary shakers, leading to lower dilution and operating costs. The Flo-Line Primer 258 is used in place of scalping shakers. The synthetic screen belt is available in 5, 10, and 20 square mesh weave.
