Case Study: XR Screens Outlast and Outperform TBC Screens

Challenge: M-I SWACO was supplying the operator with both XR and TBC screens on Brandt brand VSM 300^ shakers, and a trial was scheduled to determine the better screen for the drilling conditions so that improvements in inventory and logistics could be achieved. The trial was designed to evaluate: Cost per hour; Screen life (hours) relative to screen position; Conductance (flow capacity); Difference in Cut Point – Particle Size Analysis

Result: XR Screens demonstrated an overall cost reduction of up to 70% over TBC screens: Front screen life: XR screens showed extremely low wear rates, and life was six to seven times longer than TBC screens; Back Screen life: Testing showed XR screens had 4 and 5.2 times longer life than the TBC. The dramatic difference in screen life is a result of the XR screen’s proprietary design. The use of larger wire diameters increases durability and extends screen life, resulting in fewer required screen changes and reduced overall cost even when compared to screens with significantly lower unit cost.
