12-MSS (Mini Separation System)


The Derrick 12-MSS offers ultra-fine separation in a very small footprint. Coarse mesh scalping is achieved by the lower deck outfitted with long life, high open area, fine urethane screen panels. Screen underflow is then processed through ten 4’’ Derrick desilting cones. Cone underflow is routed onto the upper fine screening deck with 140 to 200 mesh screens. Cleaned fluid (less than 1/2 of 1% sand) is returned to excavation.
