Decanter centrifuge is the fourth phase solids control equipment, also called Horizontal Spiral Centrifuge, Horizontal Decanter Centrifuge, and Screw Decanter Centrifuge etc. According to different rotating speed, it can be defined as middle speed, high speed and high speed VFD centrifuge. It is mainly use for recycling the barite, removing the fine solid particles sized in 2-7m, controlling the density and viscosity of drilling fluid to keep the drilling fluid performance.
