Centrifuge is the key equipment for handling ultra-fine and harmful solid phases in drilling fluids,it can separate and recover the solid phase with a particle size greater than 5μm and quickly recover the density of the drilling fluid, there by increasing the drilling speed. It is an ideal drilling fluid purification equipment for deep wells and horizontal wells.This machine is mainly used to control the density and viscosity of the drilling fluid and reduce the solid content of drilling fluid, remove the harmful solid phase, recycling barite, and the secondary recovery of the cyclone bottom to ensure the excellent performance of the drilling fluid, improve drilling speed.
