Centrifuges for drilling generally include high-speed centrifuges and medium-speed centrifuges. 1000-2000r/min is a medium-speed centrifuge, and higher than 2000r/min is a high-speed centrifuge.
The choice of centrifuge is affected by the particle size of the solid phase particles to be separated, the diameter of the centrifuge drum, the highest speed, and the separation factor. The sedimentation centrifuge commonly used on the drilling site is the difference in the density of solid and liquid as the separation basis, mainly used to remove the solid phase material in the drilling fluid of 2-10μm, and is the last level of drilling fluid solid control equipment.
