Decanter Centrifuge

What is Decanter Centrifuge

Decanter centrifuge is the 4th solids control equipment in whole drilling mud system&peroid; It is used to process drilling mud discharged from desilter cones or mud cleaner&peroid;

Separation point of decanter centrifuge is as fine as 2~7 microns. According to different rotation speed, there are high-speed and middle-speed centrifuges. It really plays an important role in lower mud density and bentonite recovery.

How To Choose a Decanter Centrifuge

  • Mudflow: The flow rate is related to bowl size and rotation speed.
  • Industry: Use it in oil drilling, water drilling or HDD?
  • Depth: Drilling depth is another issue considered during selection. Usually, depth over 3500m, the high-speed one should be utilized.
  • Drilling fluid property: Viscosity, mud base, and so on. Kindly confirm the applicability from mud engineer or centrifuge supplier.
  • Function to achieve: Separation, or recycle?
