A decanter centrifuge applies a force equivalent to several thousand G''s, which reduces the settling time of the particles. It is also favoured to maintain a large Gforce, which will result in an improved separation. The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process.
