Distribution of particle sedimentation thickness under constant relative centrifugal force in rotating separation system using wireless electrical resistance detector

The demand for high separation efficiency needs an advanced device that can be installed in the separation machinery. Parameters in the separation system, such as feeding flow rate and rotational speed, influence the sedimentation formation. A wireless electrical resistance detector (WERD) was devel...
