    Test material was a limestone fraction of 500 um. The metal screen had a mesh size of 250 um. As discussed above, for vibration dewatering, the inertial force and drip condition must be taken into consideration and, for centrifugal dewatering, they are neglected. The significance of these two criteria are clearly shown in Fig.
