Abstract (en)
[origin: EP0431426A1] In a filter centrifuge, the filling level h is detected as a function of time during the filtering process and the differential quotient dh/dt is formed. The required dry centrifuging time for the filtercake is calculated from the differential quotient dh/dt at the point where the liquid enters the filtercake. <IMAGE>
