The belt-type drainage tester was further developed and tested. Pretreatment of the pulp suspension prior to dewatering now includes both controlled addition and mixing of chemicals and temperature control. Foil-angle modification of the suction slits on the belt was tested. Selected results of experiments with varied test parameters are presented, in particular, the effect of the pulsation rate on z-directional filler distribution, and experience of attempts to simulate a pilot machine by imitating its suction profile. The results indicate that high pulsation frequencies are necessary for producing realistic z-directional filler (or fines) distributions. Experimental simulation of dewatering on the wire-section of a pilot machine is promising, but there are still problems to be solved.
