ABSTRACT:
A dewatering machine comprises an integral and cooperative combination of a vacuum filter of the rotary drum type and an expression device of the diaphragm type. An intermittently-indexed endless filter medium belt carries a sheet of filter cake to the expression device after the cake is formed on the vacuum filter. The belt indexing action is coordinated with pressurization of the expression device so that the filter drum is indexed only when the diaphragm is relaxed and the pressurization is effected only at such times as the drum is not being indexed.
