Abstract
In a dewatering press having a number of rotors rotatable in a cylindrical press housing with an inlet channel defining an inlet for a humid mass into the housing, a mechanism for equalizing the amount of mass fed to the inlet channels. A screw feeder is associated with each inlet channel, and equalization is accomplished by providing opening communication between the screw feeders at their pressure ends, adjacent the inlet channels. A module having a conduit associated with each inlet channel, and a cross over tunnel at the portion of the module adjacent the press housing, is disposed between the feeder screw housing and the press housing.
