Abstract

A concentrator press includes a pair of rotatble press rolls (1) which coact with one another. The press rolls have apertured or perforated mantle surfaces (5) for removing liquid from a liquid-drenched material (3) to be concentrated and advanced between the press rolls. A part of the peripheral surface (5) of each press roll (1), including at least those regions in which the press roll acts on material undergoing concentration, is surrounded by a respective endless filter-cloth web (6, 7) which also runs around at least one direction changing roller (10; 10, 17, 18) at a distance from its associated press roll (1) and the still not concentrated, liquid-drenched material (3). The filter-cloth webs (6, 7) extend generally parallel with each other downstream of the press nip, to a concentrated material delivery station (15, 16).
