Abstract
A method and apparatus for reducing the moisture content bound by capillarity in fiber cells of solid materials containing carbon. The material is ground and screened to form a loose sheet of the solid materials and/or sludges. The material is processed by screening and grinding methods for a plurality of hoppers for different grain sizes and grain size distributions. A thin layer of fines is spread as a first layer onto the spreading, feeding and filter belt, and a substantially thicker coarse material layer is formed as a second layer to form a sandwich of the material. The fines layer depth H.sub.F and coarse material depth H.sub.G of the sandwich correspond to the consistency and the proportion of the fines of the material. The sandwich formed is then carried by a belt into the pressure chamber of the filter press according to the dewatering cycle, while simultaneously the squeezed-out dry material is carried away.
