ABSTRACT:
A molded body is produced on the basis of a raw material, the main content of which is material which is left after remolding pulp from paper and extraction of fibers from the pulp mass for remanufacturing of paper. This raw material which mainly consists of water, short fibers, and fine, mineral particles is drained by pressing in a first pressing stage between filter belts for production of a coherent body, is dried partially in a first drying stage is pressed and in a second pressing stage, and dried finally in a second drying stage. The invention concerns a similar method for separation of fibers and particles from waste water which results from repulping paper and reclaiming of fibers from the pulp mass for remanufacturing of paper, whereby an enviromental problem is solved in a very suitable way. A plant for manufacturing of a molded body on basis of the raw material mentioned comprises a largely horizontal filter unit (3, 25) for draining, a first pressing unit (7) for pressing the material between surfaces of filter belt, a first drying unit (8) for drying of the material, a second pressing unit (10) for pressing the material, and a second drying unit (11) for heat treatment of the material.
