Abstract
A process is proposed for the dewatering of compressibly dewaterable materials, in particular waste from the processing of paper material, which enables a very high degree of dewatering so that the waste can be readily disposed of, e.g. dumped. For this purpose, the material to be dewatered is initially pre-dewatered by gravity, and usually also by compression, in a transportation section (5). This pre-dewatering can take place in a continually operating feed section (7) through a perforated sieve jacket (10). The material then reaches a press section (6) in which a discontinuously working pressing device is in operation. Further improvements in the dewatering performance are possible by various embodiments of the corresponding pressing elements (13,14). The invention relates to both the process and the device for implemention of the process.
