A pulper is used to comminute and suspend paper stock. The pulper includes a container that is open at the top and has a cylindrical side wall and a driven rotor, which is arranged eccentrically with respect to the center of the container. The bottom of the container can be provided with one or more truncated cones.

Pulper for comminuting and suspending paper stock and its use

Process for dissolving used paper including adjusting a content of solid particles of used paper to a range between about 15 and 35%, kneading the used paper with a specific work of at least about 10 kWh/t, diluting the kneaded used paper to a content of solid particles below about 6%, separating non-fibrous contaminants with wet screening, adjusting a solid material content to less than about 3%, and separating heavy particles with at least one hydrocyclone.

Process and device for decomposing fibrous material in an installation including a drum having an inner wall, a first end, and a second end, a displacer having an outer wall positioned inside the drum, and a processing channel formed between at least a portion of the outer wall and at least a portion of the inner wall. The process includes pouring fibrous material to be decomposed into the drum, relatively moving the outer wall relative to the inner wall in a peripheral direction of the drum, and mechanically processing the fibrous material in the processing channel.

Process and device for the decomposition of fibrous materials

Process for modifying an existing breast box for a paper or cartonmaking machine as well as an intermediate portion for carrying out the process. During the fabrication of a breast box for a paper or cartonmaking machine an intermediate portion is interposed between a supply apparatus and a downstream guiding device, with the material suspension flowing through this intermediate portion wherein, via supply lines, located on the intermediate portion, a liquid is added which differs from that of the suspension stream. Particularly, in this manner, already existing breast boxes can be converted, to water dilution technology, with this invention setting forth special embodiments of differing intermediate portions that can be utilized therefor.
