摘要

Improvements in the construction of disc mills especially for grinding and dissolving fibrous materials for the paper industry, which contain at least a pair of grinding discs which, in a housing with central supply and spiral outlet, rotate relative to each other and whose surfaces of work have depressions, arranged concentrically, displaced from each other, annularly, as well as ribs, respectively blades, directed in an approximately radial direction, characterized in that the upper edges of the ribs, respectively of the blades, run below the surface, which is determined by the annular ridges, which lie between the depressions.
