Abstract (en)
[origin: US5566903A] Roller mill and milling tool for milling suspended fibrous material. For particularly economical milling of suspended fibrous materials, roller mills and milling tools are utilized in which the radial extent of the working surfaces deviate from the state of the art in that the raised areas, acting in the manner of knives, form working surfaces which extend radially outwardly to a lesser extent than the base surfaces of the milling tools or the corresponding milling tool carriers, whereby it is feasible to utilize the shorter raised areas on the stator side, the rotor side, or on both sides, thereby, via these measures, achieving a particularly economical and uniform comminution.
