PLANT FOR GRINDING OF FIBROUS MATERIALS Russian patent published in 2003 - IPC

FIELD: pulp-and-paper, chemical, construction and other industries. SUBSTANCE: plant includes body with treatment chamber having grinding accessories, rotor mounted on drive shaft, and stator, inlet and outlet pipes and impeller also mounted on rotor shaft, with impeller blades facing inlet pipe located at level of blades location. Blades are cantilevered on axles located on periphery of impeller disk. Distance of blade free edge to internal surface of treatment chamber does not exceed blade thickness half, and to axle of inlet pipe, not more than two thicknesses of said blade. Technical result consists in maximum utilization of jet energy in hydrodynamic treatment of materials. EFFECT: intensified grinding process and higher quality of fibrous material grinding. 3 dwg
