METHOD OF PRODUCING FITTINGS FOR MECHANICAL PROCESSING OF WATER-CONTAINING PAPER-FIBROUS PULP Russian patent published in 2008 - IPC D21D1/30

Abstract RU 2329343 C2

FIELD: mechanics.

SUBSTANCE: invention relates to manufacture of the fittings used, for example, in refiners intended for pulp beating stage. The fittings produced in compliance with this invention consists of base (1) with adjoining mask (3) and processing elements (5). Processing elements (5), for example, plate-type knives are fitted into mask (3) furnished with appropriate holes (4). Processing elements (5) and mask (3) are soldered together at high temperature with mask (3) being attached to base (1).

EFFECT: simplification of production and an opportunity of using of suitable strong materials for highly-loaded processing elements.

28 cl, 8 dwg
