Abstract
FIELD: applicable in wood-pulp and paper industry for milling chips and various fibrous semifinished products. SUBSTANCE: fittings of disk mill have rotor and stator disks 1 with a set of separate sectors with cutting knives installed with possibility of their replacement. Each sector is made of several parts 2 and 3 manufactured by the method of powder metallurgy from wear-corrosion- resistant materials. Embedded in each part 2 and 3 during pressing are parts in form of bushings 5 with collars 6 with the help of which sectors are secured by means of bolts 4 to disks 1 of rotor and stator. Bushings 5 are made of low-carbon steels which are not hardened during heat treatment. Collars 6 of bushing 5 are made with adverse gradient of 3-10 deg. Each sector nonworking side has axial projections and disks 1 have axial recesses corresponding to projections in their shape. In case of failure of separate parts of sectors, they are replaced with new ones. Sectors are light in weight and wear-resistant in operation due to the fact that they are made of powder materials. EFFECT: higher operating characteristics of the fittings due to durability of sectors and stability of the milling process, and also provision of replacement of parts of sector in case of its wear. 3 cl, 6 dwg
