APPARATUS FOR DISINTEGRATING LARGE-SIZE POLYMERIC PRODUCTS Russian patent published in 2000 - IPC

FIELD: equipment for coarse disintegration of polymeric materials. SUBSTANCE: apparatus includes central and peripheral shafts with cutting discs mounted in housing. There are spacing sleeves between shafts. Apparatus also includes calibrating grate. Central shafts are mounted with possibility of rotation one towards another. Peripheral shafts are mounted higher than central ones in parallel with them. Cutting discs of each shaft are arranged between cutting discs of adjacent shaft. Each central shaft is kinematically joined with adjacent peripheral shaft by means of gearing. Ratio of diameter of spacing sleeve of central shaft to width of cutting member of disc is selected according to relation: 0.4KZ <D/l<0.64KZ, where K - gear ratio, Z- quantity of cutting members of disc of peripheral shaft, D - diameter of spacing sleeve of central shaft, l- width of cutting member. EFFECT: simplified design of apparatus, reduced disintegration cycle. 2 dwg
