PCT No. PCT/SU84/00066 Sec. 371 Date Jul. 11, 1985 Sec. 102(e) Date Jul. 11, 1985 PCT Filed Nov. 6, 1984 PCT Pub. No. WO85/02558 PCT Pub. Date Jun. 20, 1985.A disintegrator according to the invention comprises a milling chamber (1) accommodating rotors rotating in opposite directions relative to each other. The rotors comprise carrier discs (4, 11) and disintegrating wheels (6, 13) concentrically mounted thereon. Each disintegrating wheels (6 or 13) comprises a cylindrical shell (17) having openings (18) and milling bodies (19) provided behind the openings on one side thereof. In addition, the wheel is also provided with a pair of guard members (20, 21) installed in mutually perpendicular planes which are designed to prevent a material (15) being disintegrated from getting into spaces between the carrier discs (4, 11) and disintegrating wheels (6, 13). One guard member (20) comprises a ring mounted on the periphery of the shell (17) on the inner side thereof to extend around the group of the milling bodies (19). The other guard member (21) comprises a cylindrical ring secured to the inner side of the respective carrier disc (4, or 11) opposite to the first guard member (20), the outside diameter thereof being substantially equal to the inside diameter if the shell (17) and the height being substantially equal to the amount of space between the carrier disc (4 or 11) and the end face of the shell (17). |
