COMPOSITE POLYMERIC MATERIAL SCREW MIXER Russian patent published in 1999 - IPC

FIELD: rubber industry, shoe making, civil engineering; preparation of homogeneous viscous-flow polymeric composites. SUBSTANCE: screw mixer has housing and two rotor placed inside for rotation in one direction. Rotors are made in form of shafts with auger members and with cams. Cams are mounted in tandem after auger members along screw line at angle relative to each other. Cams have side and end face pressure surfaces. Mixer has also mechanism with main and additional driving and driven gears. Gears are installed on shafts one after the other. Driving and driven gears are installed with alternation on each shaft. Pair of meshed gears located in zone before polymeric composite discharge zone is essentially vane mixers - gears. Mixers-gears are installed for free rotation on shafts and are mechanically coupled with separate drive. EFFECT: enhanced effect of mixing and quality of mix. 3 dwg
