Appts. for mixing and/or reacting viscous materials - comprises two rotating prismatic shafts to provide kneading action with external pressure source
Реферат: Mixts. having viscosity >50 p are prepd. in a mixer comprising 2 rotating shafts of prismatic cross section. These provide a kneading action when rotating in the same direction in circular channels. Residence time is controlled by an external press. source esp. pump and the shaft drive is common. For materials where viscosity changes during mixing either the shaft dia. is changed in steps or the shafts are tapered or inclined. An alternative cross-section is eccentrically mounted circular which can be made from commercial pipe, length is necessarily > dia.
