Compared to the single-shaft units, LIST Twin-Shaft KneaderReactors offer even better mixing and kneading behavior, more effective self-cleaning properties and the more efficient renewal of boundary layers. These and many other features make the LIST Twin-Shaft KneaderReactor the best choice for processes such as, Bulk polymerization Polycondensation Drying Dissolving Sublimation and others In a LIST Twin-Shaft KneaderReactor, the high-torque shafts are designed to rotate in either the same direction or in counter-direction. In both cases, the kneading elements on the shafts intermesh to generate intensive surface renewal and mixing. At the same time, shear rates remain low. LIST Twin Shaft KneaderReactors are also nearly 100% self-cleaning. Typical design specifications: Volume: 3 … 10´000 l Operating pressure: 0.001 ... 10.0 bar (a) Operating temperature: -100 ... +400 °C Operation mode: Batch or Continuous Installed Power: ... 1.5 MW Torque: ... 500 kNm Drive: Hydraulic...

The extremely versatile LIST Single Shaft KneaderReactors are in successful operation in a wide range of industrial-scale process applications, e.g. Crystallization Drying Dissolving Main Evaporation Devolatilization Torrefaction and others The inovative design features a single mixing shaft whose kneading elements intermesh with counter-hooks attached to process housing providing a self-cleaning effect. The rotation speed and geometry of the mixing shaft and kneading elements are customized designed to optimize the prozess efficiency. With an operating volume up to 20 m3, it provides the capacity to handle largest production capacities. Typical design specifications: Volume: 7 … 20´000 l Operating pressure: 0.001 ... 16.0 ... 100 bar (a) Operating temperature: -100 ... +400 °C Operation mode: Batch or Continuous Installed Power: ... 2.5 MW Torque: ... 500 kNm Drive: Hydraulic drive units or electric motor with or without frequency converter Shaft seal: Stuffing box or...
