Twin-Shaft Kneader Reactor

Compared to the single-shaft units, SK3020 Twin-Shaft Kneader Reactors offer even better mixing and kneading reaction, more effective self-cleaning properties and the more efficient renewal of boundary layers. These and many other features make the SK3020 Twin-Shaft Kneader Reactor the best choice for processes such as:

  • Bulk polymerization

  • Polycondensation

  • Drying

  • Dissolving

  • Sublimation

  • and others

SK3020 Twin-Shaft Kneader Reactor, 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. SK3020 Twin Shaft Kneader Reactors are also nearly 100% self-cleaning.
