Abstract
An apparatus for discontinuous mixing of substances, one of which is a liquid and especially suitable for the mixing of thixotropic materials. The mixer has a high speed rotor which cooperates with a more slowly rotating stator. Both rotor and stator are provided with teeth disposed on mutually concentric circles. When the teeth move past one another, shearing slots are formed. The drive shaft carrying the stator also carries at least one radially extending arm on which is mounted a wall scraper whose angle of attack with respect to the wall may be changed by rotation about an internal axis.
