Abstract

Powderous, granular, and/or liquidous substances such as thermoplastic or elastomeric materials are mixed with each other or with fillers, additives, etc. in that the mixing operation is continued until a predetermined amount of mixing work has been expended. The mixing operation can be controlled as to its entire duration on that basis as well as with regard to completion of intermediate steps.
