Rubber compounds are produced in a discontinuously working internal mixer with the addition of components such as rubber, fillers and other additives.

Rubber compounds are almost completely produced in a discontinuously working internal mixer. This offers, for example, the advantages of high flexibility and the ability to accept a variety of different dosing components (bales, powder, oil, etc.) [1]. Due to an insufficient understanding of processing and materials, the material potential is often not fully exploited in the production of elastomer products and elastomer components may be oversized [2]. This represents a critical factor, particularly in relation to improve resource efficiency [3].
