Highly Efficient Mixing with Tangential Internal Mixers

Abstract

Tangential internal mixers have been used successfully for over 100 years to process rubber compounds. Continuous development of the mixer has enabled the mixing process to be made ever more effective. The present article describes an often unexploited potential in terms of process engineering. By deliberately adjusting friction and the position of the rotors, further potential can be leveraged at different mixing stages. This additional function can be retrofitted on to existing lines at reasonable cost. Modern multi-layer power train concepts also help to reduce operating costs for the mixing line.
