Research on Fill Factor of Internal Mixers

摘要

With the same recipe and technological conditions, experimental research on fill factor about rubber compound of all-steel radial tire was conducted in four types of X(S)M-1.7L mixers: intermeshing rotor mixer, variable intermeshing clearance mixer, shearing rotor mixer and variable shearing clearance mixer. Based on the summary and analysis of experiments, the authors discussed the influence of fill factor on performance of internal mixers and physical and mechanical properties of the rubber compound. And the optimal values of fill factor of different types mixer were determined.
