Apex mixing—high shear. Quality parts and service. Language change-over. Intermesh: a high shear region, independent of the degree of screw fill; it is a high-intensity mixing zone between the screws where the screws "wipe" each other. • An anti-seize compound should be used every time elements are assembled on a shaft. Cross-sectional area and internal geometry of the die relative to the mass flow rate determines the pressure generation requirement, which will directly influence melt temperature and performance for heat-sensitive products (11). Co. : Amsterdam, The Netherlands, 1978; ISBN 978-0444416292. Screw elements that accentuate extensional mixing and planar shear effects are dispersive in nature, as compared to elements that facilitate melt divisions/recombinations, which are more distributive and therefore useful for mixing heat and shear sensitive materials. Gearboxes also reflect the latest technologies available and facilitate screw rpms of 1200+ and short process residence times—even 5 s or less is possible. Analysis of Mixing in Co-Rotating Twin Screw Extruders through Numerical Simulation. A Unified View of Modeling Flow in Counter-rotating Twin Screw Extruders.
