R. Uphus*, S. Wachter and O. Skibba VMI-AZ Extrusion, Runding Germany
An extruder gear pump system is presented for the final mixing step. Feeding of the base compound from the first mixing step - done in an internal mixer - with dosing of the crosslinking chemicals into an extruder / gear pump combination gives the opportunity to get a constant high quality of the compound. Together with inline-straining of the compound this saves an additional step in producing the rubber compound.
