For improved disintegration of the polymer in the bitumen with the high shear mill, the polymer and bitumen mixtures have to be pumped to the mill without waiting. When all bitumen and polymer is loaded into the tank, the PLC starts to pump out the two components via P2 (mill feeding pump) and D (high shear mill) to the PMB service tanks.
