For the GlobeCore USB-3 bitumen modification unit, the high-speed mixer (the impeller in the intermediate tank) and the colloid mill operate at typical industrial high rotor speeds – on comparable units the mill shaft runs around 6650 rpm, with the electric drive shaft around 2770 rpm. This gives a sense of the high-speed mixing regime inside the unit, even though exact mixer speeds can vary by configuration and are set to ensure good dispersion before milling. If you need precise rpm values for your specific USB-3 variant, the manufacturer can provide detailed specs based on motor and drive choices.
