Rates through a 3+ RingExtruder far exceed expectations compared to a twin screw extruder. 12 screws instead of 2 screws suggests 6 times the throughput of a twin screw extruder equipped with screws of equal diameter.

However, a RingExtruder 3 model with only 30 mm diameter screws commonly melts and pumps 1800-2000 lb/hr of an engineering thermoplastic and 3000 lb/hr of a midrange MI polyolefin. This is far more than 6 times what is typical when using a 30 mm twin-screw extruder!
