Extruder features unique screw shafts

NP_Leistritz-01.jpgThe corotating twin-screw ZSE-18 extruder from Leistritz uses hammered and splined screw shafts to reportedly increase torque more than 50% over keywayed shaft designs. Faster models feature a 10-kW drive for 1200-rpm screw speeds, and the extruder?s drive system also uses four 2.5-kW motors integrated with the gear motor. Modular barrels come in five diameter increments and feature electric cartridge heaters and air and liquid internal bores for cooling. A side stuffer can be added to introduce fillers and fibers. Throughputs range from 1 to 80 lb/hr, and applications can include research and development, pilot plant sampling, and small-scale production.
