## Torque & Speed How Much Is Enough? | Plastics Technology

High-speed, high-torque machines are often—but not always—one or two barrel sections longer than a conventional twin-screw. The highest screw speeds apply only to smaller screw diameters. W&P's ZSK MegaCompounders go up to 1200 rpm but only in sizes up to 70-mm diam. At 133-mm, maximum speed is 1000 rpm.
