The TEX 44 Alpha III corotating twin-screw extruder from JSW (U.S. operation in Novi, Mich.) is aimed at compounding, masterbatch production, devolatilizing, and underwater pelletizing, among other applications. The machine, which will debut at next month’s K 2013 Show in Düsseldorf, offers 36% more torque than previous designs. This gives compounders more throughput while also saving energy by processing at lower melt temperatures and reduced screw speeds. A wider processing window at higher torque also provide for more aggressive kneading and mixing.
The new machine features a mechanical torque limiter, which immediately cuts the connection to the screw in the unlikely event of malfunction or critical process situation, protecting the equipment from expensive damage and downtime. The new drive system includes an infinitely variable three-phase motor. It can use a water cooling system, which is quieter than air cooling.
JSW’s Exanet 64-bit RISC high-speed control system features a 15-in. color LCD touchscreen.This control system can integrate auxiliary equipment from the feeding and mixing system downstream to the pelletizer.
