Description:
The Gloucester 35250R2 3.5” Single Screw Extruder is a high-performance, industrial-grade extrusion system, designed for efficient polymer processing in sheet extrusion, compounding, and recycling applications. This system features a 3.5" diameter screw with a 32:1 L/D ratio, providing consistent material processing and superior melt quality.
The electrically heated, air-cooled, non-vented barrel operates at an approximate 65” centerline height and is Contra-Cool ready (blower not included). The 18.17:1 reduction ratio gearbox is directly driven in a wraparound configuration by a 100 HP Baldor DC motor, offering smooth and reliable extrusion performance. The Saftronics SCR control system ensures precise speed and torque control for optimized extrusion efficiency.
For temperature regulation, the system includes an oil pump with a heat exchanger for gearbox cooling. The new control panel features fourteen (14) temperature control zones, offering advanced thermal stability and process control. Additionally, all wiring on the extruder is run to a terminal strip for easy installation and connectivity.
This extruder includes two (2) new/rebuilt screws, adding extra value and process flexibility. The drive control is supplied loose, allowing for customized system integration.
Originally built in 1995 and completely reconditioned in 2011, this extruder was never put back into service, making it an excellent choice for those seeking a near-new extrusion system at a used price.
