- Model: 3.5" 30:1 L/D Extruder
- Condition: Used
Description:
The Welex 3.5" 30:1 L/D Extruder is a high-performance extrusion system, ideal for plastic processing, compounding, and recycling applications. Featuring an electrically heated, water-cooled (closed-loop) vented barrel, this extruder ensures efficient temperature management and consistent melt quality.
Mounted at an approximate 69" centerline height, this extruder's height can be reduced by 8 inches by removing the additional base, allowing for greater flexibility in plant integration.
The system is powered by a 150 HP Emerson DC motor, which is direct-driven in a tuck-under manner via a Lufkin change gear gearbox with a 13.89:1 reduction ratio. A Control Technique Mentor II SCR drive ensures precise speed and torque control for optimal performance.
For enhanced material processing, the unit includes a Dynisco EH-35 hydraulic screen changer with a 3 HP hydraulic pack, mounted on the extruder discharge, along with a 20 HP melt pump with integrated controls.
The integral control panel features fourteen (14) zones of temperature control, providing advanced process optimization for various extrusion applications.
