USED DAVIS STANDARD 80IN80HT

Description
The Used Davis Standard 9" Extruder, Model 80IN80HT, is a high-capacity extrusion system designed for polymer sheet and film processing. Featuring a 32:1 L/D ratio, this extruder is equipped with a 7-zone electrically heated, water-cooled (closed-loop) vented barrel, ensuring precise temperature control and optimal polymer melt quality.
The gearbox has a 10.15:1 reduction ratio and is rated for 1,080 HP at a 1.5 service factor, providing high torque and efficient performance. It is direct-driven in a wrap-around manner by a 900 HP Reliance Super RPM D/C motor. The unit also features a liquid cooling system with a heat exchanger to protect the gearbox and maintain consistent operation.
For continuous melt filtration, this extruder is equipped with a PSI continuous screen changer mounted on the extruder discharge, along with a 16" x 9.5" feed throat with an integrated magnet for metal contamination control.
Weighing 52,000 lbs. (extruder) and 1,000 lbs. (motor), this unit offers industrial-grade durability and high-output polymer processing capabilities. It was last used for polypropylene (PP) sheet extrusion.

Rare opportunity: Per Davis Standard, the thrust bearing rating is actually 1,468,000 pounds (665,874 kgs) due to a factory mislabeling.

Note: SCR and temperature control panel not included.
