Installation of Extruder Twin-Screw Barrel

The installation of the twin screw extruder barrel is a precision operation that requires ensuring the alignment accuracy and correct assembly sequence of the barrel with the gearbox, screws, and other components. According to the latest public information (as of March 2026), combined with authority and applicability, the installation points are as follows:

Preparation before installation

Power off, hang out and lock: Ensure that the equipment is in a safe state to prevent accidental start-up.

Clean up the site and tools: Prepare lifting equipment, copper gaskets, dial gauges, knife edge rulers, copper pry bars, silicone oil or grease, etc.

Confirm the matching between the screw and the barrel: Twin screws are not interchangeable and should be installed according to the original markings (such as "L" and "R"); The direction of the spline groove is usually 12 points for the left screw and 15 points for the right screw.
