screws, barrels and other spare parts
for twin screw extruders (counter-rotating and co-rotating)
Twin screws are divided in parallel and conical configurations.
Counter-rotating twin screw extruders have two screws that spin in the opposite direction. Also often intermeshing this style of machine is usually found in the profile, PVC or wood composite industry.
These machines typically have a much lower screw rpm and generally have much smaller L/D ratios. The screw direction allows for less shear than a single or co rotating machine.
The two styles of machines within the counter-rotating extruder category known as parallel twin screw extruder and conical twin screw extruder. A parallel twin screw has a consistent barrel diameter through the entire barrel. A conical twin screw extruder has a taper. The feed section is much larger than the end of the barrel. Both counter rotating machines with often have barrel venting. The barrels and screws of these machines are not modular so they may need to be changed for your specific application.
