Parallel Twin Screw Barrel, 1.38CrMoALA,SACM645, 2.Optimum performance, 3.wearproof/corrosion proof, 4.more lifspan - details see: https://www.machineto.com/battenfeld-parallel-twin-screw-barrel-double-screw-and-barrel-for-extruder-10334572

Our Parallel Twin Screw and Barrel has following features:

• Parallel twin screw and barrel are specially designed forhigh calcium loading.
• compact&reliable gearbox
• designed for high output at low screw speed and less power consumption.
• Two piece barrel construction for economical replacement can be provided.
• Bi-metallic screw&barrel can be provided for two-three times more lifespan than nitrided screw&barrel.

Productsadvantages:

• Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear stress between the small screw
• Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
• Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.
• Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
