1 . Description:
Conical twin screw and barrel cylinder 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.
Conical 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.
Conical 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.
