Conical vs parallel twin screw barrels: why they are not interchangeable

A conical twin screw changes diameter along its working length, and its matching barrel follows that tapered twin-bore geometry. A parallel twin screw keeps the same nominal diameter through its working section, with two parallel bores at a fixed spacing. Replacing one architecture with the other is......

Segmented vs one-piece twin screw barrels: what can you replace?

A segmented twin screw process section has individual screw elements assembled on shafts and separate barrel housings joined in sequence. A one-piece arrangement uses a continuous screw body, barrel body or both. Segmentation creates smaller replacement units, but it does not make every worn piece s......

Parallel twin screw barrel size codes: identify the machine before you order

The safest way to use a parallel twin screw barrel code is to copy it exactly from the machine nameplate, manual, original drawing or part record. Keep every letter, slash and suffix. Send that code with the extruder maker, full model, serial number, screw and barrel drawings, drive-end details, fla......

Twin screw elements: how function, position and fit work together

Order twin screw elements by machine interface, exact geometry and axial position, not by a broad name such as "kneading block." Preserve both shaft sequences before removal. Record element outer diameter, bore and spline, width, pitch or disc angle, handedness, material, treatment, orientation and ......

PVC Conical Twin Screw Barrel Selection by Formulation

Do not select a PVC conical twin screw barrel from machine size or calcium carbonate content alone. Send the complete formulation with its unit basis, the product and die, target output, actual temperatures and torque, regrind rate, current screw drawing, and measured wear. EJS publishes four CaCO3 ......
