The depth of the con- veying channel in the screw is contoured from large to small in the ow direction, to account for the density change from the particulate solid feed to the molten polymer extrudate, and for pressure development. The SSEs normally have diameters between 25 and 250 mm, and length/diameter ratios between 20 and 36.

Screw conveyors and feeders made from engineering polymer provide problem-free handling of materials with abrasive, acid, corrosive, or alkaline properties.
Virtually all twin-screw compounding extruders are starved-fed devices. In a starved twin-screw extruder, the feeders set the throughput rate and the extruder screw speed is independent and used to optimize compounding efficiency. The four high-shear regions are basically independent from the degree of screw fill.

The screw feeder hopper design The hoppers are custom-fabricated in sack-tip, buffer, and loss-in-weight models, and can be equipped with one or several volumetric screw feeders (rigid or flexible). The rotating mechanism ensures a total discharge and an accurate dosing of the powder.
For a single screw, the blend of the polymer/fiber mix into the extruder feed throat must be closely controlled. The old saying is, "Better mix in, better mix out." Although there is localized mixing in single screws, there is little axial redistribution, so if the mix entering is not uniform it …

Twin-screw extrusion (TSE) is the standard for mixing and compounding in polymer processing and has expanded into other applications for new material development. TSE offers a high level of process flexibility, more control of process parameters, and can produce a wider range of products.
The compression ratio is the ratio of the screw depth at the feed zone by the hopper, to its depth at the metering zone by the die. Compression ratio varies greatly according to the polymer that is being processed. For example, where rigid PVC requires a compression ratio of around 2.3:1, polypropylene or a more slippery material requires a ratio of nearer 4:1.
