Frequently Asked Questions
Twin screws are used for processes requiring conveying, melting, mixing, dispersing, compounding, or other intensive material processing.
The interaction between two screws can provide strong conveying and mixing capabilities, making twin screw systems suitable for many compounding and additive-dispersion applications.
Screw elements should be selected according to polymer type, filler or additive content, required mixing intensity, residence time, throughput, and processing temperature.
ROOTIER can supply twin conical or twin parallel screws base on your machine model.
