Frequently Asked Questions

Yes. The line can be configured for mixed rigid plastic feedstock including PP, HDPE, PVC, ABS, and other regrinds. Sizing depends on contamination level, density separation needs, and required output quality.

With centrifugal dewatering followed by thermal drying, final moisture is typically below 3 percent, suitable for storage or downstream pelletizing.

No. The system supports closed-loop water reuse with filtration and settling, which helps reduce make-up water demand and operating cost.

We size the line based on material type, contamination level, throughput target, and available floor space. Sample evaluation can be used to confirm the most suitable layout.
