What Customers Say
Real feedback from operators who upgraded their recycling lines with us.
We moved from inconsistent woven-bag flakes to clean, stable PP output. Moisture dropped below 3%, which made extrusion and pelletizing much more reliable.
Installation and training were smooth. Sand and ink removal from printed sacks is far better than our previous setup, and maintenance has been minimal.
Versatile system that handles both raffia and woven sacks reliably. Our downstream efficiency increased noticeably.
Frequently Asked Questions
Answers to common questions to help you evaluate the best-fit solution.
What PP materials can this line process?
It is designed for PP woven sacks, raffia (tape/yarn), jumbo bags (FIBC), and PP non-woven fabrics. We also handle BOPP-laminated woven bags based on contamination level.
What output and moisture level can I expect?
Typical capacity ranges from 300–1500 kg/h. With the full dewatering + thermal drying configuration, residual moisture typically falls below 3%, suitable for stable extrusion and pelletizing.
Do I need hot washing for printed cement bags or oily contamination?
Hot washing is optional and recommended when you need deeper decontamination (ink, oils, glue, heavy organics). We configure the washing loop based on your feedstock and target end-product.
Can this line produce PP pellets directly?
Yes. Add a squeezer and pelletizing module (such as a water ring pelletizing system) to convert washed PP flakes into uniform pellets. Share your requirements and we’ll recommend the best configuration.
Can you customize the layout and automation level?
Yes. We tailor shredding, washing, drying, and optional pelletizing modules to your capacity, contamination level, and plant footprint, with on-site guidance or remote commissioning available.
