Trommel Screen | PET Recycling Pre-Cleaning Rotary Drum Screen
Product Overview
Our industrial trommel screen (rotary drum screen) is a professional pre-cleaning and sorting equipment specially designed for PET bottle recycling lines. It serves as the core front-end processing machine of the recycling system, focusing on preliminary impurity removal and material classification. This equipment efficiently screens out mixed sand, glass debris, loose label scraps and tiny hard foreign matters in waste plastic bottles, thoroughly solving the problem of impurity abrasion and blockage of subsequent processing equipment.
Different from ordinary screening equipment, this trommel screen is equipped with an independent bottom rinsing tank, realizing targeted pre-cleaning of separated bottle caps. It effectively reduces residual dirt and impurities on bottle caps, fundamentally improving the overall purity of finished recycled PET flakes. Meanwhile, the uniform and dispersed feeding design ensures stable material conveying, avoiding material accumulation and intermittent shutdowns, and continuously optimizing the overall operating efficiency of the entire recycling plant.

FAQ | Frequently Asked Questions
1. What impurities can this trommel screen remove?
This dedicated PET recycling trommel screen efficiently removes common impurities in waste bottles, including sand, dust, glass debris and loose label scraps. It separately screens out bottle caps for pre-cleaning, effectively reducing impurity load for downstream recycling equipment.
2. Why do I need a trommel screen for PET recycling line?
Sand, glass and other hard impurities will scratch and wear the blades and screen mesh of downstream washers and dewatering machines, causing frequent part replacement and high maintenance costs. This trommel screen removes hard impurities in advance, protects core equipment, stabilizes production and cuts long-term operation costs.
3. What is the function of the bottom rinsing tank?
The built-in bottom rinsing tank is specially designed for pre-washing separated bottle caps and fine residual impurities. It removes surface dust and residual glue, prevents secondary impurity mixing, and greatly improves the purity of finished recycled PET flakes.
4. Can this trommel screen adapt to my existing recycling line?
Yes. This trommel screen features strong compatibility and flexible installation. It can perfectly match all standard PET recycling equipment without complicated line modifications, suitable for small, medium and large recycling plants.
5. Does the uniform feeding design bring actual production advantages?
Definitely. The uniform dispersed feeding design avoids material accumulation, blockage and uneven feeding issues. It supports stable 24-hour continuous operation, eliminates production fluctuations, and effectively improves the overall output of the recycling line.
6. Is the trommel screen easy to maintain?
This trommel screen adopts a simplified, durable drum structure with few vulnerable parts and a low failure rate. It requires only simple daily cleaning and inspection, greatly saving maintenance time and labor costs.
