PRODUCT
DESCRIPTION
The Industrial Trommel Screen by Chenxing Recycling Machinery delivers precision size sorting for plastics, metals, and wood with 98% accuracy, engineered for waste management and mining applications. Featuring a fully enclosed drum with adjustable rotation speed (5-25 RPM), this rotary screening system removes dirt, sludge, and sand while ripping open plastic bags via integrated rakes. Customizable screen openings (2-100mm) and unique mesh profiles ensure tailored material classification, paired with zero dust emission for EPA-compliant operations. Its heavy-duty steel frame withstands 24/7 use in recycling plant sorting lines, automatically separating particles onto conveyor belts for downstream processing. Backed by 20+ years of screening expertise, Chenxing’s low-maintenance trommel reduces contamination by 40% versus vibratory screens, with quick-change screen panels enabling <30-minute configuration swaps. Ideal for MSW pre-sorting, aggregate separation, or plastic pellet purification – offering plug-and-play integration and CE-certified safety.

FAQ
1. What is the primary function of a trommel screen in a plastic recycling line?
A trommel screen is mainly used for pre-sorting and separating contaminants from plastic waste before it enters the washing or crushing process. It efficiently removes large debris, stones, sand, metals, and other non-plastic contaminants from materials like plastic films or rigid flakes.
2. What types of plastic materials can be processed with this trommel screen?
The trommel screen is suitable for handling:
-
Post-consumer LDPE and HDPE films
-
Agricultural film waste
-
PP woven bags
-
Mixed rigid plastics
It is often used at the beginning of the recycling line for dirty or unclassified plastic waste streams.
3. How does the trommel screen work?
Plastic waste is fed into the rotating cylindrical drum, which has perforated holes of a specific size. As the drum rotates, undersized material (like sand, soil, or small contaminants) falls through the holes while larger plastic materials exit at the drum’s end for further processing.
4. What are the main benefits of using a trommel screen in recycling?
-
Improves downstream equipment performance by removing harmful debris
-
Reduces machine wear and clogging in crushers and washers
-
Enhances final product purity by ensuring early-stage contamination removal
-
Handles high-volume, heavily contaminated waste with minimal operator input
5. Can the screen aperture be customized?
Yes. The perforation size (typically ranging from 20mm to 80mm) can be customized based on the specific contaminants and material size you want to separate. Drum length and diameter can also be tailored for your throughput requirements.
