Trommel for plastic recycling

The trommel screen serves as the primary physical separation unit at the front end. Through the tumbling and screening of materials inside the rotating drum, it efficiently removes large foreign particles and fine sand or soil, acting as the first “filtering barrier” to ensure the entire line’s capacity and product quality.

Without a trommel screen, valuable equipment such as crushers and friction washers suffer severe wear. This increases the impurity load, disrupts the stability of rinsing and water treatment systems, lowers the purity of the final product, and raises energy consumption and maintenance costs.

    Low-Speed Rotation, Stable Operation

    Prevents PET bottle damage and avoids secondary contamination.

    Consistent Separation Performance

    Automatically settles and screens out large impurities such as stones, metal, and glass, improving the efficiency of downstream rinsing and crushing processes.

    Dual Collection Design

    Independent front and rear collection systems for easy maintenance and cleaning; supports both wet and dry screening conditions.

    Anti-Jamming Design

    Equipped with internal baffles and self-cleaning devices to prevent material entanglement and enhance operational efficiency.

    Extended Equipment Lifespan

    The trommel drum reduces wear on subsequent crushers and friction washers, lowering maintenance frequency.

     

    Trommel for plastic recycling Process

     

    The trommel screen consists of a large cylindrical mesh tunnel with a sloped rotating drum channel equipped with internal flipping baffles. Material enters at one end of the drum and is continuously tumbled during rotation.

    Large impurities such as stones, metal, and glass are separated during tumbling and slide down to the bottom for centralized collection.

    PET bottles, flexible packaging, and other materials continue to move forward with the rotation, entering subsequent conveying or washing modules.

    Both ends of the drum feature spiral guiding systems and graded discharge outlets, allowing flexible customization of mesh sizes and discharge paths based on material characteristics.

    The drum body is made of stainless steel or manganese steel mesh, offering corrosion resistance, wear resistance, and long-term stable operation.
     

     

    Do You Need to Install a Trommel Screen? (Guidance and Recommendations)

    Scenario Recommendation Explanation
    PET bottle bricks (mixed with various contaminants) Strongly Recommended High levels of contamination require upfront removal to protect downstream equipment.
    Unpacked, well-screened loose bottle flakes Optional Can be skipped if contamination is minimal, saving space and investment costs.
    Agricultural films, woven bags, and other non-bottle materials Optional Recommended if specific contaminants need removal; if contaminants are mostly floatable materials, a trommel screen can be used for pre-separation.
