    A pre-shredder (pre-crusher) is suitable for the early shredding and working as a debaler of particularly bulky or voluminous materials in bales. One typical example would be disintegrating plastic film in bundles at the beginning of a recycling line. The benefits of preshredder includes wear-off reduction to the proceeding machines and relieving the workload.

    Pre-shredder Applications

    A mixture of domestic and industrial waste
    Mattresses and textiles
    Pressed bales of scrap
    Plastic waste and plastic rolls or in bales (e.g. PET bottles, PP bags, plastic films and compressed plastics)
    End-of-life car and truck tires

    Debaler Introduction

    Pre-shredder is composed of a large diameter rotor, large size tooth and high torque motor.
    Other than featuring rotor and tooth, the low-speed rotor is mainly suitable for handling bulky and non-homogeneous materials such as agricultural films, woven bags and textiles in rolls or bales.

    This debaler is allowed to handle contaminated materials with a high percentage of metal parts or sands. However, the size of the output materials is about palm size. Thus, pre-crusher is generally used as a debaler, a preliminary size reduction or primary treatment.
