Primary shredder (pre-crusher) PC

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.

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

Pre-shredder Features:

• High stability and quiet.
• Enlarged tooth(knives) for increasing contact surface.
• Hardfacing shaft is resistant to impact and abrasion.
• Discharge stones, sands and small metal parts, minimizing wear and tear costs.
• Auto-reverse system re-orients shredder rotor’s direction when motor overload and material jam.

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.
