Dual-Shaft Shredder for Engine Shredding

The twin-shaft engine aluminium alloy shredder is an industrial machine specifically designed to process scrap aluminium alloy engine castings. Utilising a high-torque, low-speed twin-shaft cutting mechanism, it efficiently shreds large aluminium alloy blocks, providing a front-end processing solution for metal recycling and reprocessing. This equipment is suitable for end-of-life vehicle recycling, aluminium alloy profile recycling and industrial waste processing, and is capable of enhancing metal separation efficiency and resource utilisation.

Equipment Performance and Technical Specifications

This series of twin-shaft shredders comprises four models to accommodate varying production capacity requirements. Specific parameters are as follows: the ZY-SS 800 model has a processing capacity of 1,000–1,500 kg per hour, equipped with a 222 kW twin motor, 18 blades, and a blade diameter of 400 mm; the ZY-SS 1000 model has a capacity of 1,500–2,000 kg per hour, with a motor power of 302 kW, 22 blades; the ZY-SS 1200 model can process 2,000–3,000 kg/h, equipped with a 452 kW motor and 28 blades; the ZY-SS 1500 model has the highest capacity at 2,500–3,500 kg/h, with a dual-motor power of 552 kW and 34 blades. All models feature blades of the same dimensions, Φ400 × 40 mm, whilst the feed hopper dimensions vary by model, ranging from 800 × 1200 mm to 1500 × 2000 mm. These specifications ensure the equipment can reliably crush aluminium alloy blocks of varying sizes and hardness, whilst minimising the risk of entanglement and blockages.

Application Advantages and Operational Insights

The dual-shaft design enables the blades to rotate in opposite directions, achieving uniform crushing through shearing, compression and impact. Compared to traditional high-speed shredders, this equipment’s low-speed, high-torque operation not only reduces energy consumption but also extends blade life. In practice, the ZY-SS 1200 and larger models can operate continuously with stable output, making them suitable for medium to large-scale recycling enterprises. Appropriate model selection should be based on material characteristics and production requirements; for instance, the ZY-SS 1500 is recommended for large volumes of automotive engine blocks to ensure efficiency. The equipment can be integrated with downstream sorting processes such as magnetic separation, air classification and vibrating screens to achieve high-purity aluminium scrap recovery and enhance resource utilisation.
