Trommel Screen — The Core Size Control Node Enabling Efficient Separation
Range： Screening range: 5–100 mm (standard)
Application： End-of-Life Vehicle (ELV) recycling plants - Mixed metal recycling plants - Aluminum recycling plants - Motor recycling plants - Automotive Shredder Residue (ASR) processing plants
The SIMVIC trommel screen is a core unit within the plant’s size classification system, designed for continuous sizing of pre-processed or shredded materials. Its value lies not only in screening, but in establishing a stable and predictable material flow through precise size control.In metal recycling processes, particle size distribution directly affects the efficiency of downstream separation systems. By removing fines and oversized materials, the trommel screen ensures more uniform feed into magnetic, eddy current, and sensor-based separation systems, improving sorting accuracy and recovery purity.
From a system engineering perspective, it serves as a prerequisite module for process optimization. It balances material flow and size distribution, reducing load fluctuations and avoiding inefficiencies caused by improper sizing. Its integration with downstream eddy current separators enables seamless material transfer and enhances overall process coordination.Key parameters such as drum diameter, speed, aperture size, and residence time are engineered based on plant capacity and material characteristics. Combined with a heavy-duty design, the system ensures stable long-term operation of the entire plant.
