A circuit board scrap recycling plant is a specialized facility designed to recover valuable materials from discarded printed circuit boards (PCBs). The recycling process involves several stages, each requiring specific types of equipment. The main equipment used in such a facility is crucial for efficiently extracting valuable metals, reducing environmental impact, and ensuring worker safety. Below, we delve into the key equipment used in a circuit board scrap recycling plant.
Pre-Processing Equipment
Shredders are the initial equipment used to reduce the size of circuit boards. High-capacity, low-speed industrial shredders are designed to break down PCBs into smaller, manageable pieces. This size reduction is essential for subsequent separation processes.
Features: Robust construction, adjustable shredding size, and overload protection.
Benefits: Enhances the efficiency of downstream processes and ensures consistent material feed.
Separation Equipment
Magnetic separators are used to extract ferrous metals (such as iron and steel) from the shredded and granulated material. These separators use powerful magnets to pull ferrous metals away from the non-ferrous fraction.
Features: Drum or belt magnets, adjustable magnetic strength, and continuous operation.
Benefits: Efficient removal of ferrous metals, protecting downstream equipment from damage.
Air classifiers use airflow to separate materials based on their density and size. Lighter, non-metallic materials are carried away by the air stream, 重い金属粒子が別の収集領域に分類されますが.
Features: 調整可能なエアフロー, 複数の分離段階, および統合されたダストコレクションシステム.
Benefits: 微粒子の効率的な分離, 後続の処理装置の負荷を削減します.
静電分離器は電荷を使用して導電性材料を分離します (金属など) 非伝導材料から (プラスチックなど). この技術は、微粒子分離に特に効果的です.
Features: 高電圧静電界, 調整可能な分離パラメーター, および高スループット容量.
Benefits: 混合材料の正確な分離, 回収された金属の純度を高める.
