In the recycling process of waste lead-acid batteries, lead paste is the core material with high recovery value and strict purification requirements. Traditional manual sorting and simple filtration often suffer from incomplete separation, high impurity content, low efficiency, and potential environmental risks, which directly affect the smelting purity and economic benefits of enterprises.
Vibration screening technology for lead paste has become a reliable solution in the pretreatment stage of lead-acid battery recycling. Based on high-frequency vibration and specialized screens, it effectively separates lead paste from plastics, rubber, separators, grid alloys and other impurities after crushing. The underscreen product is high-purity lead paste, while the oversize enters the next stage for further sorting.
Compared with traditional processes, vibration screening has three practical advantages:
- Higher purity: Effectively reduces the impurity rate in lead paste and improves raw material quality.
- Higher efficiency: Supports continuous automated production and greatly reduces labor dependence.
- More environmentally friendly: Closed operation with dust and wastewater control helps meet environmental production standards.
For secondary lead and battery recycling enterprises, stable and pure lead paste means lower smelting loss, higher metal recovery rate, and more compliant production. Vibration screening of lead paste is a mature, practical and cost-effective physical separation technology that truly improves recycling efficiency and reduces overall production costs.
