【System Overview】 

This system adopts a fully enclosed, fully automatic hydraulic separation process for pre-treatment, specially designed for crushing and sorting waste lead-acid batteries. After more than 10 years of production practice and continuous optimization, multiple significant improvements have been made in material structure and process parameters, with equipment and spare parts service life reaching or exceeding imported equipment standards.

【Working Principle】 Waste lead-acid batteries are fed into the crusher through the loading system. The crushed mixed materials are hydraulically separated based on specific gravity differences through lead paste separation screens, multi-stage hydrodynamic separators, and screw conveyors. Four materials—lead paste, lead grid, polypropylene plastic, and separator paper—are finally separated for classified resource recovery.
