The environmental recycling and construction waste treatment line focuses on converting construction waste (such as concrete blocks, bricks, asphalt) into renewable aggregates. Through processes such as crushing, screening, and iron removal, efficient separation and resource utilization of waste materials are achieved, producing recycled sand and gravel that meets standards for use in road cushion layers, water stable layers, and non load bearing components. This production line effectively reduces landfill pollution, lowers natural resource consumption, and supports urban renewal and green low-carbon development.
