Concrete Recycle Methods

08-12-2005· Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...

Recycled concrete (Source: YouTube/ERC-TECH EU) Methods of Recycling Concrete. The equipment used for crushing the concrete rubble generally consists of a rubble crusher, side discharge conveyor, screening plant and a return conveyor from the screen to the crusher inlet. The return conveyor sends back the oversized materials or the other under crushed materials which needs reprocessing.
