Ways to Recycle and Reuse Concrete

Concrete is recycled by using industrial crushing equipment with jaws and large impactors After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate Additional processes and equipment, such as water flotation, separators, and ....
