There are three general steps in the rock and concrete crushing. The first is removing and breaking up material on your jobsite into workable pieces using hydraulic breakers, pulverizers, or other demolition equipment. The second step is removing any metal from the concrete so it doesn’t damage equipment or end up in your aggregate material

Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined.
