Can Old Concrete be Crushed for Recycling? - FTM

2019-11-29 · Jaw Crushers - Most recyclers use a jaw crusher for primary crushing because it can handle large pieces of concrete and residual reinforcement. An excavator loads the concrete into the jaw crusher then it chew the larger chunks of concrete into smaller pieces. It reduces concrete to 60-80 mm which can be usually used as fill.
