Aggregates for quality concrete from debris using ...

The optimized crusher is a jaw crusher specially designed for concrete recycling. The purpose of the machine is to separate concrete into its constituent sand, gravel and cement paste, based on the principle of Smart Crushing. Ordinary crushers are usually used only for the purpose of reducing particle sizes which will crush all the component materials randomly; in the case of concrete, this will include crushing through the aggregates as well as between them. This optimized type of crusher is intended to separate concrete into the composite materials without the risk of the components themselves being damaged, by adjusting the crushing force to an intermediate one between the average compressive strengths of the aggregates and the one of the hardened cement paste.
