Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·The demolition of old structures in concrete generates materials which can be recycled in the form of aggregates for new concrete thus preserving natural resources These recycled concrete aggregates are composed of natural elements bounded with hardened hydrated cement paste The fine fraction sands and fillers is however more difficult to reuse
