A mobile concrete crusher is a type of heavy machinery used to reduce concrete waste into smaller, reusable aggregate material. This process is essential for recycling concrete and reducing construction waste. Here's how a mobile concrete crusher generally works:
Feeding: The concrete debris is fed into the crusher. This can be done manually or using an excavator or loader that delivers the material into the hopper. The hopper is an initial storage area that holds the concrete debris before it enters the crushing mechanism.
Primary Crushing: The material first goes through a primary crusher, which is typically a jaw crusher or impact crusher in mobile units. A jaw crusher works by using a fixed and movable plate to break up the concrete, while an impact crusher uses hammers or blow bars to throw the concrete against impact plates.
Secondary Crushing (if applicable): Depending on the design of the mobile crusher and the size of the desired final product, the material may go through a secondary crushing stage. This step uses different types of crushers, like cone crushers, which further reduce the size of the aggregates.
Screening and Sorting: After crushing, the material is usually screened to separate fine material from larger aggregates. The screen consists of various-sized mesh screens that can classify the material into different sizes.
Conveyor Belts: Once the material is crushed and sorted, conveyor belts transport it to different piles or storage areas. This process allows for efficient management of the material and easy loading for further transportation or direct use on-site.
Dust Suppression: During the crushing process, dust is typically generated. Mobile crushers may include dust suppression systems, such as water sprays or dust collection systems, to minimize airborne dust levels.
Mobility: Mobile concrete crushers are designed to be portable, with tracks or wheels that allow them to move around a site or between different sites. This mobility is one of the key advantages, permitting on-site crushing without the need for transporting material to a fixed location.
By using a mobile concrete crusher, construction sites reduce the volume of waste material, reuse concrete material effectively, and enhance sustainability by decreasing the need for new aggregate production.
