A Concrete Jaw Crusher is a heavy-duty machine specifically designed to break down large chunks of concrete, reinforced concrete, and other construction demolition waste into smaller, usable aggregate. It operates using a powerful compressive force, generated by a fixed jaw and a moving jaw (called a “swing jaw”), which acts like a giant nutcracker to crush the material down to a predetermined size. These crushers are the primary workhorses in recycling operations, turning waste concrete into valuable base material for new construction projects, driveways, or road sub-base, promoting sustainability and reducing landfill costs.
Our concrete jaw crushers are engineered for durability, power, and efficiency in the most demanding environments. Key features include:
Heavy-Duty Structure: Built with high-grade steel and reinforced frames to withstand the immense stress of crushing hard concrete and embedded rebar.
Powerful Crushing Jaws: Equipped with robust, replaceable jaw plates made from high manganese or other advanced alloys for superior wear resistance and long service life.
Hydraulic Adjustment: Allows for quick and easy adjustment of the crusher’s closed side setting (CSS) to control the final output product size without the need for manual shims.
Reinforced Design for Rebar: Specialized designs and crushing chambers efficiently handle and separate embedded steel rebar during the crushing process, minimizing downtime.
Versatility: Can be configured as stationary units or, more commonly, as portable (wheeled or tracked) plants for moving directly to the demolition site, enabling on-site recycling.
Investing in a concrete jaw crusher offers significant operational and financial benefits:
Cost Savings: Dramatically reduces disposal fees by recycling concrete on-site and eliminates the need to purchase new aggregate.
Revenue Generation: Creates a valuable product (recycled concrete aggregate – RCA) that can be sold or reused in new projects.
Environmental Sustainability: Diverts concrete waste from landfills, reduces the need for virgin quarry material, and lowers the carbon footprint associated with transport.
High Efficiency & Productivity: Powerful engines and optimized crushing chambers ensure high tons-per-hour output, making large demolition projects profitable.
Mobility: Portable models (tracked or wheeled) can be easily transported between job sites, providing crushing capabilities exactly where and when they are needed.
Selecting the right crusher is crucial for your project’s success. Consider these factors:
Project Scale & Feed Material: Estimate the total volume of concrete to be crushed and the maximum size of the chunks. Larger, reinforced pieces require a larger, more powerful crusher.
Desired Output Size: Determine the required final product size (e.g., 2-inch base, ¾-inch drainage stone). This will dictate the necessary adjustments and model capabilities.
Mobility Needs: Decide if a stationary plant (for a fixed recycling yard) or a mobile crusher (for moving between multiple demolition sites) is required.
Production Capacity: Match the crusher’s output (tons per hour) to your project timelines to ensure it can meet your deadlines.
Power Source: Choose between diesel (for ultimate mobility and power) or electric (for lower operating costs and emissions in fixed locations).
To ensure safety, maximize productivity, and extend the machine’s lifespan, pay attention to the following:
Pre-Crushing Inspection: Always remove non-crushable materials like wood, plastic, and large pieces of metal from the concrete feed to prevent damage to the crusher.
Mind the Rebar: While designed to handle rebar, extremely large and dense mats of steel can cause problems. Pre-processing with a pulverizer or shear can be beneficial.
Regular Maintenance: Adhere strictly to the manufacturer’s maintenance schedule for greasing bearings, checking jaw plate wear, and monitoring hydraulic systems.
Operator Training: Ensure operators are fully trained on safe startup, shutdown, and operational procedures to prevent accidents and misuse.
Monitor Feed Rate: Avoid overfeeding the crusher, which can lead to jamming, premature wear, and damage to the engine and drive components.
