The C12+ is a versatile option for contractors processing mixed construction and demolition debris.
Impact Crushers: Versatile Secondary Processing for C&D Waste
Impact crushers use high-speed impact rather than compression to break down materials, making them ideal for processing concrete that contains rebar and other reinforcing materials. They also produce more cubical-shaped aggregate compared to jaw crushers, which is desirable for many construction applications. Several mobile impact crusher models have been specifically designed for construction waste recycling.
4043T Impact Crusher
The 4043T impact crusher features standard Caterpillar tracks with high-speed travel capability and a 300-horsepower Caterpillar C-9 ACERT Tier III diesel engine. The tracked mobility allows this unit to move easily around demolition sites, positioning itself close to active demolition zones. The high-speed track travel reduces non-productive movement time between positions within the site.
Hybrid Traxx Track-Mounted Impactor Plant
The Hybrid Traxx system employs a diesel-electric power arrangement for both the impactor and the plant functions, with hydraulic operation powering the tracks. This hybrid configuration offers several advantages for waste processing sites:
- Reduced fuel consumption compared to fully diesel-hydraulic systems
- Lower noise levels during operation, beneficial in noise-sensitive urban areas
- Reduced emissions, supporting environmental compliance targets
- Electric power for the crusher provides consistent torque regardless of engine speed
Pegson XH250 Trakpactor
The Pegson XH250 Trakpactor is designed specifically for crushing concrete and asphalt rubble as well as construction and demolition debris and limestone with low to medium hardness. Its smaller footprint and weight make it ideal for projects where access is restricted or where waste volumes do not justify a larger primary crusher. The XH250 can serve both as a primary crusher for smaller demolition jobs and as a secondary unit in larger operations.
QuarryTrax Model TI6060 Primary Impact Crushing Plant
For high-capacity applications, the QuarryTrax Model TI6060 track-mounted primary impact crushing plant is designed to handle production rates up to 800 tons per hour. This machine targets large-scale infrastructure demolition projects where massive volumes of concrete and asphalt must be processed on a tight schedule. The TI6060 combines the mobility of a tracked platform with the throughput of a stationary crushing plant.
Cone Crushers and Vertical Shaft Impactors for Final Aggregate Refinement
After primary and secondary crushing, cone crushers and vertical shaft impactors (VSIs) provide the final stage of material refinement. These machines produce high-quality aggregate that meets specifications for road base, drainage material, and new concrete production. Using these machines on site allows contractors to convert waste into a revenue-generating product rather than a disposal cost.
Sandvik 1080 Track-Mounted Cone Crusher
The 1080 track-mounted cone crusher system features a Sandvik 385-horsepower H3800 crusher developed with the CSC (cubical shape crushing) technique. This technique produces aggregate with excellent particle shape, which is critical for applications such as asphalt production and concrete manufacturing. The tracked platform allows the 1080 to be positioned in the crushing circuit wherever it is needed, directly after the primary jaw or impact crusher.
V-Slam Model VS-88 Vertical Shaft Impactor
The V-Slam Model VS-88 vertical shaft impactor features innovative housing and rotor designs along with an easy-access low-profile split swing lid for maintenance. Key advantages of this VSI design include:
- Superior cubical shape of the final product
