On-site concrete crushing equipment is used to recycle concrete debris from construction and demolition projects directly at the job site. This process reduces waste, lowers disposal costs, and provides reusable materials like aggregate for new construction. Here are the key types of equipment used for on-site concrete crushing:
1. Primary Crushers
– Jaw Crushers:
– Ideal for breaking large chunks of concrete into smaller pieces.
– Adjustable jaws allow control over output size (typically 3″–6″).
– Examples: Komatsu BR380, Terex Pegson XR400.
– Impact Crushers:
– Best for softer or less dense concrete.
– Produces a more uniform, cubical product.
– Examples: Rubble Master RM100, Metso Lokotrack LT1213.

2. Secondary Crushers
– Cone Crushers:
– Used for finer crushing after primary processing.
– Produces smaller aggregate (½”–2″).
– Horizontal Shaft Impactors (HSI):
– Efficient for high-volume secondary crushing.
3. Screening Equipment
– Vibrating Screens: Separate crushed material by size (e.g., fines, base material).
– Trommel Screens: Useful for sorting mixed debris (concrete, rebar, dirt).
4. Portable vs. Stationary Systems
– Portable Crushers (Tracked or Wheeled):
– Mobile units that can be moved between sites (e.g., Komatsu BR550JG-1).
– Stationary Crushers: Fixed setups for large-scale recycling plants.
5. Attachments for Excavators & Loaders

– Examples: NPK G-Series, LaBounty CP Series.
6. Conveyors & Magnets
– Stacking conveyors transport sorted material efficiently.
– Electromagnetic separators remove rebar and metal contaminants.
Key Benefits of On-Site Crushing:
✔ Reduces landfill waste & disposal costs.
✔ Recycles concrete into usable aggregate (base material, road fill).
✔ Minimizes transportation emissions by processing on-site
