A portable concrete crusher for excavators is a versatile attachment designed to crush concrete debris, bricks, and other demolition waste directly on-site. These crushers are commonly used in construction, demolition, and recycling projects to reduce material volume and facilitate disposal or reuse.
Types of Portable Concrete Crushers for Excavators:
1. Hydraulic Concrete Crushers
– Mounted on the excavator’s arm (typically 3-30 ton excavators).
– Uses hydraulic power to crush concrete with high force.
– Can be fixed or rotating (360° for better positioning).
2. Jaw Crusher Attachments
– Works like a mini jaw crusher, crushing concrete between two plates.
– Ideal for primary crushing of larger chunks.
3. Pulverizer Attachments
– Secondary crushers that break down smaller debris after initial crushing.
– Often used with a primary crusher for finer material processing.
4. Shear-Type Crushers
– Combine cutting and crushing action for reinforced concrete with rebar.
Key Features to Consider:
– Excavator Compatibility – Ensure the crusher matches your excavator’s weight class (e.g., 5-ton, 20-ton, etc.).
– Crushing Force & Jaw Opening – Determines the size of concrete pieces it can process.
– Rotation Ability – Some models offer 360° rotation for better maneuverability.
– Rebar Cutting – Some crushers include built-in shears to cut rebar while crushing.
– Portability & Quick Coupler Compatibility – Allows fast attachment/detachment from the excavator.
