Product & applications
About the rotating pulverizer
A rotating hydraulic pulverizer for positioning the jaws around concrete sections, crushing concrete and separating reinforcing steel. Rotation allows the operator to adjust the jaw angle to the work.
Features & benefits
Concrete crushing and rebar cutting
Crushing teeth and a cutting section process concrete and suitable exposed reinforcing steel in the same attachment.
Replaceable teeth and blades
Worn tooth and blade components can be replaced individually rather than replacing the complete jaw.
Typical applications
- Initial concrete demolitionPosition the rotating jaws around accessible concrete sections during initial dismantling, within the excavator reach and lifting limits.
- Concrete recyclingReduce concrete sections and separate exposed reinforcement before sorting and recycling.
- Reinforcement separationUse the integrated cutting section for suitable exposed reinforcing bars; it is not a general-purpose scrap-steel shear.

Force values use tonne-force (tf). The specifications do not state the measurement point; these values are not directly comparable with forces measured at a different jaw position.

Product questions
Rotating pulverizer questions
Are cutting, pulverising and crushing the same task?
No. Identify the material and the intended process first. Steel cutting, concrete processing and bucket crushing use different working mechanisms.
What material and hydraulic information should I send?
Include material type and dimensions, the machine model and available hydraulic supply. Confirm opening, closing and rotation requirements where applicable.
What does rotation change?
It changes the jaw orientation for positioning around the concrete section. Jaw opening, cutting geometry and carrier limits still need checking.
Are rotation and jaw operation the same circuit?
They are separate functions. Confirm the required flow, pressure, connections and controls for the selected configuration.
