Product & applications
About the fixed pulverizer
A fixed-jaw hydraulic pulverizer for reducing concrete and separating reinforcing steel during demolition and recycling. Compare jaw opening, blade length and hydraulic requirements for the working material.
Features & benefits
Reversible cutting blades
Rectangular blades cut suitable exposed reinforcing rods and can be reversed or replaced during maintenance.
Cylinder and speed valve
The trunnion-supported cylinder and speed-valve arrangement operate the jaws through their crushing movement.
Typical applications
- Concrete recyclingReduce concrete debris before sorting and recycling.
- Rebar separationBreak concrete away from reinforcing steel.
- Secondary demolitionProcess concrete sections after initial demolition.

Product questions
Fixed 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.
How does it differ from a rotating pulveriser?
A fixed type does not offer powered jaw positioning by rotation. Compare the access and concrete-processing task before choosing the mechanism.
What material is it intended to process?
Its principal task is concrete reduction and reinforcement separation. A steel shear or crusher bucket performs a different task.
