Concrete pulverizer
A pulverizer has a fixed and a moving jaw lined with crushing teeth, plus rebar blades near the pivot. It reduces walls, slabs and columns to recyclable rubble while separating steel. Rotating versions align the jaw with the structure without moving the carrier.
Scrap (eagle) shear
A shear has hardened, indexable blades and a piercing tip. It cuts beams, rails, pipes, tanks and car bodies. It is the standard tool in scrap yards and for steel structure demolition.
Multi-processor
A multi-processor uses one body with interchangeable jaw sets – crusher, shear or combi. It suits contractors facing mixed structures who want one investment on one carrier.
Quick comparison
| Pulverizer | Scrap shear | Multi-processor | |
|---|---|---|---|
| Main material | Reinforced concrete | Steel | Both |
| Typical carrier | 14–30 t | 20–40 t | 1–40 t |
| Wear parts | Teeth, blades | Blades, tip | Jaws, blades |
How to choose
Start from the dominant material. If more than 70% of your work is concrete, choose a pulverizer; if steel dominates, choose a shear. If the mix varies job to job, a multi-processor reduces fleet cost. Check hydraulic flow and the number of circuits (jaw + rotation) on your carrier.
