Secondary demolition hydraulic crusher YG series

for concretefor buildingfor controlled demolition

Overview
A hydraulic concrete pulverizer crushes reinforced concrete and separates embedded rebar directly on site. Compared with conventional breakers, it reduces noise and vibration while converting thick slabs into reusable aggregate to improve recycling efficiency.

Benefits & Field Data
Field tests show that a dedicated pulverizer mounted on an excavator can increase material recovery efficiency by over 45%, reduce hauling volume and strip rebar cleanly to improve scrap value.

Field Tips

• When working on thick slabs, engage the edge with the rear jaw teeth first to leverage hydraulic force before biting through.
• Use the throat blade section to slice thick rebar rather than pressing with front tooth tips.
• Grease main rotation bearings and pivot pins regularly to protect cylinder seals from fine dust; inspect tooth wear weekly and perform hard-facing before base steel is worn thin.

Matching Excavator Sizes

• Mini & Micro Excavators (1.5–2.5 t): Small single‑cylinder models (e.g. weight ≈135 kg, opening ≈290 mm) for indoor wall removal and tight spaces.
• Small Excavators (3–5 t): Light pulverizers for light demolition and slab cleanup.
• Medium & Heavy Excavators (20–30 t): Heavy rotating models (e.g. weight ≈2250 kg, crushing force up to several hundred kN) for bridge piers and thick floor slabs.

Applications / Where it delivers ROI

• Urban indoor demolition: quiet slab and wall removal with minimal disturbance.
• Concrete recycling yards: reduce feed size for crushers and increase recovered aggregate value.
• Bridge & infrastructure removal: cut and strip rebar cleanly to accelerate secondary demolition.
• Site preparation & land clearing: pair with stump shears to remove old foundations and roots.
