Global Recycling Success Story
Converting Aggressive Demolition Waste into High-Grade Aggregate
The Project Challenge: Metal Foreign Objects & High Clay Content
An environmental recycling plant specializing in urban renewal projects faced critical bottlenecks when processing raw demolition waste. The incoming material was highly heterogeneous—heavily contaminated with wet soil, clay, and mixed concrete segments containing hidden rebar and tramp iron blocks. Their conventional impact crushers suffered from catastrophic rotor damage caused by iron strikes and experienced severe clogging on rainy days, making steady high-yield operation impossible.

2PGC1000×1200 Hydraulic Double Toothed Roller Crusher
The Engineering Strategy: Custom-Toothed Heavy-Duty Sizing
Our application engineers deployed the 2PGC1000×1200 Hydraulic Double Toothed Roller Crusher, explicitly adapting the roll geometry to handle high-impact urban debris. By utilizing a low-speed, high-torque counter-rotating movement, the crusher effectively gripped and shattered large concrete blocks using a combination of extrusion and shearing force, bypassing reliance on traditional impact grids.
Verified Operational Breakthroughs:
- 100% Tramp Iron Immunity: The integrated automatic hydraulic protection system instantly sensed unbreakable iron spikes, retracted the rolls to let them pass safely, and reset automatically within seconds without halting the production line.
- Zero Sticky Adhesion: The self-cleaning tooth profile completely eliminated material bridging and blind-spot accumulation caused by wet clay-rich soils.
- Superior Cube Output: The concrete aggregate produced featured a dense, strictly cubic shape with low needle-flake content, instantly qualifying it for premium commercial recycling standards.
- 20% Operational Energy Drop: The optimized low-speed crushing dynamic slashed overall system electricity costs by one-fifth compared to traditional high-speed kinetic milling.
Conclusion
By introducing intelligent hydraulic safeguards paired with robust alloy tooth surfaces, the recycling facility successfully transformed a hazardous, high-downtime bottleneck into a safe, automated, and continuous revenue-generating production loop, turning mixed environmental waste into premium commercial-grade aggregates.
