Date: July 12, 2026
Location: Wenchang, Hainan, China
Project Type: Landfill Reclamation & Aged Waste Resource Recovery
Core Equipment: Integrated Heavy-Duty Feeding Hopper, Multi-Shaft Dynamic Screening Matrix, and High-Yield Conveyor Grid Systems
1. Project Background & Site Profile
As coastal land resources become increasingly precious, municipal authorities and environmental asset managers are rapidly turning to landfill mining to reclaim valuable land and eliminate long-term ecological liabilities.
On July 12, 2026, commissioning engineers verified the continuous, high-tonnage operational performance of our latest custom-engineered Aged Waste Sorting Plant deployed in Wenchang, Hainan. Tropical landfill sites present a notorious engineering bottleneck: decades of subterranean compaction combined with high regional humidity cause the excavated waste to become highly sticky, volatile, and tangled with dense, moisture-laden humus soil and degraded plastics.
Standard trommel screens frequently suffer from material blinding and wrapping under these conditions. To overcome this, the Wenchang project site utilizes a specialized, heavy-duty mechanical separation grid designed by Guoxin Group.
2. Technical Infrastructure & Sorting Flow on Site
The raw, excavated municipal aged waste is processed through a highly synchronized mechanical sequence, visible in our active site operations:
- Bulk Mechanical Intake:
A heavy-duty hydraulic excavator continuously feeds the raw, unsegregated aged waste into an oversized, high-torque industrial receiving hopper. The hopper is engineered with reinforced structural anti-bridging walls to handle massive, non-uniform bulk impacts without choking.
- Multi-Shaft Dynamic Screening Deck:
From the hopper, the material flows directly onto our advanced, multi-axis roller/star screening matrix. Driven by a series of high-efficiency synchronized green gearboxes, the multi-shaft design creates a continuous undulating wave movement. This aggressively agitates the sticky waste, shearing the heavy humus soil away from tangled plastic films and textiles.
-
Anti-Clogging & High-Purity Output:
Unlike conventional screens, this dynamic deck completely prevents long-chain polymers from wrapping around the shafts, maintaining a continuous cleaning action.
-
Humus Soil Extraction:
The separated fine fraction—nutrient-rich, stable humus soil—is dropped onto an elevated, high-velocity discharge conveyor belt, continuously forming clean stockpile matrices ready for urban greening or sanitary backfilling.
3. On-Site Operational Performance Metrics
The Wenchang plant demonstrates exceptional field stability, achieving several key processing benchmarks under open-air tropical conditions:
- Continuous Material Flow:
Zero mechanical bridging at the intake hopper, allowing the excavator to maintain a rapid, unrestricted cycle time.
-
High Separation Efficiency:
Achieving an exceptional purity rate in separating organic humus soil (< 30 mm fines) from high-calorific combustibles in a single pass.
-
Robust Structural Design:
Outfitted with industrial-grade, heavy-duty bearings and weather-resistant external drive guards (color-coded for on-site maintenance safety), guaranteeing high uptime despite high ambient salt and moisture air profiles.
4. Engineering Blueprints & Custom Technical Layouts
Every landfill mining footprint features a unique mass-balance matrix based on waste age, moisture profile, and local soil composition. Achieving maximum land reclamation volume requires custom equipment matching rather than generic off-the-shelf hardware.
