Date: March 30, 2026
Location: Hohhot, Inner Mongolia, China
Capacity: 200 Tons Per Hour (approx. 4,000 Tons/Day)
Feedstock: Mixed C&D waste (Concrete, bricks, wood, plastics, and soil)
Project Background & Local Policy
Hohhot has seen rapid urban renewal in recent years, leading to a surge in construction debris. Local environmental regulations now strictly prohibit the landfilling of unprocessed C&D waste, mandating a recovery rate of over 85%. The client required a robust system capable of handling heavy concrete blocks while maintaining high-purity output for recycled bricks and road-base aggregates.
The Challenge: High Dust & Heavy Impact
The Inner Mongolian climate presents unique challenges: extremely dry conditions that generate massive dust during crushing, and a high proportion of reinforced concrete that demands high-torque shredding capabilities.
Process Flow & System Configuration
-
Heavy-Duty Vibrating Feeding: Removes soil and fines ($<30mm$) at the initial stage to reduce wear on downstream crushers.
-
Primary Impact Crushing: High-manganese blow bars break down large concrete slabs into manageable sizes.
-
Magnetic Separation: Over-belt magnets extract 99% of rebar and ferrous scrap, turning it into a direct revenue stream.
-
Air Classification (Light Material Sorter): A high-pressure air blower removes wood, plastic, and foam from the heavy stone stream.
-
Multi-Stage Vibrating Screening: Grades the clean mineral fraction into specific sizes: 0-5mm (sand), 10-20mm (fine aggregate), and 20-40mm (coarse aggregate).
Core Equipment List
| Equipment Unit | Model / Specification | Purpose |
| Primary Crusher | GX-Impact 1315 | Concrete & brick reduction |
| Magnetic Separator | RCYD-12 | Rebar and steel recovery |
| Light Material Air Sorter | GX-Air 1500 | Removing wood and plastics |
| Dust Suppression System | Integrated High-Pressure Mist | Environmental compliance |
Project Performance Data
-
Recovery Rate: 92% of input material is diverted from landfills.
-
Daily Output: Approx. 3,500 tons of recycled aggregate and 15 tons of scrap metal.
-
Purity: Recycled stone contains less than 0.5% organic impurities, meeting local road-base standards.
Cost-Benefit & ROI Analysis
-
Tipping Fee Revenue: By accepting local C&D waste, the plant earns a fixed processing fee per ton.
-
Product Sales: Recycled aggregates are sold to local brick factories and road construction projects at 60-70% the price of virgin stone.
-
ROI Cycle: Based on the current 200 TPH throughput and local stone prices, the estimated payback period is 14-18 months.
Field Feedback
“The Guoxin system handles our heavy concrete loads without the frequent downtime we experienced with our previous setup. The air sorter is particularly effective—the stone comes out clean enough for immediate use in road-base without secondary washing.” — Project Manager, Hohhot Site.
