Covering an area of nearly 8,000 square meters, this solid waste recycling facility is divided into three highly integrated modular zones: Primary Crushing, Secondary Crushing & Screening, and Finished Product Storage. The routing logic is designed to maximize resource recovery while adhering to strict environmental compliance.
Vibrating feeders supply raw C&D waste evenly into the Jaw Crusher. Undersize material from the feeder grizzly bypasses the jaw and is routed to a dirt-removal screen. The primary crushed discharge passes through a manual sorting platform to extract large non-crushable debris before entering the secondary stage.
A European-style Impact Crusher handles the secondary reduction, specifically chosen for its ability to liberate steel rebar and shape concrete aggregates. The output feeds into S5X Vibrating Screens. Oversize material returns to the impactor, while compliant fractions (0-5mm, 5-10mm, 10-31.5mm) pass through belt scales for continuous yield tracking.
To ensure high-purity recycled aggregates, a Light Material Separator processes the 10-31.5mm fraction to remove entrapped plastics and wood. Pulse dust collectors are systematically deployed across the secondary and screening modules to eliminate fugitive dust emissions.
The production line integrates robust crushing equipment with specialized solid waste separation technology to handle the unpredictable nature of municipal C&D debris.
| Processing Stage | Equipment Name | Model Specification | Unit Configuration | Core Operational Role |
|---|---|---|---|---|
| Primary Crushing | Jaw Crusher | Standard PE Series | 1 Unit | Initial volumetric reduction of massive concrete blocks. |
| Secondary Crushing | European Impact Crusher | PFW Series | 1 Unit | Superior cubical shaping and liberation of embedded steel reinforcement. |
| Precision Screening | Heavy-Duty Vibrating Screen | S5X Series | Multiple Units | Pre-dirt removal and precise grading of final recycled aggregates. |
| Auxiliary System | Light Material Separator & Dust Collector | Custom Integration | 1 Set | Extraction of low-density impurities (wood/plastic) and strict emission control. |
Setting an industry benchmark for municipal solid waste processing through green design and centralized automation.
"The engineering layout provided by Liming is highly scientific, and the equipment maturity is evident. What stands out most is the centralized control system, which allows us to manage lean production and daily maintenance seamlessly with only 3 to 5 operators per shift. Furthermore, the meticulous attention to environmental standards—specifically the fully enclosed structure combined with spray and pulse dust collection—has thoroughly resolved noise and dust pollution issues. It is a highly safe and detail-oriented plant design."
Whether it is hard metallic ore, highly abrasive granite, or ultra-large capacity requirements, Liming Heavy Industry's global backbone engineering team will provide a customized 3D process layout and investment budget estimation within 24 hours.
