Against the background of strict environmental protection standards and intelligent production requirements in European countries, SMP successfully delivered a 500TPH limestone EPC turnkey project in Greece, providing a full set of solutions from project design, equipment supply, on-site installation to commissioning and operation training. This project is located in Athens, Greece, mainly producing 0-5mm machine-made sand and 5-31.5mm aggregate, which is used for local highway construction and commercial concrete production, and has become a benchmark project for European green and intelligent aggregate production.
### Project Overview
Project Location: Athens, Greece
Processing Material: Limestone (CaO content ≥51%, SiO2 content low, low mud content, no need for mud removal treatment)
Production Capacity: 500TPH (annual output 3000000 tons)
Finished Products: 0-5mm machine-made sand (fine sand), 5-10mm fine aggregate, 10-20mm medium aggregate, 20-31.5mm coarse aggregate
Core Equipment: 2 sets of C6X jaw crushers, 4 sets of large impact crushers, 7 sets of vibrating screens, 1 set of VUS aggregate optimization system, 26 sets of pulse dust collectors
Service Scope: Full EPC general contracting (scheme design, civil engineering design, equipment manufacturing, installation and commissioning, worker training, after-sales maintenance for 1 year)
### Core Process Design & Technical Innovations
The project adopts the "two-stage crushing + two-stage screening + aggregate optimization" process, which solves the problems of high energy consumption, poor product quality and serious pollution of traditional limestone production lines, and realizes the integration of efficiency, environmental protection and intelligence:
1. Primary Crushing Stage: 2 sets of SMP C6X jaw crushers are used for coarse crushing, with a maximum feeding size of 500mm. The optimized eccentric shaft design increases the crushing efficiency by 15% compared with traditional jaw crushers, and the wear-resistant liner extends the service life by 30%, ensuring continuous and stable operation of the whole line.
2. Secondary Crushing Stage: 4 sets of SMP large impact crushers are used for medium and fine crushing. The unique impact plate design realizes the shaping of materials while crushing, making the finished product particle shape uniform and the needle flake content <5%, which fully meets the European aggregate quality standards (EN 12620).
3. Screening & Aggregate Optimization Stage: 7 sets of high-efficiency vibrating screens are used for multi-stage screening to separate 4 types of finished products. The VUS aggregate optimization system is equipped to convert stone powder into high-quality machine-made sand with mud content <3%, which increases the added value of products by 20% and the resource utilization rate to 95% (compared with 70% of traditional lines).
4. Intelligent Control System: The whole line is equipped with an intelligent DCS industrial control system, which realizes one-key start and stop, real-time monitoring of 200+ operation parameters (equipment temperature, load, energy consumption), and automatic generation of maintenance plans, reducing the shutdown rate by 40% and saving 200,000 euros in annual loss.
### Environmental Protection Technology & Compliance
In line with the strict environmental protection standards of the European Union (dust emission ≤10mg/m³, noise ≤75dB), the project has adopted a number of environmental protection technologies to achieve green production:
1. Dust Control: 26 sets of pulse dust collectors are installed at all dust-generating points (feeding, crushing, screening), and the whole production line is equipped with a fully enclosed workshop to ensure that the dust emission concentration is ≤8mg/m³, which is far lower than the EU standard (30mg/m³), and the environmental complaint rate is zero.
2. Noise Reduction: The equipment is equipped with noise reduction covers, and the workshop is laid with sound insulation materials to reduce the noise to ≤70dB, meeting the environmental noise standards of residential and industrial areas.
3. Water Recycling: 3 sedimentation tanks are built to realize 100% recycling of production water, saving 300,000 tons of water annually and achieving "near-zero discharge" of wastewater.
### Project Operation Results
Since its commissioning in 2025, the project has achieved remarkable economic and environmental benefits:
1. Economic Benefits: The annual output value reaches 20 million euros, the resource utilization rate increases by 25%, and the additional output value is 5 million euros; the EPC mode shortens the construction period by 3 months, saving 300,000 euros in construction costs.
2. Environmental Benefits: It has passed the EU green mine certification, the dust emission and noise pollution have been effectively controlled, and it has become a model project for green aggregate production in Greece.
3. Operational Stability: The average daily operation time is 20 hours, the equipment failure rate is ≤2%, and the after-sales team of SMP provides 24-hour technical support, ensuring the continuous and stable operation of the production line.
