Quartz Stone Crushing SolutionsLow Energy Consumption Dust Removal Solutions for European Quarry Crushing and Screening Systems That Meet Regulatory Standards
Low-Energy Dust Collection Solutions for European Mines
Quartz Sand Production Line Project Overview
Stationary crushing and screening complete production lines with a capacity of 50–1,200 tons per hour. The entire line is CE certified and complies with the EU Machinery Directive, Low Voltage Directive, and Electromagnetic Compatibility Directive, and is suitable for operating temperatures ranging from -15°C to 40°C. The system serves construction aggregate plants, asphalt mixing plants, precast concrete factories, and railway ballast production lines in countries such as Germany, France, Poland, and Spain, processing medium-hard limestone and certain types of high-hardness rock.
Key Challenges: Excessive dust and noise levels risking heavy fines and production shutdowns; high energy consumption leading to persistently high costs; low automation resulting in heavy reliance on manual labor; and long spare parts procurement cycles causing production delays.
Solution Highlights: Fully enclosed negative-pressure dust collection + electrostatic/baghouse filtration, with emissions below 10 mg/m³ to meet EU BAT standards; low-noise chamber + soundproof enclosure reduces noise by 7–10 dB; intelligent variable-frequency control keeps power consumption per ton of material below 0.35 kWh, saving over 25% in energy; supports OPC UA and Modbus TCP for seamless integration with SCADA; modular design shortens delivery time by 25 days.
Quartz Sand Production Line Process Flow
Heavy-duty vibrating feeder → Jaw crusher (primary crushing) → Cone crusher (secondary and tertiary crushing) → Circular vibrating screen (classification) → Qualified products to stockpile; oversize material returns to the circuit → Optional VSI sand-making machine for shaping + sand washer to produce manufactured sand. Finished products include 0–4 mm manufactured sand, 4–8 mm, 8–16 mm, and 16–32 mm aggregates, compliant with EN 12620 standards. The entire line features variable frequency speed control with automatic adjustment based on material level. Transfer points are equipped with double-layer sealing and negative pressure ventilation, while discharge points utilize spray dust suppression. The feeder has a capacity of 1,500 t/h, the jaw crusher has a feed opening of 1,300 mm, the cone crusher operates at 500–1,200 t/h, the screening area is 18–24 m², and the classification efficiency is no less than 90%.

Quartz Sand Production Line Project Case Studies
Technical Upgrade of a Medium-Sized Limestone Quarry in Bavaria, Germany: Annual production capacity of 1.8 million tons; the original line had received two dust emission violation warnings; power consumption was 0.52 kWh per ton of material; 6 operators per shift. Post-retrofit: Production capacity of 380 t/h reached 95% of design capacity; dust levels at 7 mg/m³—well below the TA Luft limit of 20 mg/m³; noise level at 1 meter from equipment at 82 dB; electricity consumption per ton of material at 0.33 kWh, resulting in annual electricity savings of approximately €68,000; only 2 operators per shift, yielding annual labor savings of approximately €90,000; wear part lifespan increased by 70% to 22 months. Project delivery time: 112 days. Customer Feedback: No environmental complaints have ever been received, and remote monitoring provides a one-week advance warning of liner wear.
Quartz Sand Production Line FAQ
1. How does the production line meet European environmental emission standards?
Fully enclosed negative-pressure dust collection system, with optional bag filters or wet electrostatic precipitators; weather-resistant rubber seals and belt dust covers; CFD airflow simulation optimization at transfer points. Dust levels across the entire line are below 10 mg/m³ and noise levels below 85 dB; third-party test reports are provided. EPC Turnkey Contract for Limestone Aggregate at a European Quarry Verified through multiple European limestone aggregate projects.
2. Does the equipment have CE certification?
The entire line is designed and manufactured in accordance with the Machinery Directive 2006/42/EC, the Low Voltage Directive 2014/35/EU, and the Electromagnetic Compatibility Directive 2014/30/EU. EU Environmental Compliance for Crushing and Screening Production Lines We provide complete CE certificates, EC Declarations of Conformity, and risk assessment documents, and assist with local machinery registration.
3. How can I obtain after-sales spare parts support in Germany or France?
Our Hamburg spare parts warehouse maintains a stock of hammer plates, jaw plates, screen meshes, bearings, and more. Orders placed before 10:00 AM on business days are shipped the same day, with delivery across Europe within 48 hours. Engineers arrive on-site within 48 hours in case of equipment failure, and remote AR-assisted diagnostics are also available. European Crushing and Screening Systems for Construction Aggregates EPC turnkey operation and maintenance services ensure continuous operation.
