Pollution Control in Construction: Sustainable Sand and Aggregate Production

The construction industry faces growing pressure to reduce pollution while maintaining efficient sand and aggregate production. Modern crushing and sand-making equipment now integrates advanced dust suppression, noise reduction, and water recycling technologies to minimize environmental impact.

Core Equipment for Eco-Friendly Aggregate Lines

Key components of sustainable production lines include:
– Jaw Crushers: Primary crushing with enclosed design (e.g., 600×900mm feed opening)
– Cone Crushers: Secondary crushing with hydraulic adjustment (e.g., 200tph capacity)
– VSI Sand Makers: Shaping aggregates with low noise (<75dB)
– Airflow Classifiers: Dry process dust control (98% efficiency)

Model Capacity (t/h) Power (kW) Dust Emission (mg/m³)
CJ612 Jaw 300-500 160 <15
HST315 Cone 215-650 315 <20
S10 VSI 100-260 250×2 <10

Frequently Asked Questions

Q: How to control dust in dry processing?
A: Combine sealed conveyors with pulse bag filters and mist spraying systems.

Q: What’s the minimum water requirement for wet processing?
A: Modern systems recycle 90% water; fresh water needs drop to 0.1m³ per ton.

Project Case: Green Aggregate Plant in Norway

A fjord-side operation achieved zero wastewater discharge using:
– Closed-circuit VSI crushers
– Sludge press for sediment recovery
– Solar-powered dust collectors
Production reached 800t/day while meeting strict EU emission standards.
