‌GUIKUANG’s 300,000-Ton High-Purity Hydrated Lime Production Line: Benchmark Case Study‌

GUIKUANG’s 300,000-Ton year hydrated lime (Ca(OH)₂) production line exemplifies cutting-edge industrial innovation with integrated sustainability. This flagship project, operational since March 2024, combines ‌dual raw material compatibility‌ (limestone and carbide slag) with ‌intelligent process control‌ to deliver ultra-fine, high-purity products for global markets.

‌Core Technological Advantages‌

‌Adaptive Pre-Digestion System‌: Dynamic water-lime ratio adjustment via algorithms achieves 98.5% calcium utilization, reducing raw material waste by 22%.
‌Ultra-Fine Grinding & Classification‌: Proprietary air classifiers enable D97 particle size control (3-40μm) and adjustable specific surface area (20-45 m²/g), meeting pharmaceutical-grade purity (＞99.2%) and heavy metal content (＜10ppm).
‌DCS Automation Platform‌: Centralized PLC control ensures 95% uptime through real-time fault prediction (＜0.5% downtime) and automated parameter optimization.
‌Eco-Efficiency Breakthroughs‌

‌Zero-Waste Emission‌: Three-stage dust control (cyclonic separation + pulse bag filtration + wet ESP) limits particulate emissions to ＜5mg/m³, surpassing EU industrial standards.
‌Energy Recovery‌: Waste heat recycling reduces thermal energy consumption by 35%, coupled with variable-frequency drives cutting power use to 28kWh/ton.
‌Economic Performance‌
Deployed at a leading Asian environmental materials conglomerate, this production line achieves:

‌Cost Savings‌: 40% lower OPEX vs traditional vertical kilns through carbide slag utilization and automated labor reduction.
‌Premium Pricing‌: Products command 25-30% price premiums in lithium battery cathode materials and flue gas desulfurization markets.
‌ROI Acceleration‌: Full CAPEX recovery within 2.3 years via 30% export growth to EU/NA markets.
‌Industry Recognition‌
Validated by ISO 9001/14001 certifications, this line sets global benchmarks for high-volume, low-carbon hydrated lime production, driving adoption across 12 countries in cement, waste treatment, and renewable energy sectors.
