15,000 TPY Lime Rotary Kiln Production Line in Yangquan, Shanxi: A Benchmark in Efficient & Eco-Friendly Lime Manufacturing

Yangquan, Shanxi, is renowned for its abundant, high-quality limestone reserves, making it a strategic hub for the lime manufacturing industry. To meet the growing demand for high-purity active lime while adhering to stringent environmental standards, a major industrial project required a reliable and advanced calcination solution. Henan Hongke Machinery was selected to design, manufacture, and commission a state-of-the-art 15,000 TPD (Tons Per Day) lime rotary kiln production line. This successful case study highlights our capability to deliver customized, energy-efficient, and environmentally compliant heavy machinery solutions.

Project Overview: Tailored for High-Performance Calcination

The 15,000 TPD lime rotary kiln production line in Yangquan was engineered to maximize output while minimizing energy consumption and emissions. Henan Hongke Machinery provided a comprehensive EPC (Engineering, Procurement, and Construction) approach, ensuring seamless integration of all critical components.

Key Project Specifications:

• Location: Yangquan, Shanxi Province, China

• Daily Capacity: 15,000 Tons of High-Active Lime

• Raw Material: High-purity limestone from local Shanxi mines

• Core Equipment: Advanced rotary kiln with vertical preheater and vertical cooler

• Fuel System: Multi-channel pulverized coal burner with optimized air-fuel ratio

Core Technological Advantages by Henan Hongke Machinery

To ensure the production line met the rigorous demands of the Shanxi market, Henan Hongke Machinery integrated several proprietary technologies:

1. Advanced Calcination & Preheating Technology

Limestone in the Yangquan region can be prone to thermal shock and cracking during rapid heating. Our production line features an innovative vertical preheater system that utilizes kiln tail exhaust gases for secondary preheating. This two-stage preheating and calcination process prevents limestone爆裂 (bursting), ensuring high structural integrity of the final active lime product and significantly reducing powder generation.

2. Energy Recovery & Eco-Friendly Design

Sustainability is at the core of our engineering. The Yangquan project incorporates a highly efficient waste heat recovery system. High-temperature exhaust gases from the kiln tail are captured and reused for preheating raw materials and generating electricity, drastically reducing the overall carbon footprint and operational fuel costs. Furthermore, the line is equipped with a comprehensive desulfurization, denitrification, and dust removal system, ensuring all emissions strictly comply with national ultra-low emission standards.

3. Intelligent DCS Control System

Precision is key to consistent lime quality. Henan Hongke Machinery deployed a cutting-edge Distributed Control System (DCS) with AI-driven optimization. The system features:

• Real-time monitoring of kiln head/tail temperatures and exhaust CO concentrations.

• Automated adjustment of the multi-channel burner and primary air volume to maintain optimal flame shape and temperature (850°C–950°C).

• Smart alarm systems and strict permission management to ensure safe, stable, and unmanned operation.

Operational Excellence & Client Benefits

Since its successful commissioning, the 15,000 TPD lime rotary kiln production line has delivered exceptional operational metrics, validating Henan Hongke Machinery's engineering expertise:

• Superior Product Quality: The active lime produced consistently achieves a CaO content of ≥85%, with a standard deviation of less than 0.8%, meeting top-tier metallurgical and chemical industry standards.

• Significant Energy Savings: Through optimized combustion and waste heat utilization, the production line has reduced unit coal consumption by over 10%, translating to substantial annual cost savings.

• Enhanced Operational Efficiency: The intelligent DCS system has reduced the required control room personnel by over 60%, shifting from manual intervention to predictive maintenance and smart alerts.

• Environmental Compliance: The integrated emission control systems have achieved ultra-low particulate, SO2, and NOx emissions, securing the plant's status as a green manufacturing benchmark in the region.
