Limestone Grinding Plant in Saudi Arabia
Limestone desulfurization grinding plant case study in Saudi Arabia. HGM mill producing 250-325 mesh limestone powder for power plant desulfurization. Equipment, process, and performance data.
This case study presents a detailed account of a real-world grinding mill installation project by LIMING, including project background, equipment selection rationale, installation process, commissioning results, and ongoing operational performance. The information is based on actual project data and customer feedback, providing valuable reference for similar projects.
Project Background
A power plant in Jubail, Saudi Arabia, required a limestone grinding facility for flue gas desulfurization (FGD). The specification called for 325 mesh limestone powder at 20 t/h capacity, with a reserve capacity of 25 t/h for peak demand periods.
System Configuration
The FGD limestone system included: primary jaw crusher (PE-600x900), secondary impact crusher, 50-ton storage silo, HGM1680L ultrafine grinding mill, primary cyclone collector, secondary pulse bag filter, and a 100-ton finished powder silo. An automated loadout system filled bulk tanker trucks for delivery to the power plant.
Performance Achieved
Steady-state production of 22 t/h at 90% passing 325 mesh. The HGM1680L's large grinding ring (1680mm) and four-roller design provided the necessary capacity. The integrated pulse bag filter maintained emission levels below 20 mg/m3, meeting Saudi environmental standards.
Operational Highlights
The plant operates 24/7 with 4 operators per shift. Scheduled maintenance is performed every 200 hours for roller inspection and every 2000 hours for bearing lubrication. Grinding ring replacement is projected at 3-year intervals given the soft limestone (3 Mohs). Energy consumption averages 12 kWh per ton.
