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 Overview
A calcium carbonate processor in Salalah, Oman, sought to produce premium GCC powder for export to Gulf Cooperation Council countries. The target fineness was 1250-2500 mesh with high 2-micron content (>55%) for high-end paint and coating applications.
Equipment Selection
After material testing at Liming's facility, the LUM1520 vertical roller mill was selected. This model features a 1500mm grinding table diameter, four grinding rollers, and a multi-head classifier system. Auxiliary equipment included a hot air furnace for moisture control, primary jaw crusher, and a coated powder modification system.
Installation Process
The project was completed over 6 weeks. A local contractor handled civil works under Liming's engineering drawings. Two Liming engineers supervised mechanical assembly and electrical installation. The commissioning phase included 72 hours of continuous operation testing.
Results and Client Feedback
The LUM mill consistently produced 6 t/h at 1250 mesh with 58% 2-micron content. Whiteness reached 96%. The integrated modification system produced stearic acid-coated GCC for hydrophobic applications. The client reported 30% higher selling prices for the premium powder compared to their previous 800 mesh product.
Project Insights & Lessons Learned
This project demonstrates the importance of proper equipment selection, professional installation, and comprehensive operator training for successful grinding mill operations.
