Lime Powder Grinding Plant in Kazakhstan
Quicklime and hydrated lime grinding plant case in Kazakhstan. HGM ultrafine mill producing 200-325 mesh lime powder for construction and metallurgy. Equipment and results.
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 lime producer in Karaganda, Kazakhstan, needed a grinding facility for quicklime (CaO) and hydrated lime (Ca(OH)2). The powder was destined for gold ore processing (cyanidation pH control) and construction (dry-mix mortar). Target fineness was 200-325 mesh.
Equipment and Safety
The HGM80 ultrafine mill was modified for lime processing: sealed grinding chamber with inert gas purging to prevent hydration, water-cooled bearings to manage heat from CaO reaction, and an enhanced dust collection system with 99.9% efficiency. Quicklime is highly reactive with moisture, requiring specialized handling.
Production Results
The plant produced 4 t/h at 325 mesh hydrated lime and 5 t/h at 200 mesh quicklime. The sealed system maintained product quality by preventing atmospheric hydration during grinding. For gold cyanidation, the fine lime powder achieved 95% slurry pH adjustment within 10 minutes, improving gold recovery efficiency.
Project Insights & Lessons Learned
