Quartz Powder Grinding Plant in Portugal

Quartz powder grinding plant case in Portugal. HGM ultrafine mill with wear-resistant components producing 325-1250 mesh quartz powder for glass and ceramic. 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 quartz processor in Guarda, Portugal, needed a grinding line for high-purity vein quartz (99.2% SiO2). The target product was 325 mesh quartz powder for glass manufacturing and 1250 mesh for investment casting.

Wear-Resistant Configuration

Quartz at 7 Mohs is extremely abrasive. The HGM100L mill was equipped with ceramic-lined grinding chamber, tungsten carbide rollers, and ceramic classifier blades. The standard chrome alloy components would have worn out within 3 months; the ceramic/carbide configuration extended component life to 18 months.

Performance Results

The mill achieved 4 t/h at 325 mesh and 2 t/h at 1250 mesh. Iron contamination was held below 0.01%, critical for optical glass and semiconductor-grade quartz applications. The wear-resistant configuration increased operating costs by 20% but reduced downtime for component replacement by 80%, resulting in lower total cost per ton.

Project Insights & Lessons Learned

This project demonstrates the importance of proper equipment selection, professional installation, and comprehensive operator training for successful grinding mill operations. Key success factors include thorough material analysis before equipment selection, adherence to installation specifications, regular preventive maintenance, and prompt response to operational issues. LIMING's comprehensive service framework addresses each of these factors, ensuring long-term equipment reliability and customer satisfaction.
