Enhancing IsaMill Performance with Strategic Field Support Across the Americas

As the exclusive service delivery partner for Glencore Technology in North and South America, Mechpro has supported IsaMill® installations, maintenance programs, and performance optimization initiatives since 2021. Leveraging deep technical expertise in fine grinding mill systems and field services, this partnership delivers reliable IsaMill support that drives uptime, reduces risk, and enhances operational performance for mineral processing plants across the region.

Challenge

IsaMill is a high-intensity fine grinding technology widely used in base metals, gold, and regrind circuits. While the technology offers superior performance and energy efficiency compared to traditional mills, it also requires specialized field servicing, rapid responsiveness, and precise mechanical execution to maintain reliability in demanding mining environments.

Mines across the Americas needed:

• Specialized mechanical installation and commissioning support
• Rapid diagnostics and corrective maintenance during shutdowns
• Wear component monitoring and management
• Process optimization expertise tailored to IsaMill systems
• Skilled support without the need to augment internal teams

‍

Our Solution

Mechpro and Glencore Technology established a strategic field services partnership to deliver IsaMill support across the complete equipment lifecycle. Our contributions include:

1. Mechanical Installation & Commissioning Support

Mechpro field teams provide on-site mechanical installation and alignment verification during new IsaMill deployments, ensuring all drivetrain, shaft, and bearing systems meet design specifications. Our commissioning support includes system integration checks, operational validation, and pre-start mechanical assessments.

‍

2. Wear Component Management & Predictive Support

IsaMill internal components such as discs, liners, and media experience high wear rates due to intense grinding loads. Mechpro implements disciplined wear monitoring programs, including precision measurements and trend analysis, to help operations plan maintenance and minimize unplanned downtime.

‍

3. Major Overhaul & Rebuild Services

During scheduled shutdowns, Mechpro supports full IsaMill internal overhauls, including component replacement, bearing inspections, and structural verification. Our teams follow predictive indicators to optimize timing for major maintenance events, reducing the risk of catastrophic failures.

‍

4. Process Optimization Assistance

Mechpro works directly with plant metallurgists and process engineers to analyze IsaMill circuit performance. This includes evaluating media sizing, tip speed, density adjustments, and typical operating parameters to improve throughput and grinding efficiency.

‍

5. Rapid Emergency Response

IsaMill failures can severely impact fine grind circuits and overall plant production. Mechpro’s 24/7 emergency field support provides fast diagnostic services and corrective action recommendations, keeping critical plant operations moving.

‍

Measurable Results

Over the course of the partnership, Mechpro has delivered measurable improvements in operational reliability, including:

• Increased IsaMill uptime through proactive maintenance and rapid field intervention
• Reduced emergency failures by rigorous wear tracking and predictive diagnostics
• Lower unplanned downtime rates due to disciplined turnaround support
• Improved operator confidence in the performance of fine grinding circuits
• Optimized throughput in mills supported by process improvement initiatives
