• Refurbished exciters meet new‑equipment performance standards
• Customers report longer component life and higher reliability

Pulse Analysis

Vibrating screens are the workhorses of mineral processing, and their exciters generate the precise motion needed for efficient material separation. Because exciters endure continuous dynamic loading, wear on motors, gearboxes and mounting hardware is inevitable, leading to reduced vibration amplitude, uneven feed, and potential safety hazards. Proactive maintenance and timely replacement of these components are therefore critical to sustaining throughput, product quality, and plant stability.

Sandvik's dedicated Exciter Repair and Refurbishment Facility addresses these challenges by applying strict OEM‑level procedures to every unit. Technicians disassemble, inspect, and replace any degraded parts before re‑assembling and testing the exciter to match new‑equipment performance. This in‑house capability eliminates the need for third‑party fixes, shortens lead times, and ensures that refurbished units deliver the same reliability and efficiency as brand‑new components, aligning with Sandvik's lifecycle‑focused service model.

The broader impact on the mining sector is significant. Faster turnaround reduces unplanned downtime, translating into higher plant availability and lower total cost of ownership. Consistent exciter performance also enhances safety by preventing abnormal vibrations that could compromise equipment integrity. As mining operators increasingly prioritize asset longevity and operational resilience, in‑house refurbishment services like Sandvik's set a benchmark for sustainable equipment management across the industry.
