A rebuilt exciter is ready for dispatch from Sandvik Rock Processing to the customer following final inspection and approval.
IN-HOUSE EXCITER REPAIR EXTENDS SANDVIK SCREEN LIFE A ccording to Sydney Baloyi, Aftermarket Manager for Keeping screens productive and reliable is vital to mineral processing. To support this, Sandvik Rock Processing operates a dedicated Exciter Repair and Refurbishment Facility that ensures the highest standards are applied to maximise screen uptime and performance.
Screening Solutions (Africa) at Sandvik Rock Processing, the facility plays a strategic role in supporting customers throughout the operational life of their screening equipment. Its specialist capability is designed to restore key vibratory components to OEM specifications, while reducing downtime and total cost of ownership. “By repairing and refur- bishing customers’ exciters locally, we can give customers rapid turnaround times with- out compromising our original equipment manufacturer (OEM) standards,” Baloyi says. “This aligns directly with our lifecycle focus on extending equipment life, improving reliability and reducing ownership costs.” He highlights that the condition of the exciters – including exciter motors and gearboxes – is funda- mental to the efficient operation
equipment to original speci- fications rather than applying temporary fixes,” he emphasises. “Any worn or damaged compo- nents are replaced so the unit is returned to its original condition and performance standard.” Refurbished units then undergo the same assembly and testing procedures as new equipment, ensuring consistent performance and reliability once returned to service. “Meeting the same perfor- mance expectations as new equipment means that refur- bished exciters can fully support customers’ needs for operational continuity,” Baloyi says. This emphasis on OEM stan- dards protects customers from premature failures often
of vibrating screens and feed- ers. Their ability to generate the intended controlled vibration is central to effective material sep- aration and throughput efficiency. “Exciters are essentially the driving force of the screen; without that vibration, the screen simply cannot perform its function,” Baloyi explains. “At the same time, exciters experience significant wear due to continu- ous dynamic loading.” The refurbishment process begins with comprehensive stripping and inspection of the exciters and associated vibra- tory components, including motors, gearboxes and related assemblies. “Our repairs follow strict OEM processes, designed to restore
