A dedicated exciter repair and refurbishment service at Sandvik Rock Processing’s facility restores vibrating screen components to original equipment manufacturer (OEM) specifications.

Sandvik Rock Processing aftermarket manager for screening solutions: Africa Sydney Baloyi says the facility supports customers throughout the operational life of their screening equipment. Its specialist capability is designed to restore key vibratory components, while reducing downtime and total cost of ownership.

“By repairing and refurbishing customers’ exciters locally, we can give customers rapid turnaround times without compromising our 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 fundamental to the efficient operation of vibrating screens and feeders. Their ability to generate the intended controlled vibration is central to effective material separation 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 continuous dynamic loading.”

Refurbished units undergo the same assembly and testing procedures as new equipment, to ensure consistent performance and reliability once returned to service.

Baloyi says that the emphasis on OEM standards protects customers from premature failures often associated with non-standard repairs.

Beyond productivity, correct and regular maintenance of exciters is also a safety consideration, he adds, as poorly performing vibrating equipment can affect plant stability and process control.
