A baseline assessment conducted on site is the foundation for restoring vibrating screens to OEM standards and boosting long-term performance.

CRUSHING AND SCREENING

SANDVIK ROCK PROCESSING’S LIFECYCLE STRATEGY CUTS SCREEN COSTS PER TONNE By embracing a lifecycle management approach with its customers, Sandvik Rock Processing ensures that its vibrating screens meet production targets at the lowest cost per tonne.

T he most effective starting point, says Lifecycle Solutions, is for mines to request a full assessment from their OEM partner. “This allows for a gap analysis to identify opportunities for improvement, so the equipment can be restored to OEM standards in terms of reliability and performance,” explains Sukati. “The customer might also require that operators receive targeted on-the job training, which helps ensure performance is maintained.” Sandvik Rock Processing’s assessments include a visual inspection followed by dynamic Lomave Sukati, Sandvik Rock Processing’s Business Line Manager

part sourcing to be planned well in advance. This prevents unscheduled downtime and allows maintenance work to be done during planned plant shutdowns. The performance of the screens is also affected by the changing nature of the ore bodies being mined, which requires constant monitoring – as changing geology could result in more abrasive material being crushed and screened. “This may call for a different choice of wear materials in the screen panels to achieve the required output and wear life,” she says. “Screens are specified for certain conditions at the start of a project but adjustments invariably need to be made during the

testing to measure mechanical performance. Any defects or concerns are then detailed in a report to the customer for action. “Our training empowers a customer’s team to recognise conditions that need early attention, as part of overall lifecycle management to keep equipment well maintained and productive,” she says. “The OEM can’t always be on site to conduct daily checks but operators can be trained to do this and a close working relationship with the OEM ensures there are open lines of communication to report issues.” Regular inspections allow the remaining wear life of parts and components to be estimated and logged, enabling maintenance and
