Rock Processing team then assembled the Sandvik CH865i on site using the delivered components - including the sub-frame assembly, top shell, bottom shell and main shaft assembly - all in line with our strict OEM standards.” “Following successful commissioning, the increase in output delivered a rapid return on investment for the customer confirming that the decision was the correct one,” says Okunola. To further support ongoing performance, the mine also entered into a service level agreement with Sandvik Rock Processing, ensuring that a dedicated engineer is based on site to maintain and optimise equipment efficiency. “Our team is on hand to closely monitor the condition and operation of our crushers, and to ensure that maintenance such as liner replacement and lubrication are regularly performed,” he says. “Our OEM procedures and attention to detail give the customer peace of mind that the new crusher is delivering as expected, with no unplanned downtime to disrupt production.”

Among the benefits that the Sandvik CH865i cone crusher brings is its ease of operation and maintenance, he adds. For instance, it does not need the application of casting compound when replacing liners which also represents a significant cost saving. Equipped with the hydraulic Hydroset™ system for safety and setting-adjustment functions, the unit is also intelligent - ready to be connected to Sandvik’s Automation & Connectivity System (ACS). This automatically adapts the crusher to varying feed conditions ensuring the best performance constantly. “The value of ACS lies in its ability to monitor key
temperature,” says Okunola. “It also tracks the performance of individual components such as the lubrication pump and the Hydroset™ pump as well as rotation speeds and feed rates. All
“The value of ACS lies in its ability to monitor key aspects of the crushing process including the electric motor’s power draw, hydrostatic pressure, closed-side setting and oil temperature,”
of this enhances operational transparency by flagging any deviations from normal performance.” He highlights that, after the
commissioning of the new Sandvik CH865i unit, Sandvik Rock Processing conducted on-site training for the mine’s team, on both operation and maintenance. “Our training also emphasises the safety aspects of working with our equipment, as our strong safety focus supports the mining sector’s drive towards zero harm,” Okunola concludes. n
