<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n<\/figure>\n\n\n\nThe rock breaker had been operating for more than five years and was due for its scheduled refurbishment. Fordjour explains that the work began on site, where Sandvik Rock Processing dismantled the 11 tonne boom assembly using the mine\u2019s cranes. The components were then transported to Sandvik Rock Processing\u2019s Kumasi facilities, a journey of over three hours.<\/p>\n\n\n\n
\u201cOnce in the workshop, our technicians stripped the units completely – checking for critical components such as pins, bushings, cylinder seals and mounting brackets that required replacement,\u201d he says. \u201cThe boom was sandblasted and inspected for cracks, the hydraulic cylinders were rebuilt and pressure-tested and the hammer was fully refurbished.\u201d<\/p>\n\n\n\n
According to Haqq Abdul Rahman, Graduate Technician at Sandvik Rock Processing, maintaining a strong inventory of components and spares is key to speeding up refurbishment projects. He notes that many mines struggle with oversized material arriving at the ROM grizzly and temporary mobile breakers typically take far longer to process these rocks.<\/p>\n\n\n\n \u201cIt was important that we controlled the turnaround time on this project so the mine could put the equipment back to work as soon as possible,\u201d Rahman says. \u201cThis particular unit breaks oversized rocks much faster than the smaller mobile units that the mine had to rely on while this one was being refurbished.\u201d<\/p>\n\n\n\n The Sandvik BB8094R breaker boom, with an input power of 55 kW, offers a maximum reach of 12.7 m, a nominal horizontal reach of 9.8 m, a nominal vertical reach of 9 m and a 360\u00b0 swing. The 2.3 tonne Sandvik BR3288i hydraulic breaker is built on an innovative operating principle that optimises stroke length, blow energy and Sandvik\u2019s idle blow protector. This allows the breaker to be adjusted for different applications while improving hydraulic efficiency and safety.<\/p>\n\n\n\n Fordjour emphasises that quality assurance underpins every stage of the rebuild process at Kumasi.<\/p>\n\n\n\n \u201cWe follow strict operating procedures and standards in everything we do,\u201d he says. \u201cThis includes using only genuine Sandvik parts which allows us to guarantee the quality of both the components and the workmanship.\u201d<\/p>\n\n\n\n After the rebuild was completed, Sandvik Rock Processing returned to site to install and commission the breaker. The three week process required close coordination between Sandvik Rock Processing and the mine to manage crane access, electrical connections, equipment positioning and safety protocols.<\/p>\n\n\n\n \u201cWe work very closely with customers during removal, installation and commissioning,\u201d Fordjour notes. \u201cIn this case, the mine provided the cranes and support equipment and we handled all the technical work; that collaboration is critical.\u201d<\/p>\n\n\n\n Rahman explains that the refurbished boom and hydraulic breaker now deliver several operational benefits. Restored OEM clearances and structural integrity ensure smoother swing and boom movement, more efficient energy transfer and high twist capacity, all of which contribute to improved durability under high-impact conditions.<\/p>\n\n\n\n \u201cFor the mine, the biggest impact is uptime and production,\u201d he says. \u201cWithout this breaker, their crushing circuit slows down considerably; now that it is back to full performance and production is consistent again.\u201d<\/p>\n\n\n\n Fordjour adds that Sandvik Rock Processing\u2019s support continues long after commissioning. The company conducts quarterly inspections to check pins, seals and overall structural condition and the service team remains available for call-outs whenever required.<\/p>\n","protected":false},"excerpt":{"rendered":" At its well-equipped technical workshop in Kumasi, Sandvik Rock Processing recently completed a full refurbishment of critical rock breaking equipment for a major gold mining customer in Ghana.
