Reliable sizer operation and low wear result in high machine uptime and productivity at a large bauxite operation in Guinea.
Three TAKRAF X-TREME class sizers supplied to a large bauxite mining operation in Guinea are fully delivering on their promise of exceptional reliability and wear behavior. Commissioned in late 2018, the sizers had, as of end February 2021, crushed more than 27 million tons of bauxite ore and are still operating on their original set of wear parts.
The sizers were supplied as part of an important and much needed production expansion project at the mine. This project, awarded in late 2016 to TAKRAF as an EPC contract, encompassed a comprehensive wagon unloading, crushing and conveying system.
The TAKRAF sizers included within the overall system comprise:
- 1 x 3,600 t/h primary TCS-X 14.35 located in the pit beneath the wagon tippler
- 2 x 1,800 t/h secondary TCS-X 08.30 located in the crushing building
Both the primary and the secondary sizers are from TAKRAF’s X-TREME class sizer range. This range was developed to provide extended reliability and availability through a heavy-duty drivetrain, robust shaft and bearing assemblies, and the use of advanced wear resistant materials.
Ease of maintenance is another advantage of the TAKRAF sizer, with the primary sizer installed on site featuring a bolted tooth system, which will enable easy and quick replacement when sufficient wear has been experienced.
Conor Mitchell, TAKRAF Product Manager – Roll Crushers, had this to say when discussing the longevity and reliability of the installed TAKRAF machines: “The combination of high reliability and long lifetime of wear parts means significantly higher machine uptime and that ends up translating into increased productivity for this bauxite operation. These performance levels reinforce that our X-TREME class sizer line provides maximum reliability and availability in difficult conditions which is something the market has been calling for quite some time.”
