Three TAKRAF X-TREME class sizers supplied to a large bauxite mining operation in Guinea are, the OEM says, fully delivering on their promise of exceptional reliability and wear behaviour.
Commissioned in late 2018, the sizers had, as of the end of February 2021, crushed more than 27 Mt of bauxite ore and were still operating with their original set of wear parts.
The sizers were supplied as part of an important 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 comprised one 3,600 t/h primary TCS-X 14.35 located in the pit beneath the wagon tippler; and two 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 to enable easy and quick replacement when sufficient wear has been experienced, the company says.
Conor Mitchell, TAKRAF Product Manager – Roll Crushers, said: “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.”
