Weir’s new ENDURON® Elite screen is a large, high capacity, mining-specific machine. It’s a double-deck banana screen, available in a range of sizes with the largest weighing in at close to 50 tonnes and a deck measuring 4.3m x 8.5m.
What differentiates the ENDURON® Elite screen from others on the market?
The ENDURON® Elite screens are driven by Weir’s new ETX exciters, which drive these massive screens with just two exciters. Other machines of comparable size require three exciters.
Notably, this delivers significant advantages in terms of efficiency, lowering energy consumption, as well as simplifying the maintenance requirements.
What screening applications are ENDURON® Elite screens suitable for?
While ENDURON® Elite screens can be utilised in any screening duties in the mill circuit with the exception of primary screening, one specific application they’ve been developed for is to screen Weir’s ENDURON® HPGR discharge.
Weir has been developing a transformational flowsheet in which traditional tumbling mills are replaced by HPGRs and vertical stirred mills, reducing energy consumption by 40%. The ENDURON® Elite screen has a vital role to play in this circuit.
In short, the transformational flowsheet is a closed circuit with the ENDURON® HPGR discharge feeding the ENDURON® Elite screen. The oversize material from both top and bottom decks is recycled back to the HPGR, while the bottom deck undersize product is fed to the vertical stirred mill.
These big banana screens are able to separate material efficiently at small cut sizes, ensuring that Weir can offer a single mill flowsheet, allowing miners to significantly reduce their energy consumption and operating costs, compared to traditional tumbling mills.
Elite screens can also be digitally enabled with NEXT Intelligent Solutions, providing the operator with greater visibility of equipment health and performance, as well as providing the opportunity for process optimisation.
