Strategically matching solutions to specific customer needs and applications along with emphasis on the overall improved durability of traditional coal dewatering screens, remains key within the coal processing industry, as it lowers operating costs.

This is according to mining machinery producer Weir Minerals global product manager for screens and screen media Kurt O’Bryan.

He notes that Weir Minerals’ latest developments in coal screen machine technology are focused on increasing the size and mechanical durability of its coal duty vibrating screen line. The company, which has renamed its well-known Linatex range to Enduron, states that the new screens show an increase in throughput and a decrease in downtime.

The Linatex name has been forged within the South African coal industry with sales and installations of Linatex dewatering screens dating back as far as 1983.

“Weir Minerals Africa continues to provide support for these screens and, in a number of installations, the screens have operated for in excess of ten years without any replacement necessary,” notes Weir Minerals Africa product manager for comminution and screens Winchester Maphosa.

Maphosa explains that the Enduron dewatering screen has undergone several design changes to increase the longevity and maintainability of the screens.

“The corrosion-resistant 3CR12 box deck frame design has been replaced with a cross-beam and 3CR12 stringer (runner) design. This has eliminated the downtime and production losses previously associated with premature deck failures owing to latent welding defects,” he says.

The Enduron screen makes use of a 45 feed section which effectively increases the screening area and the dewatering capacities, using high feed-end velocities to aid in the dewatering process.

“All coal dewatering screens in the Weir Minerals range across the globe are backed by the technical expertise of our team, as well as by a pre- and aftermarket support system that ensures improved uptime for coal operations as a result of fast response maintenance and an appropriate parts stockholding,” concludes O’Bryan.
