The gravity screen piping was wearing out within weeks (picture right). Their stopgap solution was to clamp the rubber liner to the base of the hose to keep it going between shutdowns.
The superintendent wanted something more durable for the high-wear area, so asked our team to come up with a better option.
Gravity screens are notoriously high wear areas. In this case, freefalling slurry was hitting the bends and bottom of the pipework, destroying the hose.
We recommended they use a ceramic lined mining hose. Ceramic tiles are highly resistant to sharp, abrasive slurry, while the flexible hose absorbs and dissipates particle impact.
We worked with him to design the 5-metre DN250 Slurryflex CLX mining hoses, then built them in our Brisbane factory. We delivered them to site in Burkina Faso on time for the shutdown.
We’re confident they’ll last at least three times longer, significantly reducing maintenance costs and lost production time.
