Bradken Duaplate DX Plate for Vibe Feeder
Bradken reverse engineered the OEM liner package and revised the liner material to utilise our new high performance Duaplate DX weld overlay material.
Pilbara Region, WA, Australia
A customer in the Pilbara Region of Western Australia, was
operating four Vibrating Pan Feeders processing secondary
crushed iron ore. These vibrating feeders were lined in 500BHN
Abrasion Resistant Steel Plates as specified by the Original
Equipment Manufacturer (OEM). The OEM liner package had
large gaps in the direction of material flow, which resulted in
extreme washout limiting the operational life of the liners to
13 weeks. These liners also weighed more then 70kg and did
not incorporate any lifting solutions, creating safety issues during
install and removal on-site.
The customer preferred a solution that would provide 48 weeks of
operational life between liner change-outs and address the safety
concerns with installation and removal. As Vibrating Pan Feeders
are a fatigue application, it was also important that any solution
did not increase the cyclic loads on the feeder, meaning that any
solution could not increase the total liner package mass.
Bradken reverse engineered the OEM liner package and revised
the liner material to utilise our new high performance Duaplate DX
weld overlay material. The new liner package was supplied with
the same total thickness as the OEM liner package to maintain
the same overall liner mass. The new design consolidated the
liners along each row into a single liner to eliminate the washout
problem by removing the gaps between the liners. The new liners
also incorporated reusable lifting points that allowed the liners to
be installed and removed safely using an overhead crane.
The customer trailed the new Duaplate DX
8/8 liner package
in one of the feeders and after 13weeks, the solution was
performing so well, the customer committed to changing all four
feeders to the new Bradken liner package. After completing
their operational campaigns, the Duaplate DX
8/8 liners met
the customer’s expectation of 48 weeks of operational life. This
allowed the liner package to be changed during the scheduled
workshop refurbishment cycle of the Vibrating Feeders,
completely eliminating liner change-outs insitu onsite.
