Magnefast – Polymetallic metal mine
A Polymetallic mine in the west of Tasmania produces Zinc, copper and lead concentrates as well as gold.
In September 2023 a trial installation of the Elastotec Magnefast ceramic wear panels was put in place on a dual deck transfer chute. The existing studded white iron wear liners were replaced with Magnefast ceramic wear liners on the top floor and side wall.
The main reasons for making the change to the Magnefast Ceramic Wear Liners were:
- Longer service life from ceramic liners (current wear liner life 6 months)
- Quicker Wear liner changeouts
- Reduced maintenance labour
PERFORMANCE OBJECTIVES:
- Reduce liner changeout time
- Increase service life
- Reduce product usage
- Reduce OH&S risks
- Eliminate scafolding set up
CURRENT CONDITIONS:
Ore type: 25mm Polymetallic (Lead)
Drop height: 500mm onto top floor
Drop height: 1200mm onto bottom floor
Liner changeouts – every 6 months – 3 x 12 hour day shifts.
Scafolding required can take up to 2 hours.
Tonnes per hour: 115
Tonnes over the 6 month period: 517,440
Below photo shows the lower floor white iron worn through into the rubber lining and into the chute substrate.
TRIAL PERFORMANCE:
Magnefast trial achieved 6 MONTHS service life meeting the current liner objective. The Magnefast liners showed 7 mm of wear in a 50 mm thick ceramic, panels have not been replaced and are expected to eliminate several liner changes.
SERVICE LIFE INCREASE (PREDICTED)> 200%
Magnefast liners where not replaced at 6 month planned shut. Some panels rotated saving cost on product and reduced labor.
PROJECTED PERFORMANCE:
Projected Magnefast service life of 18 MONTHS based on a 15mm wear loss where impact occurs at 26-week inspection.
Labor savings by putting Magnefast in is estimated at:
> 80% REDUCTION
