SA mine opens tertiary screening plant

Rocktec has won a contract with Southern Quarries to provide a tertiary screening plant at its Sellick?s Quarry. Located between Aldinga and Myponga, just outside Adelaide, South Australia, the quarry is mined for dolomite and bluestone.

Southern Quarries undertook a competitive tender process, which included local suppliers, before selecting Rocktec.

Southern Quarries CEO Brett Brown visited Matamata in New Zealand, where Rocktec is based, to personally learn more about the company?s manufacturing operations and capabilities. This evaluation also included Rocktec?s health and safety and quality values. Brett also had the opportunity to see the Stevenson Drury quarry that Rocktec had previously supplied in 2003.

?Viewing first hand the quality of Rocktec?s manufacturing and processes, as well as taking into account their proven track record in delivering plant to a wide range of both local and international customers, helped to swing the decision in their favour,? said Brett Brown.

?It was crucial that we found a company that we could see as a project partner, not just a supplier of screens and conveyors when undertaking our evaluation of suppliers. The positive ?can do? attitude of all of the team at Rocktec gives us a lot of confidence that this will be a very successful project.?

Rocktec CEO Rick Johnson also said he was ?pleased to have won a tender with a company of the calibre of Southern Quarries. They have demonstrated that they are forward thinking and open to new technology. It?s clear they are only interested in working with technology and suppliers with a good track record. This outcome represents a vital step in our strategic penetration of the Australian market and our efforts to provide cost-effective solutions for its quarry industry.

?We?re looking forward to providing Brett and his team with a solution that meets not only today?s needs but offers them the flexibility to meet their future client needs.?

Rocktec?s tertiary screening plant will be connected to the output of a secondary plant that Southern Quarries has purchased and relocated from Malaysia. This plant will crush and screen through primary and secondary stages.

The tertiary plant supplied by Rocktec will take the output from a Barmac 9100 VSI crusher at 400 tonnes per hour and provide multiple screening and stockpiling options (including radial stacking), which will produce the various graded product splits required by Sellick?s Quarry.

The plant will include three new evolution Sandvik SC screens (two SC2463 20? x 8? and one SC1852 16? x 8? units) that will be commissioned with wire screen media sizing at the appropriate apertures. The plant will include 11 conveyors and three radial stacker conveyors. It will be able to produce aggregate ranging from sand to 20 mm aggregates.

Rocktec has commenced the design phase and will complete the project by July 2010. Rocktec will assemble the tertiary screening plant on-site at Sellick?s Quarry.

Although this Southern Quarries project is not Rocktec?s first successful tender win in the region, it is its first quarry plant supply project in South Australia. Rocktec had previously provided significant specialty mining equipment for Project Magnet, a OneSteel mining development at Whyalla, near Adelaide.
