SCREENING
deployment of its SuperStack , StackSizer and other screening technologies for both haematite and magnetite iron ore classification .
As an example , the Derrick Australia team worked closely with partners to deliver no less than 88 Derrick Fine Screens to the Iron Bridge Magnetite Project in Western Australia which is a JV between Fortescue ’ s FMG Magnetite Pty Ltd ( 69 %) and Formosa Steel IB Pty Ltd ( 31 %). One of Australia ’ s most considerable magnetite resources , Iron Bridge sought to enhance the production of DR-grade iron ore concentrates .
The Derrick screens play a crucial role in the Iron Bridge wet plant following both the secondary STM HIG mill regrind step prior to cleaner magnetic separation ; and following recleaner magnetic separation after tertiary STM HIG mill regrind . The wet plant was constructed
South Africa ' s Vibramech recently shipped its largest ever screens to Kenmare Resources in Mozambique
rates and without the need to use higher cost dry mining . As part of this ramp up in throughput , WCP A is being significantly upgraded which includes new desliming , screening and surge bin replacement .
Each of the the two Vibramech screens is mounted to isolation frames which weigh 17 t and utilise 44 rubber buffers . The company says that each screen drives three oil-lubricated geared exciters , that generate 40.85 t of force each . The expected total capacity will be up to 10,400t / h of slurry per screen , using polyurethane screening media .
While the large Vibramech screens use geared exciters , generally all screens below a weight of 18 t , are driven by URAS motors . Vibramech exclusively uses high quality Japanese URAS vibrating motors as it says they are robust , reliable , of the highest quality and offer long life . Vibramech are the exclusive agents for URAS motors on the continent of Africa , and stocks a wide range of URAS motors for use on its own vibrating equipment as well as for re-sale .
Overall , Vibramech says it is still working through busy order book that goes into 2025 already , with the workshop operating at a very productive and efficient capacity producing vibrating screens , pan feeders , grizzly feeders , and tube feeders not only for South Africa and the rest of Africa but also globally .
