THE benefits of the Transmin low profile feeder (LPF) have been well felt throughout the mining industry, particularly by the Utah Point berth project in Port Hedland, WA. The Transmin LPF offers a range of benefits compared to alternative feeder designs: most notably, when compared with conventional belt or apron feeders, the LPF’s combination of both apron and belt technology allows it to offer increased efficiency and far greater versatility.
When QUBE Bulk Logistics (formerly POAGS) opened in September 2010, Transmin fulfilled a contract for 11 machines to handle various grades of iron ore and minerals at Utah Point. The
operation of the multi-user stockpile facility required LPFs to accept incoming material from side-tipping trucks, with each LPF incorporating an integral 11m-long inlet hopper capable of receiving a dumped load of 50t.
The Transmin LPF is available in a range of standard belt widths, from 1.2m to 4m, and Transmin can cater for customised designs tailored to customer specifications and material characteristics.
Machine capacities vary according to application, although rates of 500 tonnes per hour are readily available. Further design advantages ensure the Transmin LPF will not mistrack or slip.
The belt is positively driven by toothed sprockets and securely attached to cross slats driven by standard twin D-type track chain, for maximum durability. Because the design of the Transmin
LPF utilises common industry components, spare parts are easily accessible and appear familiar to maintenance staff, for ease of servicing and repairs. An additional ‘user friendly’ component, ideal in tight installations where space is a premium, sees the belting fitted in modular sections, allowing each to be replaced separately rather than having to replace the entire belt.
Transmin business development manager Phil Gilbert said there had been an increase in enquiries from customers interested in utilising the company’s LPF for heavy duty applications in the
iron ore sector of the mining industry. “The technology is being rapidly established, which is demonstrated by Transmin’s recent award for three D6-18 LPFs to handle minus-400 millimetre
iron ore at nearly 3000 tonnes per hour,” Mr Gilbert said.
“Each of these machines is located beneath a large storage bunker and subjected to high head loads necessitating the use of large drives. “These machines are destined for installation at a new iron ore project in the Pilbara region in Western Australia during the third quarter of 2012.” Transmin has reported that its LPF can also be utilised for applications including stockpile reclaim, bunker extraction, crusher and screen feeding, furnace and kiln feeding, and bulk vehicle or front-end loader intake.
