Aury Africa has stated that it aims to bring its first dry separator to South Africa for trial at a coal mine in 2019. The company, which is a subsidiary of design and construction coal group DADI Engineering Development Group, is in discussions with its sister company Meiteng Technology Group to bring its Telligent Dry Separator (TDS) to the local market.

Aury Africa to bring first dry separator to SAThe TDS uses intelligent dry separation technology, allowing it to essentially convey coal on a single layered enclosed conveying system. The enclosed system, which incorporates dual X-ray technology, accurately identifies and separates coal without using water or any other medium. There is also no slime generation, with the TDS subsequently producing a higher yield of coarse coal at low operational cost at an increased return-on-investment, compared to conventional process systems, according to Aury Africa.

The technology can process 300 mm to 50 mm and 100 mm to 25 mm raw coal, with an upper throughput of about 400 tph. “The higher tonnage output makes the TDS more efficient compared to competitor dry sorter technology. Aury Africa is continuously striving to improve the technology’s separation capabilities in order to achieve coal sizing down to 12 mm,” says Aury Africa Managing Director Sydney Parkhouse.

The technology is fully automated and modular, with a self-diagnostic system. “The longer the unit runs, the more accurate it becomes – the margin of reject material compared to coal is reduced, as the TDS learns and adapts continuously,” Parkhouse adds.

Aury Africa Production and Support Manager John Wills points out that the fact that the TDS does not use any water during operation makes it a fundamentally invaluable technology for ‘greening’ the coal-mining industry. “There is increasing focus from mines to be environment-friendly, with significant pressure on the coal industry to go ‘green’ – this technology is a push in that direction.”

According to Parkhouse, Aury Africa is considering different applications for the TDS in the complete mineral beneficiation chain. For example, a four tonne sample from a manganese mine in the Northern Cape was sent to Tianjin in China in July for separation trials using the TDS.

Business Development Manager George Sturgeon says that Aury Africa is inviting interested mining companies to submit their mineral samples to be trialled on the TDS, until such time as the equipment available in South Africa. The mineral and reject material must be trialled to differentiate X-ray absorption rates, and the computer software is programmed by the development of algorithms during the trialling period, after which the equipment is set up accordingly.
