The positive demand experienced by key equipment specialist TAKRAF Africa from the coal energy and power sectors has continued into 2018, with signs of a general revival in the mining industry, says Richard Späth, general manager – technologies.

“TAKRAF Africa ended 2017 on a high note, delivering strong performances, both financially and in terms of project delivery,” says Späth.

New awards included an order from a power station for a train wagon tippler system upgrade, including associated conveyors, with the tippler having a capacity of 8 000 tph, unloading rates in excess of 100 wagons per hour.

It includes positioners and ancillary equipment, as well as a dry fog suppression system.

Also in 2017, two semi-mobile Bradford breakers were supplied within a year of TAKRAF Africa unveiling these innovative machines to the market.

“The machines, supplied for junior open cast coal miners Overlooked Colliery and Black Wattle Colliery in Mpumalanga, offer the benefits of the traditional breaker in a more compact machine,” adds Späth.

TAKRAF Africa’s solid/liquid separation specialist, Delkor Africa delivered two Delkor high rate thickener drives and internals to a coal mine in Limpopo.

The drives are part of an order that covers the supply of four thickeners over a three year period.

“Our air environmental services continue to experience buoyant demand across a wide range of  commodities, with, for example, TAKRAF Africa supplying the DSI fog dust reduction systems to two power stations, while there is growing interest from clients in the DSI DustTamer Wind Fence for stockpile protection.”

TAKRAF Africa is also continuing work on the lump-sum turnkey materials handling project for Eskom’s Kusile power station, the largest bulk handling project to be awarded to the company.

A century of innovation and service to the coal industry

Through its heritage as part of the Bateman Group, TAKRAF Africa has worked with almost every coal producer in southern Africa over a track record spanning nearly 100 years.

“Our continued success in this market, firstly as Bateman and then as TAKRAF Africa since 2012, following the acquisition of the Bateman Group by Tenova, is due to a combination of factors,” says Späth.

“Prime amongst these is our comprehensive source of in-house expertise, supported by ongoing innovation and technology acquisition.”

 

“Coal granulators do not produce a high volume of fines and also offer considerable cost savings due to their lower power requirements and service and maintenance features,” notes Späth.

TAKRAF Africa’s in-house minerals laboratory to conduct material tests across various conditions in order to determine factors such as material crushability and wear behaviour, which are important in sizer selection.

Amongst TAKRAF Africa’s extensive list of ‘firsts’ is the first rapid rail load out station in Africa. TAKRAF Africa’s stations uses a flask-loading system and feature a built-in “learning capability” for exceptionally accurate loading of the wagons.

TAKRAF apron feeders are employed both in mining and processing operations.

With minimal maintenance requirements, they are installed below dump hoppers, and at material storage or transfer facilities, and can be used with the feeder slope inclined up to 18°.
