Key global mining, materials handling, minerals processing and equipment supplier, TAKRAF Africa is seeing growing demand in Zambia for a wide range of its technologies, from conveyor and stockyards systems through to dust control and solid liquid separation equipment.
With the ability to provide innovative and advanced technologies and equipment from pit to port, TAKRAF Africa covers applications ranging from open cast mining, through bulk and specialised materials handling, and air environmental control, to ship loading and unloading.
This is supplemented by the DELKOR offering of specialist technologies for solid-liquid separation and mineral processing applications.
The demand is underpinned by its reputation as a supplier of world class equipment tailored to the unique needs of local mining conditions, combined with TAKRAF Africa’s extensive track record of involvement in many of Zambia’s leading mining projects.
“As part of the Bateman group prior to it being acquired by Tenova in 2012, TAKRAF Africa has been supplying equipment into the African continent for nearly 100 years,” said TAKRAF Africa’s General Manager – Technologies, Richard Späth.
“Successfully delivered contracts range from a 4.5 km overland conveyor system to feed copper ore from the then newly developed Chimiwungo pit at Barrick Gold’s Lumwana copper mine, to the supply of bridge reclaimers for handling copper concentrate, DELKOR horizontal belt filters and flotation cells for Vedanta Resources’ Konkola Copper Mines.
“Copper concentrate bridge reclaimers were also supplied to First Quantum Minerals’ Kansanshi Mining, in addition to two pinned bed clarifiers, which were ordered following their successful installation at its Bwana Mkubwa copper mine.
“A luffing stacker and side scraper-reclaimer for a small capacity coal handling system for the Thermax-captive power project for the Dangote Group in Zambia was the fourth project carried out by TAKRAF for the Dangote Group,” adds Späth.
Other orders from Zambia for TAKRAF Africa equipment have ranged from pinned bed clarifiers for ERG’s Chambishi Metals to supply of a TAKRAF apron feeder, dynamic scrubber, filter press unit and high rate thickener mechanism to Glencore International’s Mopani Copper Project. The thickener mechanism was retrofitted into an existing thickener tank.
Conveyor Systems
Designed to ISO and CEMA standards, TAKRAF conveying systems cater for any plant, overland or stockyard conveying need, providing high speed and high capacity and the ability to handle difficult material. Long curved overland belt conveyors include curved regenerative downhill and high lift troughed belt conveyor systems, some of which are amongst the longest in the world.
Stockyard Systems
TAKRAF Africa supplies a complete range of machines for stacking, reclaiming, homogenizing and blending. The range covers stackers with boom lengths up to 70 m and rates of up to 20,000 t/h. Tenova TAKRAF bucket wheel and bridge type reclaimers have capacities up to 15,000 t/h and up to 10,000 t/h, respectively, with the bucket wheel reclaimers offering the largest reclaiming capacities compared to other designs. Combined stacker/reclaimers offer the advantage of reducing the number of machines on a stockyard, with stacking/reclaiming rates of up to 12,000t/h.
Apron Feeders
TAKRAF apron feeders are designed for use in demanding material handling and processing applications and cover a range of mineral commodities, as well as various ore, coal and aggregates. Combining heavy-duty frames with standard chains and rugged pans to provide an extended service life, the diverse product range covers standardized apron feeders, as well as specific heavy-duty feeders with large handling capacities exceeding 10,000 t/h.
Dust Control Systems
TAKRAF Africa has supplied Africa’s mining industry with more than 3,000 dust control systems over the past 50 plus years. The comprehensive in-house range cleans the air over the entire process chain and covers reverse jet and reverse pulse bag filters, scrubbers and the electrostatic precipitator, an economical system capable of reducing dust content of more than 1,000 g/m3 to any required residual dust content. A recent addition to the range is the DSI dry fog suppression systems. Beside their performance, the many benefits of the DSI systems include ease of installation, simplified maintenance, flexible system configuration and reduced capital investment and operating costs.
Solid-Liquid Separation
TAKRAF Africa’s offers a comprehensive range of DELKOR solid-liquid separation technologies, covering flotation, sedimentation, filtration, screening and gravity separation systems.
The DELKOR F.A.S.T.TM Filter Press is a reliable and fully automatic filter press that offers flexible operation and easy and low maintenance. It is suitable for a wide range of dewatering applications, from minerals concentrates and tailings to very fine materials in the chemical, iron and steel, food processing and water treatment sectors.
The DELKOR thickener range offers designs up to 100 m in diameter, catering for a variety of applications in the minerals, industrial, chemical, water treatment and waste water industries. The range covers high rate thickeners, high density thickeners, paste thickeners, conventional thickeners and sludge bed clarifiers. With a number of installations already on Zambian mining operations, the pinned bed clarifier removes suspended solids in liquor feed solutions in hydrometallurgical plants and other solvent-extraction units, to less than 30 ppm.
