BULK MATERIALS HANDLING

note

The combined project scope of these packages covers plant conveyors, stockyard, stacking and reclaiming machines, civil works, and electrical and instrumentation (E&I) work. The packages include installation of 14 machines and 79 conveyors, which in total handle mate- rial over a distance of 16 km, with the largest capacity conveyor rated at 4 000 t/h, operating at a speed of 3,7 m/s. Approximately 8 000 t of structural steel is being employed, excluding that for the scraper/reclaimers. TAKRAF Africa has completed the stock- yard and limestone material handling systems and is well advanced with the terrace package, having taken access within the fourth and fifth boiler units. The impressive safety performance on Kusile includes records of more than 2 million LTI (Lost-Time Injury) free hours being achieved, in many cases during complex and high-risk stages of the project. General industry Two material handling contracts were received from a leading South African cement producer for the supply of clinker handling systems. The projects cover, respectively, material handling for the loading of clinker onto rail and road transport systems from a silo at a facility in North West Province and, through the second contract, material handling for the rail unloading side at a clinker storage facility in the Eastern Cape. Both systems need to be tied into existing facilities during limited shut down periods to avoid production disruptions. In a third contract for the same cement pro- ducer, TAKRAF Africa is supplying the material handling system for a fly ash classification

plant in Mpumalanga. Interestingly, the mate- rial handling systems on all three projects are being equipped with TAKRAF dust extraction systems to reduce dust levels to within regula- tory limits. In other work for the industrial sector, TAKRAF Africa is supplying the complete woodchip conveying package as part of an expansion to a cellulose production facility in KwaZulu-Natal. This fast-track contract has called for the project to be completed within 11 months from order placement to commission- ing and involves 1 600 tons of steelwork. “These contracts make use of TAKRAF Africa’s wide product range, integrated into one seamless package. Both belt and Redler conveyors are being utilised on the woodchip conveying and clinker unloading systems, while the clinker loading contract in North West Province also features TAKRAF loading station technology.” Innovation “Without a doubt,” says Späth, “TAKRAF’s cul- ture of innovation is a strategic differentiator, evident across all our projects – across all sec- tors and across the globe.” In Chile for example, TAKRAF’s innovative
