Eskom, Majuba Power Station – Mpumalanga, South Africa
Majuba Power Station Coal Silo Recovery Project.
This system was the permanent reinstatement of the collapsed Silo 20 and associated conveyors. The system included: • Reinstatement of two coal Overland Conveyors: 1.5km at 3260T/h each, including new drive station and take-up and new online elemental analyser • Installation of a moveable belt plough on each of the overland conveyors to allow for coal to be diverted onto the bypass system if necessary. This plough technology was a first in South Africa • Reinstatement of the four Oversilo Link Conveyors: 170m at 3260t/h each • Two new undersilo belt feeders: 21m at 1200t/h each • Reinstatement of complex and extensive structural steel, including three 30m (70 tons each) gantries, and a transfer house (110 tons), all at a height of 60m above ground The structural scope included the design and construction of all conveyor support structures, access walkways and staircases, and transfer points. Time constraints were a major factor and the entire project was completed in 14 months. Creative methods of pre-assembly and rigging, particularly at the top of Silo 20 (approx. 60m high) were key to completing on time.
