Recently commissioned and now fully operational the new stock house and conveyor at Tata Steel’s integrated steelworks at Port Talbot, now delivers up to a 1000tph of iron ore to the new no4 blast furnace.
Locally based Unifloc, who were appointed separate contractor for the new stock house and conveyor system delivered a turnkey project which included the feasibility study, the design, detailed engineering, supply, fabrication, project management, installation and commissioning of the whole materials handling system, including almost 1 kilometre of conveyors and 4 new bunkers having a combined storage capacity of 3600 tonnes of iron ore.
New HRI screens
As part of this project, Measham based Hewitt Robins International (HRI) were successful in the supply of two vibrating, single-deck 1800mm x 5500mm low angle Eliptex screens which were manufactured and designed to the Unifloc specifications to interface with the process line.
Both these screens were designed to process sinter with a maximum lump size of 50mm at a feed rate of 280tph and were supplied with WS85 Tema Isenmann polyurethane screen modules (side fixed).
Paul Burdienko – Projects Manager of Unifloc, commented, “HRI fulfilled our order and delivered two identical screens to our specification. Both these screens were fitted by our engineers and we are very pleased with the build quality and service provided by HRI.”
Both the HRI Low Angle screens supplied for the Port Talbot project utilise a twin shaft vibrator unit mounted above the screen deck impart a linear motion and allow easier decks replacement. Bespoke designed for long life they are of a bolted construction design allowing single component replacement. A wear resistant design offers ease of servicing and minimum downtime.
A spokesman for Tata Steel said, “Consistent flow of the burden is critical to the blast furnace process, a 24/7 operation. It is also important for us for working plant to maintain a high performance with minimum downtime; The HRI sinter screens are making a valuable contribution to the heavy-end of the steel plant producing liquid steel at a run-rate of approximately 4.3mtpa.”
