AUMUND Fördertechnik, Rheinberg, Germany, recently won an order to supply one of its KZB-H pan conveyors to the Port Latta pellet works operated by Grange Resources (Tasmania) Pty Ltd. It will transfer hardened iron ore pellets with a temperature of 750°C from the shaft furnace to the cooler at a rate of 500t/h. The conveyor, which will have a length of 92m and a plate width of 1000mm, s designed to handle hot material up to 1000°C. It will replace the existing belt conveyor at Grange, which previously had to have its belts changed approximately every 40 days, increasing production costs due to the frequent stoppages, on top of the expense of the new belts and the labour to change them.

One of the big challenges for AUMUND Fördertechnik was the difference in dimensions of the new steel plate conveyor compared with the previous belt conveyor. It is important that the process stages are connected by optimised technical solutions because any shutdown of this conveyor would immediately stop the operation of the whole plant. The engineers of AUMUND’s Metallurgy Division explained the design and process solution in a day-long evaluation meeting. This approach gave the AUMUND specialists an advantage over the competition. Another decisive factor in winning the order was accompanying the customer on visits to two reference plants.

Commissioning of the AUMUND steel plate conveyor at Port Latta in north-west Tasmania is planned for April or May this year. www.aumund.com
