After intensive negotiations the Metallurgy Division of AUMUND Fördertechnik GmbH, Rheinberg, has now been awarded the order for the delivery of four each deep drawn pan conveyors, troughed chain conveyors and bucket elevators for the Sohar Pelletizing plant for the Vale Oman Industrial Project in Oman. At present, the Brazilian mining group Vale is working on the construction of the iron ore pellet plant in the port of Sohar, its first investment outside Brazil. The new Vale plant is located about 230 km to the north-west of Muscat and should produce up to 10 million tons of iron ore pellets per year. The commissioning is scheduled for the end of 2010. The plant will supply the whole Middle East with iron ore pellets for the steel industry.
During the order negotiations, the German specialist for the transport of hot and abrasive bulk materials could count on two references: AUMUND already supplied special conveyors for hot iron ore pellets for the Ardakan Pelletizing Project (Iran) as well as for GIIC (Bahrain).
AUMUND received from Vale the order for the delivery of two packages: The delivery scope of the first package consists of four identical deep drawn pan conveyors of type KZB 2000/350/6 and of four, also identical, troughed chain conveyors (TKF 800/2). The special conveyors with a center distance of 64 m and a conveying capacity of roughly 760 t/h receive the up to 300 degree Celsius hot pellet material from vibratory feeders. The max. possible handling speed would be 1,125 t/h. The pellets are transported by the deep drawn pan conveyors at a conveying speed of 0.24 m/s to a grizzly feeder. The troughed chain conveyors with a center distance of roughly 47 m are used beneath the pan conveyors to collect possible spillage material so that an almost maintenance-free operation is possible.
The second package comprises two belt bucket elevators (BWG 630/360) and two chain bucket elevators (BWZ-L 400/250). The AUMUND belt bucket elevators with a conveying capacity of max. 800 t/h and 23.5 m center distance are used to handle iron ore. The two chain bucket elevators transport pellets of max. 16 mm and a temperature between 350 and 400 degree Celsius at a conveying capacity from 10 to 50 t/h.
AUMUND will deliver the machines to Oman in the first quarter of 2010. The commissioning of the installation is scheduled for mid-2010.
In the field of hot material transport, AUMUND benefits from many years of experience gained with similar applications: The AUMUND conveyors offer a wide range of possible solutions for the transport of hot material in many different industries and lines of business. AUMUND solutions for the hot material transport consider individual requirements and are chosen especially where a continually high quality of the conveyed material has top priority. The AUMUND conveyors are capable of transporting solid material at a temperature of up to 1100 degree Celsius. For cooling down hot material, AUMUND supplies cooling conveyors with air or mist cooling or a combination of both.
