Tenova TAKRAF, through Tenova SEMF, has just received the order from Sedgman for the supply of two identical radial coal stackers for the new Daunia Mine in the Bowen Basin coal fields of far North Queensland.

The scope of the contract includes the design, supply, delivery and provision of erection and commissioning supervision for the two radial stackers. The client is BHP Billiton Mitsubishi Alliance and the consulting engineers and mine developers are Sedgman.

The machines are identical to the ones just delivered to Lake Vermont and each are designed to receive and stockpile raw coal at the rate of 700 tonnes per hour to form two separate radial stockpiles each through 120 degrees for consolidating the coal prior to out loading by rail. The annual throughput for each machine is 2 million tonnes.

Each of the stackers has a boom length of 75 meters and is inclined from the fixed pivot at ground level at an angle of 15 degrees. They are supported on the bogies and running rail at 40 meters radius and can form a stockpile of nominally 20 meters overall height. The machines will operate fully automatically without the need of any on board operator interface.

Tenova designs and supplies advanced technologies, products and services for the metal and mining industries. Tenova operates close to its customers through a network of 30 companies based on the 5 continents.
