thyssenkrupp tech­nol­ogy in­creases ef­fi­ciency

The Australian Mining Review - - BHP IRON ORE -

THE coal ter­mi­nal at the port of Caofei­d­ian is a ma­jor hub for sup­ply­ing power plants in the south of China.

Coal from the mines in the north of the coun­try has been brought by train to the port for on­ward ship­ping.

In the past few years thyssenkrupp has sup­plied Caofei­d­ian with eight ship load­ers and two quadru­ple rail car dumper sta­tions for speedy un­load­ing.

Each of these two new dumper sta­tions can un­load four 80-tonne ca­pac­ity coal cars at a time.

The four cars were po­si­tioned in the dumper so that they ro­tate around their cou­pling axis and at the same time dis­charge their loads into the silo be­low.

The po­si­tion­ing of the full train and emp­ty­ing of the next four cars has been con­trolled by a po­si­tioner (in­dexer) to en­sure fast and re­li­able un­load­ing.

The po­si­tioner trav­els par­al­lel to the track and in­dexes the en­tire train.

The car cou­plers them­selves were ro­tary cou­plers, so it was not nec­es­sary to un­cou­ple the cars from the train.

The po­si­tioner pushes the en­tire train with a to­tal of 204 cars and four lo­co­mo­tives; the lo­co­mo­tives are not re­quired to move or slow down the train at any point in the un­load­ing process.

As soon as all the cars have passed through the dumper and dis­charged their con­tents, the lo­co­mo­tives take over again to move the emp­tied train out of the port.

In this way a quadru­ple dumper was ca­pa­ble of han­dling 8640 tonnes of coal per hour, which means an en­tire train can be un­loaded in just two hours.

Each of the dumper sta­tions was fit­ted with a dust col­lec­tor, fresh air ven­ti­la­tion, and a wa­ter sprayer for dust con­trol.

Vi­bra­tors on the dumper bar­rel en­sure all coal residues are re­moved from the cars.

Cam­era sys­tems have been in­stalled to al­low mon­i­tor­ing of the en­tire un­load­ing process.
