The system consists of a large-scale BWE SRs 2000 (rated capacity 6,600 cu metres/hr) with loading unit, a 7,750m long conveyor system consisting of five flights, as well as a compact spreader with tripper car on rails.
The BWE reaches 30 m digging height, and although it has a service weight of about 3,300t, it has a ground pressure much lower than that of a D11 Dozer. In order to properly handle peak capacities the conveyor system, as well as the spreader, have a design capacity of 7,900 cu metres/hr. The conveyors running along the excavator bench and along the waste dump are shiftable.
The project commenced in September 2009 with the BWE, spreader and conveyor system awarded in three stages from 2009 to 2011. The complete turnkey project covered design, supply, transport, on-site installation, commissioning and testing.
The project site is located approximately 700 km from Beijing in remote northern China, where the extreme climatic conditions see winter temperatures of down to -40 Deg-C and summer temperatures of up to +40 Deg-C.
The project is regarded as an important milestone in the development of China’s mining industry, typified by a trend towards larger scale mines and mining equipment.
Tenova Takraf previously supplied two BWE systems to Yuanbaoshan in the 1990s.
