New fluid coupling doubles productivity in Chinese coal mine

An additional 350,000 tpm of coal production has been made possible at the Chinese Sandaogou coal mine in the Shaanxi province, largely because of CPC 1600 AFC (armoured face conveyor) couplings installed at the mine. This fluid coupling can continuously transmit up to 1600 kW, roughly 60% more power than standard fluid couplings of comparable installation space. The XL profile design turbine wheel helps the fluid coupling achieve these statistics.

To be able to efficiently mine a coal face measuring 7 m high, 350 m wide and more than 3 km long, the operator of the Sandaogou coal mine required powerful equipment. Existing drive systems were not able to transfer the necessary power to the conveyor. The CPC 1600 couplings combine maximum power transmission and small size. Orders for three CPC 1600s have been delivered and are currently in use in the Chinese Sandaogou coal mine.
