Six twin-shaft batch mixers of type DKX 6.0 are producing the concrete needed to build the main embankment of the Dagu hydro dam undergoing construction near the Tibetan city of Zangmu.
The construction site is located 3,700 m above sea level, making this the most elevated site ever for employing mixers from BHS. BHS specially modified the mixers to meet the challenges they are facing at this extreme altitude.
The first 2 mixers of type DKX 6.0 started producing the first batches of concrete in July 2017. Two months later, Sinohydro No. 9 Engineering Company commissioned 4 more units. The mixers will produce approximately 3 million tons of roller compacted concrete (RCC) over the course of the dam's construction, which is scheduled for completion in 2019. The complete facility, which comprises six mixers, is dimensioned to produce 160,000 m³ of hardened concrete per month.
The mixers are equipped with a coarse-grain mixing unit for processing grain sizes up to 160 mm.
