Why is conversion a measurable success?

Behind a real story

Indonesia has an annual economic growth rate of around 5%, making it one of the fastest growing regions in the world. Almost three million more people live in Indonesia every year. A relatively large proportion of investment therefore flows into the country’s infrastructure projects, among other things.

Cement is the core product of these infrastructure projects. Alongside Java, Sumatra is one of the regions with the highest demand for cement. Instead of new construction and high investments, many cement plant operators are opting for cost-efficient modernisation and the associated increase in output within the existing infrastructure.

At a cement plant in the south of the country, the operator decided to convert one of the two identical bucket elevators in order to generate more output and reduce energy consumption.

The customer decided in favour of a plant conversion by AUMUND: The friction lining, the steel cable belt, the profiled rubber strips, and the clamping connection were replaced. The conversion of the third-party bucket elevator with a centre distance of 71.5 metres was upgraded within less than a week.

The measurements in the following days confirmed the success of the conversion measures: a 15% reduction in energy consumption compared to the competitor’s machine and a 5% increase in conveying capacity. That was 400 tonnes more output per day thanks to the renewed bucket elevator.
