Pneumatic conveying at 5.1 km is longest in the world

Claudius Peters, builder of which is considered to be the world's longest pneumatic conveying system, supplies a bespoke pneumatic transport system capable of conveying distances of more than 1100m to LafargeHolcim, Indonesia.

Holcim’s new state-of-the-art Tuban plant has been designed for the highly-efficient production of cement, setting new benchmarks in health and safety, low-cost production and environmental performance to Indonesia’s growth markets. The plant has an annual cement capacity of 3.4 million tonnes and is located in Eastern Java around 200 km from the city of Surabaya.

Prior to supplying the conveying equipment, the customer was invited to view a full scale pneumatic conveying test system in the Claudius Peters Technikum (technical centre) at the group’s headquarters in Hamburg, Germany, where it successfully conveyed cement across a distance of more than 1km, proving the feasibility of a transport system of this scale, which at 5.1km, is the longest of its kind.

The conveying line supplied to Holcim not only conveys over long distances but thanks to higher availability and lower investment costs presents itself as a viable alternative to regular mechanical conveying systems.

The Claudius Peters company was established in Hamburg, Germany, in 1906 by its eponymous founder. The company, which employs around 600 people, has been part of the British engineering group, Langley Holdings plc, since 2001.
