Paper sack recycling loop

When the Packaging Ordinance came into force on 01.01.1993, the German economy was bound by law for the first time to return packaging after use and play an active role in its disposal. Since then the ordinance has been continually refined – most recently with the introduction of the seventh amendment – in order to constantly improve the process of returning packaging and prevent abuse of the system.

Vibration monitoring to boost efficiency

Cement manufacturing is one of the most aggressive of all production processes. The chemicals used to produce Portland and Masonry cement – particu­larly silicates, aluminates and aluminoferrites – can combine to create high levels of very fine particles, creating significant problems for production and handling equipment. Rotating components are at greatest risk, and they are commonly found in the motors, pumps and fans used in crushers, mills, precipitators, kilns and silos. ...

Advances in physical properties of C class fly ash cement systems blended nanographite – Part 1

Research results suggest that the use of nanographite in the CFA-C system and the pure cement system accelerate the setting time and increase the strength gains, hence overweighing any negative effects. The water absorption, apparent volume, apparent density, CH-content, setting time, fluidity and strength gain are favourable when compared to pure cement and nanographite-blended cement. Part 1 discusses materials and methods, whereas Part 2 will focus on the results and conclusions.
