The importance of raw materials17 February 2014, Published under Cement NewsProper analysis and identification of raw materials are essential to achieving the best clinker in the kiln. All clinkers will have a small degree of unwanted elements, but much can be learnt about reaching the desired levels of strength, setting time and crystal content by understanding what makes good- and poor-quality clinker. For a new cement plant the main raw material selection is generally the first and most important phase of development. If the everyday supply of limestone is not... |
Swiss cement industry to solve future raw materials shortage27 January 2014, Published under Cement NewsFive out of six cement plants in Switzerland are expected to run out of limestone and marl over the next 10-15 years. As their existing quarries border areas with protected status as landscapes of national significance, they can not be readily expanded. “We have to find a solution that enables a reduction in these areas,” says Georges Spicher, director of cement association cemsuisse. However, the negotiations with the federal government, the cantons and communities are likely to be dif... |
Consistent, reliable results26 November 2013, Published under Cement NewsQuality control has been automated to such an extent that we run the severe risk of turning into a generation of button-pushing operators instead of thinking analytical scientists. It is imperative that analytical scientists responsible for the quality control in a plant remain vigilant and regularly evaluate their data because automated sampling systems, plant process control systems, analytical equipment and data management systems need so little human input once set up correctly.

Using multiple raw materials17 July 2013, Published under Cement NewsThere are very few cement plant locations where a single, locally-available raw material source will be suitable for producing cement clinker. Even when the quantity of imported material is small, the costs of transporting, handling, proportioning and feeding extra raw materials can mount up and with each additional material another variable is introduced. So how does the benefit of sweetening the mix weigh against the disadvantages? How does the benefit of sweeting the raw materials ... |
