A cut above the rest11 March 2014, Published under Cement NewsIrish Cement, part of the CRH Group, has been producing cement for more than 60 years. To maintain its competitive advantage the company must operate its facilities in optimal working condition. So when the cement producer was faced with removing a section of the kiln at its Limerick plant in County Limerick, Ireland, it turned to Gullco International to facilitate the removal and replacement of one of the kiln tyres. By Nick Drake, Gullco International Ltd, UK. Irish Cement replaces ... |
Maximising AF usage25 February 2014, Published under Cement NewsWhile the use of alternative fuels (AF) continues to increase, the desired targets always pose challenges as the price and properties of waste-derived fuels vary. Therefore, a better understanding of AF utilisation is essential to mitigate any potential negative effects on kiln stability, product quality and emissions. The case study detailed below highlights the effectiveness of using MI-CFD as an engineering tool to reduce CO emissions when AF is co-fired with coal at the kiln front-end. B... |
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... |
The benchmark cooler12 February 2014, Published under Cement NewsThe Best Available Techniques CO2 emissions benchmark reference of 2900-3300kJ/kg clinker now applies to new cement plants. The component with the highest potential for savings within the clinker production process is the clinker cooler. Claudius Peters demonstrates how to utilise this potential based on references including Lafarge, Holcim, Anhui Conch and one of its latest projects for Najran Cement. By Ulrich Mrowald, Claudius Peters, Germany. Claudius Peters’ ETA cooler has been d... |
Pressing matters04 February 2014, Published under Cement NewsSince the 1980s, roller presses have been in demand for their high levels of efficiency and energy conservation, and their development has reached an advanced level of maturity.
