Materials & quality: 30 years on10 July 2018, Published under Cement NewsThe development of new cement types and demands on fuels as well as changes in process requirements have led to key changes in cement production over the last three decades. New raw materials and alternative fuels have given rise to new cement standards. Alternative raw materials increasingly reduce the need for virgin materials The cement Industry in 2018 has been through a long period of soul searching and reorganisation which has involved multiple changes in ownership and adj... |
Keeping your cool17 April 2018, Published under Cement NewsYanbu Cement Co looks at the importance of optimising cooler operation in managing a cement plant’s energy consumption and protecting downstream equipment. By Amr Nader, Yanbu Cement Co, Saudi Arabia. Figure 1: Yanbu Cement Company process optimisation objectives and footprint One of the strategic goals set by Saudi cement producer Yanbu Cement Co (YCC) is to maximise asset utilisation at the lowest specific thermal and electrical energy but the highest-possible quality (see Fi... |
Crystal inclusions in Portland cement clinker10 August 2016, Published under Cement NewsThe nature of inclusions in clinker crystals provides clues about the burning environment and are therefore important indicators of clinker quality. Figure 1: blue belite inclusions in alite crystals Of the four main crystalline compounds that are found in Portland cement clinker, two are produced as solids and two are present in the burning zone of the cement kiln as a liquid, which then crystallises on cooling. Microscopic examination of clinker has been employed as a quali... |
Kiln feed and clinker quality16 December 2013, Published under Cement NewsCommissioning a new cement plant generally centres around the performance in terms of tonnes per day, kWh/t, or other operational matters. It is easy to lose sight of the need to achieve the required quality while fulfilling these other requirements. The following article describes a case study of quality issues and the means of improvement during the commissioning of a 4000tpd precalciner kiln. Coarse (brown) alite crystals, coarse prismatic C3A and degraded alite indicating poor-qua... |
The lifecycle of a tyre13 June 2013, Published under Cement NewsThe use of alternative fuels and raw materials is common practice in the European cement industry. In this excerpt from MVW Lechtenberg & Partner’s Alternative Fuels & Raw Materials Handbook, the company gives an overview of scrap tyres as an alternative fuel highlighting the economic value for usage in cement plants, the impact on clinker quality as well as considerations and recommendations.
