7 October 2009: Malvern, UK: New experimental results highlight the Mastersizer 2000 from Malvern Instruments as a reliable and practical solution to the cement industry's growing need for reference laboratory particle characterization systems. Not only does the Mastersizer 2000 deliver data that correlate more precisely with the performance of finished cement than traditional Blaine numbers, but the system is also valuable in analyzing other important process streams. A new, freely available application note - Particle sizing in cement - describes how the Mastersizer 2000 meets cement industry requirements for reproducibility and flexibility as well as rapid, automated measurement. www.malvern.com/appnote_particle_size_cement
Within the cement industry, laser diffraction particle size analysis is rapidly replacing Blaine surface area measurement for characterizing product fineness, a key performance indicator. Suitable only for laboratory use, Blaine measurements provide just a single number description of a sample. In contrast, laser diffraction measures the entire cement particle size distribution, allowing product performance to be specified more precisely. The implementation of the technique in the Mastersizer 2000 laboratory system, and in the Malvern Insitec at-line and on-line systems, simplifies the transfer of knowledge and specifications between the laboratory and manufacturing plant, creating opportunities for process optimisation and economic gain.
The Mastersizer 2000 measures across a broad dynamic range. Consequently it is ideal for analyzing the many different sample types encountered in central research and quality control laboratories, from finished cement of all grades, through to replacement materials such as blast furnace slag and fly ash. A range of cement dispersion units is available for both wet and dry dispersion. Cleaning and sample loading are easy, while Standard Operating Procedure (SOP)-driven operation gives excellent repeatability, even for non-expert operators.
The Mastersizer 2000 is part of Malvern's complete range of analytical systems for cement manufacture, which includes Insitec at- and on-line systems for continuous use within the process environment. In combination this unique offering comprehensively fulfils the laser diffraction needs of the cement industry, helping manufacturers to improve control, drive down production costs and reduce environmental impact.
