  • 2021-08-05 The large power demands of finish milling mean that improved monitoring of the grinding efficiency and optimization of the classifier speed yields an in-specification product with significant energy efficiency improvements and ultimately cost savings. This is best achieved by having a laser diffraction which is quick and easy to use with consistent repeatable results being attained no matter which operator is using the system. In addition, by having control standard results for each cement grade maintained inside the computer database, all newly produced cement for all grades can be compared in seconds to the ideal products fineness parameters. The Bettersizer 2600 has all this functionality in its software and provides the rapid laboratory fineness analysis to prove the cement meets the specifications and is thus fit for purpose.

  • 2021-07-09 The improvement of drug quality is the basic principle for developing overall strategies. For the current evaluation system, dissolution is a top priority, and the particle size of the pharmaceutical preparation has an important influence on the dissolution curve. However, everyone still faces a lot of confusion about particle size analysis. For example, the results of different test conditions are different, but which one is more reliable? Why do some samples have different results from different manufacturers? Whose granular results are closer to "truth"? This application note demystifies these questions.
