Measuring Particles More Precisely and Efficiently
The use of digital image processing in particle analysis has made significant progress with the availability of new algorithms from Retsch Technology GmbH (Haan, Technology). At POWTECH 2004 (16-18 March 2004, Nuremberg, Germany), Retsch will present new developments in the particle analysis systems CAMSIZER(r) and CRYSTALSIZER(r) which are said to make particle size and shape analysis easier and more efficient. These devices cover a measuring range of 0.7 micron to 30mm.
Only since the introduction of digital image processing into a particle measuring device has it become possible to precisely measure the shape of particles, thus achieving fast and reliable characterisation of powders and bulk materials for quality assurance.
With the new software upgrade it is now possible to compensate for the differences between various measuring techniques and the CAMSIZER principle. In this way, it is possible to perfectly match the results of the traditional screen analysis, which is often used as a basis for a variety of standards used in digital image processing.
In addition, the user receives information on conformity parameters such as absolute lengths, width/length ratios, symmetry and roundness. The CAMSIZER significantly lowers the amount of time and work expended for particle analysis when compared to traditional methods such as sieving.
Retsch said that, apart from the high degree of efficiency, the results offer a very precise image of the sampling material. Moreover, the new software supplies daily reports and analyses, thus allowing rapid and easy assessment of changes in material and production processes, even over long periods of time. This helps ensure uninterrupted quality assurance.
