The use of digital image processing in particle analysis has made significant progress with the availability of new algorithms from Retsch Technology. New developments in their particle analysis system CAMSIZER® make particle size and shape analysis easier and more efficient. The device covers a measuring range of 30 µm to 30 mm.
Digital Image Processing for Grain Size and Grain Shape Analysis
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. Apart from the high degree of efficiency, the results offer a very precise image of the sampling material. Moreover, the new CAMSIZER® software supplies daily reports and trend analyses, thus allowing rapid and easy
