Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control. Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:
Despite the rapid development of modern optical particle measuring techniques, classical sieving analysis is still at the forefront for the practical quality assurance of bulk goods.
In addition, sieving results are often used as the basis for comparison with other measuring techniques. Above all, a quickly available particle size determination result is required for the quality assessment of bulk goods during production processes. In order to ensure proper production monitoring, it is frequently quite sufficient to determine a trend.
Standardized and reproducible working instruments are required in order to ensure the reliability of the results and to reduce the required working time to the absolute minimum (...)
