ふるい分けと分級 粒度分布は試料の物理的・化学的特性に大きな影響を与えます。したがって、粉体試料の粒度分布を知ることは、品質管理のなかでも重要な要素です。粒度分布が、いかに製品の品質に影響するかは、次の例でも明らかです。
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 (...)
