Distribuirea mărimii particulelor influenţează proprietăţile fizice şi chimice ale materialelor solide. Prin urmare, acest criteriu este extrem de important în contextul ştiinţific şi al controlului de calitate. Numai dacă distribuirea mărimilor rămâne constantă se poate garanta o calitate stabilă a produsului, după cum arată următoarele exemple:
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 (...)
