Distribúcia veľkosti častíc má vplyv na fyzikálne a chemické vlastnosti pevných látok. Z tohto dôvodu je toto kritérium veľmi dôležité v oblasti vedy a merania kvality. Iba v prípade konštantnej distribúcie veľkosti častíc môže byť daný produkt stabilne kvalitný, ako ukazujú nasledujúce príklady:
Many natural and manufactured materials occur in a disperse form, which means that they consist of differently shaped and sized particles. The particle size distribution, i.e. the number of particles of different sizes, is responsible for important physical and chemical properties.
Such as:
• mechanical bulk behavior
• surface reaction
• taste
• miscibility
• filtration properties
• conductivity
This list could be continued at great length. The examples clearly show how important it is to have a knowledge of the particle distribution, particularly within the context of quality assurance in the production of bulk goods. If the particle distribution changes during the manufacturing process then the quality of the finished product will also change. Only a continuous monitoring of the particle size distribution can guarantee a constant product quality.
