制药领域-颗粒的粒度在制药过程中,如加工、混合、压片和包装过程中起到非常重要的作用。药物的保存期和溶出率(控制药物对身体有利的溶出速度)也与颗粒的大小有密切的关系。

陶瓷领域-与粒径相关的信息有助于确定陶瓷制品固化和粘合程序,通过控制孔隙结构确保有足够的坯体强度,才能使最终产品达到所需要求的强度、质地、外观和密度。

油漆和涂料-颜料或填料的粒度分布可影响孔隙度、光泽、质地颜色、色彩饱和度、亮度、固形物含量以及薄膜粘接性能。由此形成的孔隙率可以控制应用性能,如流动性、干燥或凝结时间以及薄膜厚度。

化妆品-原料粉末,如滑石粉,和用于着色的颜料的粒度分布的情况可影响化妆品的外观、应用和包装。

Abrasives – Performance of abrasives, either in powder form or after being attached to a backing, is dictated by the size distribution of the abrasive powder. Over-sized particles lead to scratching and gouging. Undersized particles may lead to clogging of the abrasive papers.

催化剂-流动床催化剂的流动性取决于颗粒粒径分布的状况。酸性催化剂和催化剂载体的比表面积和孔隙结构因颗粒粒径分布的状况决定是否能用于生产。

Mining – Refining efficiency of materials is related strongly to the particle size distribution of the raw mineral. For products that are used without chemical change, the size of particles taken from the mine may be too large for final usage. Analyses performed on the extracted minerals will help determine the amount of size reduction needed once the product reaches the processing plant.

Column Packing Materials – The back-pressure of the packed bed within the column is a direct function of the size of the channels through the bed and, thus, the size distribution of the column packing material. Over-sized particles create voids in the bed, reducing efficiency due to remixing of the separated sample components. Undersized particles lead to blockage of flow paths through the bed, increasing the back-pressure and analysis time. A proper distribution leads to greater separation efficiency.
