Jul 01, 2015 Fine, hydrophobic drug particles less than 5 m in size are known to be exceptionally prone to agglomeration and this is attributed to the inter-particulate cohesive forces between them. Hence, when milling is prolonged, particle agglomeration may supersede particle fracture and this severely reduces the efficiency of the mill over time.
