201571 Fine, hydrophobic drug particles less than 5 μm 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 timeاحصل على السعر
2018419 INTRODUCTION. It is generally thought that as grain is ground to a fine mean particle size, a linear improvement in nutrient utilization and pig performance will be observed (Rojas et al., 2016).Research has demonstrated this benefit when particle size is reduced from 1,000 µm to approximately 400 µm in finishing pigs (Wondra et al., 1995b) احصل على السعر
