Low-bulk-density powders with small particle size, low to zero moisture content and low to no cohesiveness can become easily aerated during bulk bag filling leading to poor bulk bag densification. In addition to especially challenging lightweight powders, many other powders, pellets and granules’ material properties make them prone to aeration during filling and difficult to compact. In fact, reducing the amount of air that enters into the material during the filling process is one of the greatest technical challenges in bulk bag filling.

This article will:

• define and discuss the relationship between aeration and densification
• outline the challenges and risks that arise from aeration during the filling process
• discuss bulk bag filling system solutions to increase bagged material density
