Head Pressure In Your Hopper: What Is It, And How Do You Mitigate It?

What is head pressure in your hopper and how does it relate to tablet press performance?

Head pressure in a hopper refers to the pressure exerted on the formulation due to the weight of the powder on top pushing on the powder below it. This can cause the formulation to become cohesive and form arches or ratholes, negatively impacting flow. Flooding can also occur when powders collapse and uncontrolled flow. To prevent this, a mass flow pattern should be established where all material is in motion. Take a deeper look at these preventative measures, strategies to achieve a steady flow, and why head pressure is crucial for tablet manufacturers to optimize their press performan
