Segregation

Segregation refers to the unwanted separation of particles within a mixture, often caused by differences in size, shape, or density. This phenomenon can lead to inconsistent product quality, reduced processing efficiency, and challenges in material handling, particularly in industries like pharmaceuticals, food, and chemicals.

On this page, explore the causes of segregation, its impact on industrial processes, and strategies to minimize it, ensuring uniformity and reliability in your operations.

    Powder Flow vs. Powder Flooding: Where’s the Line?

    Powder Flow vs. Powder Flooding: An Introduction Smooth powder flow is usually the goal. But sometimes, flow becomes too good, resulting in uncontrolled discharge or powder flooding. This often surprises even seasoned engineers. Why? Because optimizing for flowability without understanding your powder’s behavior at rest and in motion can backfire. Let’s explore [...]
