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.

    Thermal Gradient Segregation: Why Heat Moves Particles

    Thermal gradient segregation begins when one region of a system gets warmer than another and the composition slowly drifts out of balance. In most bulk vessels, natural convection is the first mechanism to check. Fluid near the hotter zone expands, becomes less dense, and rises. Cooler material sinks and closes the circulation [...]

    Powder Segregation Diagnosis During Mixing, Conveying, and Filling

    Powder segregation diagnosis starts by locating where the blend loses uniformity. Some blends leave the mixer in spec and drift only during transfer, filling, or discharge. In practice, the main mechanisms are sifting, fluidization, trajectory segregation, and dusting. Each one is triggered by a different combination of particle properties, airflow, and equipment geometry. [...]
