Cure Segregation & Improve Blending

What Are Segregation & Blending?

Segregation results when particles separate due to differences in their size, shape, or density. Segregation can result upon handling of a powder blend or material with varied particle size. Common segregation mechanisms include, fluidization, and .

Blending (or mixing) is the opposite behavior of segregation. The process of blending occurs when a collection of particles is homogenized or multiple ingredients are mixed to obtain a uniform product. Some materials require gentle tumble blending in a controlled batch mode while others require high shear to continuously blend highly cohesive and tough-to-mix ingredients. A well-blended material does not guarantee production of a quality product due to segregation effects that may result during powder flow.

When & Where can Segregation Occur?

• Rejected product
• Variable color, look, or taste
• Excessive blend times
• Customer complaints
• Erratic dosage weight, mass
• Product or process delays
• Inconsistent particle size
• Poor quality control
