Mixing Mechanics: Practical powder blending: Failure modes
As an essential part of the manufacturing process, powder blending can come with challenges. This article details some of the common failures in the process and offers recommendations to prevent them.
Powder blending is one of the most common processes in the industry, an essential part of the manufacturing sequence of pharmaceuticals, catalysts, glass, cement, detergents, agrochemicals, food, cosmetics, ceramics, polymers, and resins, to name but a few. Blending is also a poorly understood process step, where errors in process design and poor choices in sampling methods often lead to process failures. This column is the first in a series that will provide recommendations for avoiding some of the most common mistakes in designing and scaling-up batch blending processes.
