Summary

Generating an acceptable blend of powders and bulk solids presents frequent challenges across multiple industries, including chemicals, pharmaceuticals, foods, plastics, and batteries. Even when a "good" blend is achieved in a blender, segregation thereafter can occur at critical points where uniformity is essential, leading to rejected materials or defective products. Additionally, poor sampling practices often result in wasted product, out-of-control processes, and quality frustrations.

This webinar provides valuable insights for improving blending and sampling practices while addressing common segregation issues.

Topics covered include:

• Understanding mixing mechanisms

• Common mixers and blenders

• Best practices for sampling and sample handling

• Methods to avoid common segregation problems
