Bulk solids expert Kerry Johanson answers a reader’s question about how to discover the mixing efficiencies of various mixers.
There’s no book or table that contains general information on mixing efficiencies of various mixers. The act of blending depends on a combination of several factors: blender style, material characteristics, and operating conditions. Mixing efficiency is a convoluted combination of the influence of key flow properties, specific blender geometry, and blender operation parameters. Changing any of these will change the blender efficiency.
