Motionless Mixers in Bulk Solids Treatments – A Review

In this paper the general features, behavior and application possibilities of motionless mixers in mixing and treatments of bulk solids are overviewed, summarizing the results published during the last three decades. Working principles, mechanisms, performance, modeling and applications of these devices are described. Related topics, such as use in particle coating, pneumatic conveying, contacting, flow improvement, bulk volume reduction, and dust separation are also summarized.
