Testing a Continuous Mixer

A continuous mixer cannot be tested reliably without a reliable feed system for the components. The feed system should be capable of turndown ratios similar to those of the full scale system. The objective of the test is threefold  

To assess the ability of the continuous mixer to dampen feeder-related fluctuations or variance in composition. 

To determine the residence time distribution of the components in the mixer. 

The mixer operating conditions must be selected carefully based on kinematic and dynamic similarity conditions. The following experimental considerations must be heeded
