The macromixing times of four types of combined agitators(orthogonal twi-stratum triangle blade with single ribbon or wit inner/outer ribbon,anchor type blade with three-blade impeller or with inner/outer ribbon)were determined by temperature measurement method,with carboxymethyl cellulose solution as experimental media in the concentration of 1%,2%,3% and 3.

This fact could be attributed to the interaction of micromixing and macromixing and was vital to industries such as the manufacturing of ultra-fine parti.

The mathematic model has been developed for macromixing and micromixing in the fading process, and the model parameters for three kinds of impellers are given.
