Handbook of Industrial Mixing: Science and Practice,
edited by Edward L. Paul, Victor A. Atiemo-Obeng, and Suzanne M. Kresta
(John Wiley and Sons, Inc.,
2004) explains the differences, uses, and trade-offs among various mixers:
gear mixers, top entry mixers, side entry mixers, bottom entry mixers,
on-line mixers, and submerged mixers.
The book contains a CD-ROM with video clips showing the mixers in action
and details practical applications in key industries.
Most of the emphasis is on liquid mixing, but solid-liquid mixing and suspension is included.
