Summary
This chapter provides a review of mechanical design of mixing equipment for the chemical engineer who needs to communicate with mechanical engineering colleagues. The diversity of mixer applications requires many variations of standard and special equipment components. Different combinations of mixer power, impeller size, rotational speed, and shaft length make the mechanical design of most mixers unique. Beyond the process requirements, a mixer must be designed mechanically to handle hydraulic forces within material limitations. Proper mechanical design involves both the selection of appropriate components, such as motors, shaft seals, and impellers, and the sizing of components, such as speed reducers, shafts, and supports. Process requirements and operating conditions can be interpreted as mechanical loads. Engineering design methods interpret those loads for the proper mechanical design of mixer components. These issues are reviewed and explained with detailed illustrations of the key components and design issues.
