The Mixing Equipment with a blade axis of rotation in the cylinder or tank, and a variety of raw materials, mixing, making it a mixture or device suitable consistency, widely used in coatings, inks, paints, adhesives and other chemical products production.

More extensive use of mixing equipment, and its development trends have also been more and more attention. At present, the mixing equipment obey the serialization and diversification, while also becoming a large scale.

PVC, ethylene, polyether, polybutadiene rubber and other devices, the use of stirred tank reactor volume has reached more than 70m3, the volume of the key equipment of China's domestic development of an annual output of 400,000 tons of PVC polymerization reactor has reached a 135m3, this Asia into the largest volume polymerizer other large-scale chemical industry production unit reactor volume is about 200m3, fermentation engineering, fermentation tank volume has been reached 350m3.

Large-scale mixing device has a lot of advantages: can improve product quality and uniformity, can reduce the footprint of the device, reducing the investment in plant construction, reduce device management and maintenance costs, and is also conducive to automated control.

The same time, large-scale process equipment for scientific research and design units with a higher demand, that is, how the results of basic research, relevant theory of unit operations with the requirements of the specific process of organic combine. For example: a large mixing equipment wall thickness is relatively thick, how better to solve heat transfer problems? Large mixing equipment, mixing shaft is generally longer, stirring bearing by torque, not only higher mixing equipment requirements, but also put forward higher requirements for the installation accuracy of the mixing equipment.
