Impeller is the key component of mechanical mixing equipment.In the mechanical engineering design of mixing equipment, the selection of the impeller type is very important.When selecting the type of the impeller,it is necessaryto make a comprehensive evaluation of the process,equipment,mixing requirements,economy,etc.and find out the main control factors of the operation,combine the performance characteristics and flow state of impeller,select the appropriate impeller.

Flow state:The horizontal circumferential flow is dominant at low speed,the radial flow at high speed,and the up and down circulation with baffle.
