A contra-rotating impeller design potentially eliminates the need for baffles. The contra-rotating impellers design consists of two impellers rotating in opposite directions about the same axis. Two impellers are arranged one behind the other, and the power is transferred from the motor via bevel gear, planetary gear, or spur gear transmission ...

Superior Quality Sand Making and Reshaping Equipment. V-SIC series vertical shaft impact crusher adopts an advanced impeller with four-port deep cavity, unique dust-proof and sealed bearing cylinder, efficient "rock on rock" and "rock on iron" crushing cavity, the anti-jam and wear-proof main body and other latest technology achievement.
This paper assesses the influence of various SGS models that are suitable for predicting rotating stall in a low-specific speed centrifugal pump impeller.
The impeller is the central rotating component of a centrifugal pump, responsible for creating the fluid flow. The speed at which the impeller rotates directly affects the volume and pressure of the fluid flow. In general, an increase in impeller speed will increase the pump's flow rate and pressure output. However, this relationship is not ...

As the rotating impeller penetrates into the particle bed, the transient vertical force F b and rotating torque T b on the blade are recorded. In FT4 rheometer, the total input mechanical work E is calculated for the torque and downward force: (21) E = ∫ 0 H T b R tan α + F b dH where R is the blade radius, i.e. D /2 in Fig. 1 .
