Working Principle of The Mixing Machine

The mixer is determined by multiple parameters, and it is not possible to use any single parameter to describe a mixer. The axial power (P), (Q), D (H), and the mixing speed (N) are five basic parameters of a mixer. The discharge volume of the blade and the flow rate of the blade itself, and the speed of the blade and the diameter of the three Fang Cheng. While the shaft power consumption of the shaft power is proportional to the ratio of the fluid, the power of the blade itself is proportional to the five party and the diameter of the blade. In a certain power and blade form, the and Q (H) can be adjusted by changing the diameter (D) and rotation speed (N) of the mixer, which means that the large diameter blades with low rotation speed and low pressure head, while the smaller diameter blades with high speed, produce high pressure head and lower flow. In the stirred tank, the only way is to provide sufficient shear rate to make the micro clusters collide. From the mixing mechanism, it is because of the existence of fluid velocity difference, so that the fluid layers are mixed each other, therefore, where the mixing process is always related to fluid shear rate. The shear stress is a kind of force, which is the real reason for the dispersion of air bubbles and droplets in the application. It must be pointed out that the shear rate of the fluid in the stirred tank is not uniform. Through the study of the distribution of the shear rate, there are four kinds of shear rate values in a stirred tank. The experimental results show that the maximum shear rate and the average shear rate increase with the increase of the rotation speed of the blades. But when the speed is constant, the relationship between the maximum shear rate and the average shear rate and the diameter of the blades is related to the pulp type. When the speed is constant, the maximum shear rate increases with the increase of the diameter of the blade, and the average shear rate is independent of the diameter of the blade. The concept of blade shear rate is particularly careful in the reduction of the mixer and the design of the amplifier. Due to the small trough and trough compared to the, small mixer trough tend to have high speed (n), the blade diameter (d) and low tip speed (nd) and other characteristics, and trough mixer tend to have low speed (n) large blade diameter (d) and high tip speed (nd) and other characteristics.
