The mixer is determined by several parameters, using any single parameter to describe a mixer is impossible. The shaft power (P), the drainage volume (Q), head (H), blade diameter (D) and stirring speed (N) are the five basic parameters describing a mixer. Drainage amount and blade itself the flow number, blade speed of a side and the blade diameter of three Fang Cheng. The stirring shaft power consumption and the proportion of fluid, power blade itself number, speed of three times and five times the diameter of the blade is proportional to the square. In a certain power and blade form case, blade discharge rate (Q) and head (H) by changing the blade diameter (D) and speed (N), to adjust, namely large diameter blades with low speed (to ensure that the shaft power constant) flow of the mixer generates high pressure and the head is low, head and small diameter blade with high speed is high and low flow. In the stirred tank, to make micelles collide with each other, the only way is to provide adequate shear rate. From the mixing mechanism, it is because of the difference of the fluid velocity, the fluid mixing between the layers, so that the mixing process always involves fluid shear rate. Shear stress is a force, is the real reason for mixing application of bubble dispersion and drop breakup etc.. It must be pointed out that the fluid in the stirred tank by the magnitude of the shear rate is not consistent. The study shows that the shear rate distribution, there are at least four kinds of shear rate values in a stirred tank are: experimental study shows that on the blade area, no matter what type of pulp, when the blade diameter, maximum shear rate and average shear rate with the speed increased. But when the speed is constant, the maximum shear rate and average shear rate and blade diameter relationship with slurry type. When the rotation speed is constant, the radial type blade maximum shear rate increased with the increase of the blade diameter, regardless of average shear rate and blade diameter. These Paddle Blade The concept of shear rate, zoom in and zoom in blender need special care in design. Because of the small groove compared with large slot, slot mixer has high speed (N), a small blade diameter (D) and low tip speed (ND) and other characteristics, and often has low speed slot mixer (N) large diameter blades (D) and high tip speed (ND) characteristics.
