The working principle of the small mixer is: a mixing head with multiple interactive mixing blades. The mixing head can be directly placed on the ground for high-speed rotation. At the same time, the equipment can be controlled by hand to move 360 degrees at any angle and distance, so as to realize three-dimensional high-speed three-dimensional mixing.

小型搅拌机搅拌速度是由多个参数决定的：轴功率（P）、 桨叶排料量（Q）、压头（H）、桨叶直径（D）及搅拌转速（N）是描述一台搅拌机的五个基本参数。桨叶的排料量与桨叶本身的流量准数，桨叶转速的一次方及桨叶直径的三次方成正比。而搅拌消耗的轴功率则与流体比重，桨叶本身的功率准数，转速的三次方及桨叶直径的五次方成正比。

The mixing speed of small mixer is determined by several parameters: shaft power (P), blade discharge (q), head (H), blade diameter (d) and mixing speed (n) are the five basic parameters to describe a mixer. The discharge of the blade is directly proportional to the flow standard of the blade itself, the first power of the blade speed and the third power of the blade diameter. The shaft power consumed by stirring is directly proportional to the specific gravity of the fluid, the power criterion of the blade itself, the third power of the rotating speed and the fifth power of the blade diameter.

在一定功率及桨叶形式情况下，桨叶排料量（Q）以及压头（H）可以通过改变桨叶的直径（D）和转速（N）的匹配来调节，即大直径桨叶配以低转速（保证轴功率不变）的 搅拌机产生较高的流动作用和较低的压头，而小直径桨叶配以高转速则产生较高的压头和较低的流动作用。

Under the condition of certain power and blade form, the discharge (q) and head (H) of the blade can be adjusted by changing the matching of the diameter (d) and speed (n) of the blade, that is, the large diameter blade is equipped with low speed (ensuring the shaft power is unchanged) The mixer produces higher flow effect and lower head, while the small diameter blade with high speed produces higher head and lower flow effect.

在搅拌过程中，要使微团相互碰撞，的办法是提供足够的剪切速率。从搅拌机理看，正是由于流体速度差的存在，才使流体各层之间相互混合，因此，凡搅拌过程总是涉及到流体剪切速率。

In the mixing process, the only way to make the micro clusters collide with each other is to provide enough shear rate. From the view of stirring mechanism, it is because of the existence of fluid velocity difference that the fluid layers are mixed with each other. Therefore, the shear rate of fluid is always involved in the mixing process.

剪切应力是一种力，是搅拌应用中气泡分散和液滴破碎等的真正原因。必须指出的是，整个搅拌过程中，流体各点剪切速率的大小并不是一致的。通过对剪切速率分布的研究表明，在一个搅拌过程中少存在四种剪切速率数值。

Shear stress is a kind of force, which is the real cause of bubble dispersion and droplet breakup in stirring applications. It must be pointed out that the shear rate at each point of the fluid is not the same throughout the mixing process. The results show that there are at least four shear rate values in a stirring process.

研究表明，就桨叶区而言，无论何种浆型，当桨叶直径一定时，剪切速率和平均剪切速率都随转速的提高而增加。但当转速一定时，剪切速率和平均剪切速率与桨叶直径的关系与浆型有关。当转速一定时，径向型桨叶剪切速率随桨叶直径的增加而增加，而平均剪切速率与桨叶直径大小无关。

The results show that the maximum shear rate and average shear rate increase with the increase of rotating speed, regardless of the size of the blade. However, when the rotating speed is constant, the relationship between the maximum shear rate and the average shear rate and the blade diameter is related to the pulp shape. When the rotating speed is constant, the maximum shear rate of radial blade increases with the increase of blade diameter, but the average shear rate has nothing to do with the blade diameter.
