Discussion on the rotational speed of JJ-2 tissue crushing homogenizer
Date: 2018-01-16Read: 1

  JJ-2 tissue crushing homogenizerRotating speed *, the material in the glass is simultaneously split, crushed, mixed and other processes driven by a motor to rotate the rotary blade, stirring and crushing the material. This machine has a small volume, low power consumption, and high work efficiency, but it is not suitable for high viscosity liquid homogeneous materials with hard physical properties.

JJ-2 tissue crushing homogenizer is suitable for scientific research, medical treatment, chemical pharmaceuticals, biological manufacturing products, food industry and other fields. At the same time, it plays an important role in industrial equipment mixing systems, especially in solid-liquid mixing, liquid-liquid mixing, oil-water emulsification, dispersion homogenization, and shear grinding, which have extremely important applications.
  JJ-2 tissue crushing homogenizerIs the stirring speed commonly referred to as the shear speed? Those who have studied high school physics know that speed is divided into angular velocity and linear velocity. Shear velocity naturally refers to linear velocity, which is equal to angular velocity multiplied by diameter multiplied by π. Therefore, why is the speed of industrial homogenizers generally only 3000rpm or 1500rpm, while JJ-2 tissue crushing homogenizers have a high speed of 10000rpm or 280000rpm? It is because the diameter factor is taken into account, so that the shear linear velocity of the two is close, and the final effect is also close.
From another perspective, the characteristic of laboratory experiments is that the quantity is small, so the physical size of the rotor must adapt to the corresponding small amount, and the diameter must be small. In order to compensate for the negative impact of small diameter on linear velocity, it is necessary to increase the angular velocity of the rotor, thus forming the high-speed of the experimental instrument. From the above, it can be seen that,JJ-2 tissue crushing homogenizerThe rotational speed should be considered in conjunction with the actual processing capacity.
