Ultra high speed colloid mill is a mechanical device used for fine processing of fluid materials. It combines various mechanical properties such as homogenizers, ball mills, three roll machines, shearing machines, mixers, etc., and has the functions of ultrafine grinding, dispersion emulsification, homogenization, mixing, etc. After processing, the material has a particle size of 2-50 microns and a homogeneity of over 90%, making it an ideal equipment for ultrafine particle processing.

What are the advantages of a high-speed and high shear colloid mill compared to a regular colloid mill?

① Working chamber mode

Domestic equipment: horizontal or vertical (motor integrated), bearing parts are subjected to high stress, easy to damage, complex maintenance, and difficult cleaning

Vertical, belt driven, easy to maintain, can effectively protect the motor and gearbox, prevent damage in accordance with fluid flow principles, easy to clean

② Speed:

Domestic equipment: Currently, it is not regulated through frequency converters. If regulated through frequency converters, their bearings cannot withstand high-speed operation. Usually at 3000 RPM (this is determined by the internal structure and precision of the colloid mill). )

We can adjust the speed through frequency conversion, which can reach 7890/13789RPM. By accelerating with a belt, our bearings can withstand 140000RPM (3-4 times their speed and 3-4 times their grinding force, resulting in smaller grinding fineness)

③ Sealing form

Domestic equipment: single mechanical seal or shaft seal, high leakage failure rate, product leakage into the motor, causing motor burnout

Double mechanical seal, easy to clean, reduces leakage to * * * low, can operate continuously for 24 hours

④ Linear velocity (such as the same diameter of the grinding head):

Domestic equipment: approximately 10-15m/s

Can reach 23-40m/s

⑤ Module Head:

Domestic equipment: There is only one type of module head.

Six different module heads can be selected to achieve multiple functions, such as three-stage emulsification module, ultra high speed module, XM colloid module, XMD colloid module, batch powder liquid mixing module, and continuous powder liquid mixing module.

⑥ Structure of grinding head

Domestic equipment: The groove depth of each grinding head of the helical teeth is the same, and the flow channel volume is the same.

The structure of the groove is inclined teeth, and the groove depth of each grinding head is different, and the volume of the flow channel of the inclined teeth is from top to bottom.

This creates a fundamental difference, as we can ensure that the material is continuously ground from top to bottom, while they can only achieve a grinding effect from one grinding head to another.

⑦ Third level structure:

Although they are all three-level structures

Domestic equipment: The groove is a straight line, and the depth of grooves in the same level is the same.

The groove is a curve with varying depths, with the top being deeper and the bottom being shallower.

⑧ Product Effect

Domestic equipment: Limited particle size and fineness, difficult to achieve below 100 microns, and poor repeatability.
