The difference between colloid mill and homogenizer

First of all: due to centrifugal movement, the flow is not constant, corresponding to the same viscosity of the material flow changes greatly. For example, the same equipment, colloid mill in dealing with viscous paint materials and thin dairy fluid, the flow can be a difference of more than 10 times;

Second: due to transfer between the stator and the material between the high-speed friction, it is easy to produce greater heat, so that the material was modified;

Third: the surface easier to wear, and wear, the refining effect will be significantly reduced.

However, the principle of homogenizer is the material in the mixing through the mixing of the blade, compression, folding, so that the mixture down to the bottom of the homogenizer, the material through the high-speed rotation of the homogenizer rotor and the stator between the strong Of the shear, shock, turbulence and a series of processes, was quickly broken into 200um-2um particles, due to the emulsifier in a vacuum state, the material in the mixing process of the bubble was timely pumping away.

Compared with the pressure homogenizer, colloid mill is first a centrifugal device, its advantages are simple structure, equipment maintenance and easy maintenance, colloid mill for higher viscosity materials and larger particles of materials. Its main shortcomings are also determined by its structure.
