Do You Know How To Adjust The Mesh Size Of Colloid Mill?
Jun 19, 2025| Definition of mesh size
The mesh number of a colloid mill refers to the distance between the rotor and stator inside the colloid mill, usually expressed in numbers. The smaller the mesh number, the smaller the distance between the grinding grooves, the finer the particles are ground, but the friction between the grinding grooves will also increase, and the energy consumption will also increase.
Adjustment steps
Confirm the required mesh number: First, you need to clarify the required mesh number. Generally speaking, the smaller the mesh number, the finer the grinding, but the energy consumption will also increase. The required mesh number can be determined based on the product quality requirements and production capacity.
Open the colloid mill: Open the grinding disc, remove the grinding wheel, clean the inner wall of the grinding groove and the surface of the grinding wheel to ensure that there are no impurities affecting the adjustment.
Adjust the mesh number: Gently turn the adjustment screw by hand to gradually reduce the distance between the grinding wheel and the grinding groove until the required mesh number position is reached.
Test: After the adjustment is completed, certain tests are required. Samples can be used for testing, and the test results can be used to determine whether re-adjustment is required.

| GN-130 | 380/50HZ | 11 | 200-300 | 350 | 1000*500*1200 |
| GN-180 | 380/50HZ | 18.5 | 500-800 | 420 | 1050*550*1250 |
| GN-220 | 380/50HZ | 30 | 600-900 | 480 | 1080*600*1300 |
| GN-240 | 380/50HZ | 37/45 | 1000-1500 | 1300 | 1400*600*1350 |
| GN-300 | 380/50HZ | 75/90 | 3000-5000 | 1600 | 1500*700*1450 |
Notes
Before adjustment, it is necessary to confirm whether there are impurities inside the colloid mill, otherwise it will affect the adjustment result.
Pay attention to the strength when adjusting, and do not over-tighten the adjustment screw to avoid damage.
After adjustment, it is necessary to test to ensure that the quality meets the requirements.
Clean the colloid mill regularly to ensure the accuracy of the adjustment.
In short, the mesh adjustment of the colloid mill is a very important link and needs to be taken seriously. Only by adjusting the mesh correctly can product quality and production efficiency be guaranteed.
