Screen mesh number: The screen mesh number can also be directly converted into aperture, which refers to the length or width of the square mesh in the middle of the metal woven mesh. Currently, the range of single-layer metal wire woven mesh in China is 4 mesh-625 mesh. The larger the mesh number, the smaller the aperture.
The mesh number of the screen is also one of the important data of the vibration screening type. It can be said that without determining the mesh size, the entire vibration screen cannot be selected. At the same time, the mesh number of the screen and the characteristics of the material determine the cleaning method at the same time.
For example: for ore screening, if the customer needs a 5CM mesh, then a heavy-duty vibrating screen should be selected for screening. If the customer chooses a mesh between 3MM-0.1MM, then a square swing screen or a linear vibrating screen is the most appropriate.
If the customer needs to screen the mineral powder between 0.1MM-0.04MM, it is best to choose a rotary vibrating screen or a circular swing screen, because these two devices can add ultrasonic waves.
For example: for flour screening, the customer chooses a mesh size between 6-14 mesh, which is generally used for impurity screening, and the inline screen is the best choice. The customer chooses a mesh size of 40 mesh for general screening before bagging, and can choose between an inline screen and a rotary vibrating screen. If the customer chooses a mesh size of 60-80 mesh, which is generally used for making high-quality flour or high-end bread, then the rotary vibrating screen or circular shaking screen should be selected according to the output, and the inline screen is no longer suitable.
