What is 20 Mesh in mm?
In the world of sieving and filtering, mesh size is an essential concept. Mesh size is a measure of the size of the openings between the threads of a mesh screen. It is usually measured in units of mesh, which is a count of the number of openings per linear inch. However, in some cases, it is more convenient to express mesh size in units of millimeters (mm). In this article, we will explore what 20 mesh in mm is and how it is used.
What is a Mesh?
A mesh is a grid of wires or fibers that are woven together to create a screening surface. The mesh size is determined by the number of wires or fibers per unit length. The higher the mesh size, the smaller the openings between the wires or fibers.
What is 20 Mesh?
20 mesh is a medium-coarse mesh size. It has 20 openings per linear inch, which means that the distance between each wire or fiber is approximately 0.841 mm. This mesh size is commonly used in various applications, including:
- Food processing: 20 mesh is often used to sift flour, sugar, and other dry ingredients in food processing.
- Pharmaceuticals: 20 mesh is used to filter powders and granules in pharmaceutical manufacturing.
- Chemicals: 20 mesh is used to filter chemicals and other materials in the chemical industry.
20 Mesh in mm
As mentioned earlier, 20 mesh has openings that are approximately 0.841 mm in size. This means that particles that are larger than 0.841 mm will be retained by the mesh, while particles that are smaller than 0.841 mm will pass through.
Conversion Chart
Here is a conversion chart for common mesh sizes to mm:
| Mesh Size | Opening Size (mm) |
|---|---|
| 10 mesh | 2.00 mm |
| 20 mesh | 0.841 mm |
| 30 mesh | 0.590 mm |
| 40 mesh | 0.420 mm |
| 50 mesh | 0.297 mm |
| 60 mesh | 0.250 mm |
Conclusion
In conclusion, 20 mesh in mm is a medium-coarse mesh size with openings that are approximately 0.841 mm in size. It is commonly used in various industries, including food processing, pharmaceuticals, and chemicals, to filter and sift powders and granules. By understanding the mesh size and its equivalent opening size in mm, you can choose the right mesh size for your specific application.
