Different sieve sizes can be described by numbers such as 200 mm, 75 \u03bcm, and 200 mesh. They may all look like they describe the \u201csize\u201d of a sieve, but they do not refer to the same thing. What do these numbers mean, and how should you read them?<\/p>\n\n\n\n

Once you understand what each of these numbers means, they are much easier to tell apart.<\/p>\n\n\n\n

What Do 200 mm, 75 \u03bcm, and 200 Mesh Mean?<\/h2>\n\n\n\n

Sieve specifications often include numbers such as 200 mm, 75 \u03bcm, and 200 mesh. They refer to different specifications:<\/p>\n\n\n\n

Number<\/strong><\/td>What it means<\/strong><\/td><\/tr>
200 mm<\/td>Sieve frame diameter<\/td><\/tr>
75 \u03bcm<\/td>Sieve opening size<\/td><\/tr>
200 mesh<\/td>Mesh count<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n


200 mm refers to the size of the sieve frame, 75 \u03bcm refers to the size of the sieve openings, and 200 mesh refers to the mesh specification. They are related, but they are not the same thing.<\/p>\n\n\n\n

\"200<\/figure>\n\n\n\n

For example, a 200 mm sieve frame can be fitted with screens with different opening sizes. A 200-mesh sieve, on the other hand, does not have 200 \u03bcm openings. A common 200-mesh sieve has an opening size of about 75 \u03bcm. For more details on standard sieve frame diameters, aperture sizes, and mesh specifications, see our guide to Standard Sieve Sizes.<\/a><\/mark><\/strong><\/p>\n\n\n\n

What Are the Different Sieve Sizes for Different Applications?<\/h2>\n\n\n\n

The sieve size depends on the application and the amount of material to be screened. Small amounts of material can be handled with a small hand sieve, standard test sieves can be used for particle size testing, and production lines with continuous screening require industrial screening equipment.<\/p>\n\n\n\n

Small Hand Sieves<\/h3>\n\n\n\n

If you only need to screen a small amount of powder, granules, or other materials, a small hand sieve can be used. These sieves are compact and easy to use, making them suitable for small-scale manual screening.<\/p>\n\n\n
