The structure of the standard screen, the screen frame should be flat and smooth, and it should be convenient to nest with other screens, covers, receiving trays, etc. of the same basic size of the screen frame, and the connection between the wire mesh and the screen frame should prevent the street screen from Leakage of sub-materials.

Mark of  Standard Test Sieve: There should be a clear metal nameplate fixed on the screen frame, and the nameplate should have the following contents:

1. The basic size of mesh and wire diameter;

2. Implementation standards;

3. The material of wire and screen frame;

4. The name and logo of the manufacturing company.

The so-called mesh number of the  Standard Test Sieve refers to the particle size or thickness of the material. The general definition refers to the sieve within the area of 1 inch * 1 inch. The material can pass through the sieve, and the number of holes in the sieve is defined as the mesh. For example, 200 mesh means that the material can pass through a screen with 200 meshes within 1 inch*1 inch. By analogy, the larger the mesh number, the finer the particle size of the material; the smaller the mesh number, the larger the particle size of the material. The sieving particle size is the size of the sieve holes that the particles can pass through the sieve, expressed as the number of sieve holes in a 1-inch (25.4mm) wide sieve, so it is called the mesh number.
