A. Conversion of vibrating sieve mesh size to sieve hole size on the screen: The theory of Tyler standard screen scale is based on 200 mesh sieve size with 0.074mm sieve hole size. So for 100 mesh size, the sieve hole size is 200 * 0.074mm ÷ 100 = 0.148mm And for 325 mesh size, the size hole size is 200 * 0.074mm ÷ 325 = 0.045mm. B.

Arrange the standard sets of sieves from top to bottom in the order of decreasing sieve holes. The bottom layer is set with a sieve bottom, so don't mess up the order. Pour the weighed sample into the top sieve, and then cover the sieve cover. Install the sieve on the vibrating screen machine, and then vibrate for 10~15 minutes.
For example, the 2.0mm(0.0787 inches) sieve is perfect for wheat, and the 2.25mm (0.0886 inches) for barley. In the food industry, sieve sizes range from 25mm to 0.6 mm(0.984 to 0.0236 inches). For example, flour-milling companies use sieves of increasing apertures to remove particles from flour. Examples

Once the application requirements are clear, a suitable mill can be selected. To facilitate this process, Retsch displays the strength and efficiency of each ball mill model in a spider-net diagram, see Figure 3. A planetary ball mill, for example, offers a big jar volume compared to a mixer mill and shows a high value on this diagonal.
Whilst the knife side mills sticky products, the hammer side is used for crushing hard, crystalline products. The particle size in a hammer mill is determined by the sieve size chosen for the mill.
