The whole process includes:

• Pour the materials to be processed into the vibratory sifter through the feed port.
• According to different screening requirements, the materials will pass through sieves with different mesh sizes from 1 to 5 layers.
• The vibratory sifter continuously makes the materials pass through the sieve holes of different meshes in a circular motion on the sieve with decreasing mesh size.
• During this process, the bouncing balls under each layer of sieves will continuously hit the sieves, allowing the materials to be fully screened and effectively preventing the materials from clogging the screen holes.
• Materials close to the screen holes can also be fully screened through the sieve.
• Materials located below the screen that are larger than the screen aperture are discharged from the discharge port of this layer, completing the purpose of screening or filtering.
