How does a sieving machine work?

A sieving machine operates by using vibration or oscillation to separate particles based on size. The machine consists of a vibrating screen or mesh that allows smaller particles to pass through while larger particles are retained on the screen surface. As the machine is turned on, a vibrating motor or other mechanism generates vibration or oscillation, causing the screen to move rapidly. This movement agitates the particles on the screen, allowing smaller particles to pass through the openings in the mesh, while larger particles are retained. The sieving process can be further enhanced by adjusting the amplitude and frequency of the vibrations to optimize separation efficiency. The separated fractions can then be collected and analyzed for particle size distribution or further processing.
