Ultrasonic vibro sifter is based on the original motor to drive the vibro sifter to vibrate, adding ultrasonic. The problem of vibro sifter blocking the screen is the key to restricting the screening efficiency. The blocking problem solves the problem of fine powder materials below 600 mesh. The sub-accuracy can reach 1-100%.
Ultrasonic vibro sifterr is a kind of vibration wave greater than 20000 Hz. In ultrasonic vibro sifter, we generally use the frequency band between 30000-40000 Hz. Its vibration characteristics are: under a small amplitude, the mesh produces a sinusoidal longitudinal transmission sound wave with a strong penetrating ability and greater than 20,000 times, bounces off the material adhering to the screen, so as to prevent the material from blocking the screen.
Ultrasonic vibro sifter improves the leveling of low-density powder in gravity sedimentation (light contact between the powder and the mesh), slip effect, improves the retention or wedging of high-density metal in the mesh, and improves the adhesion effect of electrostatic powder. Thereby improving the screening efficiency and screening quality. It is expressed by the sieving pass rate, which generally increases the pass rate by 50%-400% compared with no ultrasonic vibro sifter.
