Lead powder in the industrial area have wide using scope, but not easy to sieve. Small particle size of lead powder is easy to agglomerate and has adsorption, when through vibration screen to sieve lead powder, easy to block screen mesh, reduce screening rate, and seriously affect the screening efficiency and screening accuracy of vibration screen. Therefore, for this situation, we recommend customers to use ultrasonic vibration screen. The sieve machine is by ultrasonic system to change the electric energy into mechanical energy, and transmitted to the mesh, subjects ultra-fine powders to huge ultrasonic acceleration, thus prevent the adhesion, friction, leveling and other blocking mesh factors, improve the screening efficiency and cleaning screen efficiency.
