How to solve the problem that the screening output of vibrating screen becomes smaller?

During the screening process of the ultrasonic vibrating screen, the movement track of the materials on the mesh surface is relatively disordered, either gathering in the middle or dispersing around. Why did this happen?

The materials screened by the ultrasonic vibro sieveing system gather in the middle, which indicates that the force of the vibrating motor becomes small and the materials cannot move. The force of the vibration motor is reduced, which means that the angle of the upper and lower eccentric blocks of the vibration motor is increased. It is OK to reduce the included angle. If the materials are scattered around, it means that the force of the vibration motor is increased, the material movement route is too long, and the force of the vibration motor is increased. It means that the angle of the upper and lower eccentric blocks of the vibration motor is reduced, and the included angle can be adjusted.

The screening of ultrasonic vibrating sieving system is mainly used for screening various loose materials such as powder, granular and small pieces. It is not suitable for screening special materials that are easy to deteriorate, sticky, easy to agglomerate or high temperature, afraid of pressure and corrosive. During the screening process of the ultrasonic vibrating screen, the material movement is disordered. When the vibrating motor is biased fast and does not move, the screen is not tight and loose. There are many grooves on the screen surface. Take down the outer ring and tighten it. When the vibrating motor is biased fast and the screen is tight, the ground of the vibrating screen is uneven, and the ultrasonic vibrating screen can be placed flat. It may also be caused by the unstable mode of material delivery. If the material delivery is stable.
