There are several reasons for the material not discharged from outlet or discharge slowly:
1. The outlet level is higher than the screen surface, the material will stay rotating on the screen surface or accumulate at the gate of outlet. Generally it should be slightly lower than the screen surface or at the same level as the screen surface as per the material density or the impurity content.
2. The machine should place on the level ground, other wise, it will not only make the material no discharged from outlet, but also damage the screen mesh.
3. Non matched screen mesh or aperture size
4. The screen mesh is too loose, need tight the screen
5. The important reason is angle of the motor hammer is not proper. Generally, the angle of the motor is 45 degrees setting in factory. It can be adjusted slowly according to the actual usage. The angle is small, the material spreads out quickly, the angle is large, the material generally gathers toward the center or discharges slowly.
6. If it is a double-layer or more layer rotary vibrating screen, the lower layer is discharged and the upper layer cannot be discharged. In addition to the angle adjustment of the motor, another reason is that the motor power of the rotary vibrating screen is small so insufficient to drive the machine.
Note: There will be a motor rotating direction mark on the machine base, the motor is rotating in anti clock way, it is work in clock way, it also result in material no discharge.
