1. The voltage of power supply voltage is insufficient. If the circuit is not connected as required, the voltage is insufficient, which will cause the vibration amplitude of the vibrating screen to be smaller. 2. Too few eccentric blocks. Try increasing the number of eccentric blocks to increase the amplitude. 3.
