Since part of the work of the rocking machine is a fine operation, it is impossible to avoid such problems during operation. Sometimes, when the material is screened, the discharge condition is different. At this time, the material sieve can be adjusted by adjusting the upper and lower weights. Points, in order to achieve better results.

First of all, we can adjust the additional weight of the rocking machine vibration motor, and install additional weights on one side of the upper and lower weights (upper and lower eccentric blocks), which can increase the vibration force of the vibrating screen, according to the proportion of the material to be sieved by the customer. Different from the number of selected vibrating screen layers, the excitation force is appropriately increased and decreased and the number of additional weights is adjusted. Secondly, the phase angle of the upper and lower weights of the vibrating motor can be changed, which changes the residence time and trajectory of the material on the vibrating screen.

Furthermore, the bottom barrel of the rocking machine vibrating screen can be opened, and the fixing bolt of the lower weight can be loosened, and the phase of the upper and lower weights is adjusted in the opposite direction of the vibrating screen discharge port according to the movement track of the material sieved by the vibrating screen. angle. Then, the material is placed on the vibrating screen and the vibrating screen is energized to see the movement track of the material on the screen surface. If the material separation efficiency, permeable rate, and treatment amount, the distribution of the material on the screen surface is relatively uniform, and the fixing bolt can be tightened and then tightened.
