In the actual production process, due to the actual factors such as the characteristics of the material, the vibrating screen may have a material movement trajectory concentrated in the middle or the edge, unable to fill the screen surface, resulting in low screening efficiency or blocking the net. Therefore, it is necessary to understand how to change the trajectory of the material on the vibrating screen with a small adjustment.
3 ways to change the trajectory of material on the vibrating screen
1. Change the phase angle of the upper and lower weights to change the movement track and residence time of the material on the screen. In order to adapt the sieve machine to the separation state required for various materials, such as material distribution, throughput, separation efficiency, and over-network rate, it should be adjusted to the ideal state.
2. The hammer on the vibrating screen should not be adjusted. Open the bottom barrel adjustment hole and loosen the lower weight fixing bolt. According to the trajectory of the sieved material, adjust the phase angle of the upper and lower weights in the opposite direction to the discharge port. Then, a small amount of material is placed on the screen surface to make the sieve machine run, and the trajectory of the sieve material is checked. If the processing parameters reach the desired effect, the bolts are tightened and the adjustment is finished (remember to tighten the fixing bolts).
Note: Sometimes due to the influence of parameters such as specific gravity, humidity, stacking inclination angle, etc., it is impossible to adjust the phase angle once, so the user should have sufficient patience to adjust and make the sieve machine play its high efficiency.
Vibrating screen upper and lower weight adjustment method
3. Adjustment of additional weights. An additional weight is placed on one side of the upper and lower weights, and its function is to increase the exciting force of the screening machine. According to the number of layers of the user's sieve machine and the specific gravity of the material, the exciting force is increased or decreased, and the number of additional weights is increased or decreased. It can make the sieve machine achieve the desired screening effect.
