Vibrating Screen : How to adjust rotary vibrating screen eccentric block?

1. Adjust the eccentric block phase angle (the upper and lower eccentric block vertical stagger angle),which can change the material movement and residence time on the screen cloth. In order to make the screen machine meet the demand of separation status for various materials, such as material distribution, hourly output, screening efficiency, screening percentage changes, we need to adjust the eccentric block angle to the best condition.

2.For unchangeable angle of rotary vibrating screen, open the barrels bottom adjusting aperture, loosen fixed bolt of the lower eccentric block, adjust the phase angle of upper and lower weight in the opposite direction according to the required screening materials movement. Then put a small amount of material on the screen cloth and make the machine run. When you are checking the screen surface materials trajectory, if processing parameters all reach the best effect, stop the screen and tighten the bolt, adjustment is finished(Please be sure to tighten the bolt well).

3.Additional eccentric block adjustment. There are additional heavy weights on the side of upper and lower eccentric blocks,the main effect is to increase the output vibration force of rotary vibrating screen, you can increase and reduce the exciting force according to the different screen layer numbers and different material proportion which will make the screen reach the best sieving effect.
