Brief Introduction of Circular Vibrating Screen

The circular vibrating screen is sieving equipment that can be used for classifying, dehydrating, desilting, disintegrating, and sorting. The main function of the vibrating machine is to screen and sort material through the vibration of the sieve body. The screening process is not only important to improve the value of products after but has a direct effect on the next mining operation ...Learn More
