Dewatering screen is LZZG patent product. It adopts dual-motor self-synchronization technology. The motors coordinate with universal eccentric and adjustable amplitude vibrator. When the two motors start to work, the vibrators move reversely at the same time. The centrifugal force is generated by the eccentric blocks superpose themselves and form a single direction vibration. The high frequency vibration drives the screen move back and forth in line repeatedly. So the sand will be dehydrated and filtered. Now it is widely used in crushed sand plant, natural sand washing plant, coal mining screening plant and mineral tailings screening site,etc.
