This Y series vibrating screen is vibrated by the circling motion. It is high efficient screen for filter materials into multiple grade according to the gravel size. For the compact structure and the convenience installation, it is the ideal screening device for prefilter of the feed materials before the primary crushing in the quarry site, it also can be used as separation and filtration solely. The vibrating screen adopts cylinder type eccentric shaft vibrator and partial block to adjust the amplitude. The materiel sieve drip line is long and more sieving specifications. Features 1.Cylinder-type eccentric shaft and eccentric block to make strong vibrating force. 2.Long material screening line, various sieving specifications. 3.Simple structure, reliable operation, low noise, low power consumption. 4.High screening efficiency, large capacity, less block. 5.Sealed structure available to protect the dust pollution. 6.Adjustable amplitude by changing the weight of the eccentric block.
