Shanghai Shibang vibrating screen moves round, has multilayers and is high efficient. The vibratory screen adopts the barrel type of eccentric shaft vibration exciter and eccentric block to adjust the swing. The screen is of the flowing characteristics, the screening line is long and specification of materials screened is various, and it is also of reliable structure, strong exciting force, high screening efficiency, low vibrating noise, long durability, convenient maintenance, safe operation, etc. It adjust the ampitude by tub-shaped violent vibration screen of eccentric shaft and eccentric blocks. The body moves like a circle, in order to make the materials screened
