Rotary Vibrating Sieve, also known as vibro screen, vibro sieve, vibro separator. Vibro sifters are involved in ceramic, coating, papermaking, chemical, food & beverage, glass, abrasive, pharmaceutical, mining and other industries. Features: 1. Superior accurate separation efficiency 2. Lower noise levels 3. Ball tray for anti-blinding 4. Multi deck models available 5. Upper deck open or covered 6. Explosion-proof motors if required Working Principle: Rotary Vibrating Sieve are driven by vertically mounted vibration motor having eccentric weight at the top & bottom end of the shaft. At the time of Motor rotation top weight causes vibration in horizontal plane whereas the rotation of bottom weight causes tilt & vibrations in vertical plane. By changing their lead angle, various spiral-screening patterns are obtained to suit different application.Buy Gyratory Vibrating Screen website:http://www.yrscreen.com/fine-screening-equipment/gyratory-vibrating-screen/
