Naku Industries Vibro screen (gyro screen) is Vibratory or Gyratory Sieving Machine designed on the principle of gyratory motion generated by vibro motor. Gyratory motion is the most effective method for screening. Vibro screen are driven by vertically mounted vibratory 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. “Naku” vibro screen provides optimum screening & assures maximum feed-rate & efficiency. Vibro screen is also known as gyro screen, vibrating screen, vibro sifter, vibro grader, rotary screen, etc…
