Gyratory motion is the most effective method for screening. It causes 100% rotary motion and causes dispersion stirring & stratification of material to be sifted. Feed material constantly flows in Horizontal motion along a loop pattern on Vibro screen surface. GREENFIELD Vibro screen provides optimum screening & assures maximum feed-rate & efficiency.
Vibro screen are driven by a special type of vertically mounted motor having eccentric at the upper & lower end of the shaft. Rotation of out of balance top weight causes vibration in Horizontal plane whereas the rotation of lower weight causes tilt & vibrations in vertical plane.
The heart of the Vibro screen is its special heavy duty, Robust Motor, having out of balance weight at top & bottom. By changing their lead angle, various spiral-creening patterns are obtained to suit different application.
