VIBRO SIFTER
 VILAS' Vibro separators are circular gyratory screens used
to separate solids from solids and liquid from solid. Vibro
Sifter consists of Specially Designed Motor mounted
vertically at the center of the base plate of the Screen.
The Screen is in between feeding hopper and bowl. The
material is fed on to the center of top screen. The
undersize material passes rapidly through the screen during
its travel to the periphery. The over size material get
continuously discharged through a tangential outlet. This is
achieved by specially designed Vibratory Motor along with
eccentric Top and Bottom Weights.
Working Principle -
The top weight on the motor shaft rotates in a plane close
to the centre of the mass of assembly. Rotation of the top
eccentric weights creates vibration in the horizontal plane
which causes material to move across the screen cloth to
periphery increasing the horizontal throw, causing oversize
material to discharge at a faster rate.
The bottom eccentric weight rotates below the centre of mass
creating tilt on the screen giving vibration in vertical and
tangential plane. Increasing the vertical component of
motion, this promotes turn over of material on the screen
surface helping maximum quantity of undersize material to
pass through the screen. Rugged Springs placed over the
circular motor base amplifies the vibration
Special Features of Vibro Sifter -
-
Faster Separation due to springs
-
Multi deck models available
-
Same sieve as used in Mechanical sifter.
-
Lesser Maintenance and Power Consumption than the
-
Conventional Sifter.
-
Simple & Compact construction.
