Noiseless Type Vibro Sifter is a circular gyratory screen used for separating mass composition of solids, liquid from solid and for gradation of materials as per particle sizes. The Vibro Sifter has robust construction, smooth operation and requires low maintenance. The Vibro Sifter ensures that the vibration is generated in three different planes along the vertical axis by means of a designed vibratory motor having off centred weights at the top and bottom end of the motor shaft and the angle of lead of the lower weight to the upper weight provide variable screening pattern and output. The Noiseless Type Vibro Sifter has easy to dismantle for cleaning screens and is noiseless, maintenance free.
