Vibro Sifter - Lab Vibro Sifter Machine


Vibro Separator

is, also known as Vibro Sifter and the machine used for laboratory purpose is known as Lab Vibro Sifter. It is a circular unitary gyratory screens that are widely used for various applications such as the separate mass composition of solids from solids, liquid from solid and for gradation of materials as per particle size. To achieve this, screens are vibrated in three different planes beside the vertical axis. It uses the vibratory motor that has off-centered weights at the top and bottom ends of the motor shaft to execute it.

Vibration is created in the horizontal plane by the top weights. This leads to the movement of material across the screen in the direction of the periphery. Similarly, vibration is created in the vertical tangential axis by lower weight. The variable control of the screening pattern is provided by the angle of the lead of lower weight in connection to the upper weight. It helps in material movement across the screen including a vertical plane and tangential plane leading to maximum screening. As a leading manufacturer of Vibro Separator, we offer high tech Vibro Sifters in a wide range of screen size options.

The Vibro Sifter Unit is equipped with high performance vibratory motor to run on 400/440V, suitable HP, 3 phase, 50 cycles electric supply, with adjustable eccentric weights on the top and bottom of the motor shafts that are vertically mounted at the center of the base plate of the screening unit. Screening unit of this advanced Vibro Sifter comes with Stainless Steel 304 screen that is inserted between Stainless Steel 304 bowl and hopper using special clam with gasket, which in turn is clamped to the base plate. Rugged Springs positioned over the circular motor base increases the vibration and also restricts the transfer of vibration to the floor.
