VIBRO SIFTER

Vibro Sifter works on gyro principle. The required gyratory motion is obtained from specially designed gyro motor, which is fitted underneath the vibrating assembly. The complete vibrating assembly is isolated from the base by means of specially designed rugged springs. Gyro-motor is fitted with top & bottom eccentric weights designed as per required centrifugal force. This whole assembly is covered by SS plate. The deck hopper is fabricated from SS 316 sheet. To collect the discharge tangential, discharge port is provided on the hopper.

Conical shape top lid is provided with charging port. Screen is fitted in between the hopper & top lid. The machine inner & outer surfaces are mirror polished.

CONSTRUTION AND OPERATION :

Vibro separators are circular unitary gyratory screens used to separate mass composition of solids from solids. Liquids from solid and for gradation of materials as per particle size, having a very wide range of applications. This is accomplished by vibrating the screens in three different planes along the vertical axis by means of a specially designed vibratory motor having off centered weights at the top and bottom end of the motor shaft. The top weight causes vibration in the horizontal plane which causes the material to move across the screen towards the periphery. The lower weight acts to tilt the machine which causes vibration in the vertical tangential axis . The angle of lead of the lower weight with relation to the upper weight provides variable control of the screening pattern. Thus the material moves across the screens and also in the vertical and tangential planes enabling maximum screening. Vibrosifter are available with a wide range of possible screen sizes (mesh) option for multiple deck separation is also possible.

The unit consist of specially designed vibratory motor to run on 400/440V , HP, 3 phase, 50 cycles electric supply, with adjustable eccentric weights at the top and bottom of the motor shafts mounted vertically at the center of the base plate of screening unit. Screening unit consists of SS 304 screen sandwiched between SS 304 hopper and bowl with the help of special clamp with gasket. This in turn is clamped to the base plate. Rugged springs placed over the circular motor base amplify the vibration and at the same time restrict the vibration from being transferred to the floor.
