WORKING

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 turnover 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.

VIBRO SIFTER SCREEN

Vibro separators are circular gyratory screens used 60mesh size 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 centre of top screen. The undersize material passes rapidly through the screen during its travel to the periphery. The oversize material get continuously discharged through a tangential outlet. This is achieved by specially designed Vibratory Motor (Good earth make motor) along with eccentric Top and Bottom Weights. Having all contact parts are S.S. 316 quality & non - contact parts are S.S.304 quality or cladded with S.S. 304 quality.

CONSTRUCTION AND FUNCTION

Vibro Screens are designed on the principle of gyratory motion generated by double eccentric weight mounted on two ends of the shaft of vertically mounted specially designed vibratory motor. The screening assembly consisting of one or more set of Deck/screens is mounted on a set of annularly located springs, effectively isolating the base from vibrating assembly.
The double weight moving with the shafts and located at relative angular position produces three dimensional vibrations which in turn cause the material falling on the screen mesh move at a specific speed in straight to spiral direction giving controlled and effective screening.
Due to the adjustability of weight and the relative angle between them it is possible to make the material move on the screen in desired path to achieve the desired retention time for effective screening before the material gets discharged from the outlet spout. During this process the particles smaller than the mesh aperture fall through the mesh and the oversize material gets discharged from the outlet spout. This process is repeated on the next mesh in case of multi deck screening.

BALL TRAY / RING TRAY

This is useful to achieve non clog screening. A tray having rubber /PP balls or rubber / plastic rings is mounted underneath the fine mesh screen. The ball / ring get continuous vibrations from machine and hence they jump and hit the fine mesh from below. This makes particles trapped in the mesh holes to fall down and thereby keep mesh opening as clear as possible.

KEY FEATURES OF VIBRO SIFTER

Circular Vibrating Screen Separators, also known as vibratory screeners or vibrating screens, are used for the separation, classification, and dewatering of materials based on particle size. Here are some key features of vibratory screening machines :

Vibratory Motion : Vibrating Screen Separators utilize an oscillating motion generated by a vibratory motor or eccentric weights to impart vibrations to the screen mesh. This motion helps in efficient screening and separation of materials.

Adjustable Vibration Parameters : The vibration parameters, such as frequency, amplitude, and angle of inclination, are adjustable in Vibrating Screen Separators. This adjustability allows operators to optimize the machine's performance based on the specific characteristics of the material being screened.

Versatile Screen Media : Vibrating Screen Separators can be equipped with a variety of screen media options, such as wire mesh, perforated plates, or synthetic meshes. This allows for customization based on the application and material requirements.
