Vibratory graders are circular gyratory screens used for performing the operation of Classification, Grading, Oversize/undersize Removal, De-dusting, De-watering, and any type of SIZE based separation. Machine 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 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 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
Special Features of Vibratory Grader –
Faster Separation of material
Lesser maintenance and power consumption
Simple & compact design
Multi Deck models are available.
Vibratory graders are widely used in chemical, pharma, food, paper industries, metallurgical - mining and in many other sectors etc. for spectrum of size based separation operations performed in most of the industry sector / applications due to its flexibility and distinctive advantages. Applications includes for performing the operation of Classification, Grading, Oversize/undersize Removal, De-dusting, De-watering, and any type of SIZE based separation.
Vibro Equipments offers the machines both in stainless steel (SS) and mild steel (MS) with single and multiple deck option as per the requirement of the application.
Our Machines are available in Standard 24 “(600 mm) to 100 “(2500 mm) models. The accessories like ball tray, ring tray etc are available as optional.
