1. Vibratory Sieve Introduction
1) Principle
The principle of Vibro Screen is transmitted in a pair of unbalancing weights, an upper weight installed on the shaft upper of a motor and the other weight on the shaft lower, which are capable of converting the motor rotation into a three-dimensional motion including horizontal, vertical and inclination vibration of screen. By controlling the phase-angels of those weights before operation, they provide several type of grain flow.

 |  |  |  |  |  |
Grains flow straightly from center to circumference. Easily screenable grains, speedy sieving of coarse grains. | Slight vortex motion. Ordinary screening | Deeper vortex. Enhance the screening effect. | The vortex is further lengthened and can be used for precision screening | The Deepest vortex to achieve the highest and mos teffective screening material of pulverlized grains, high condensasion or high moisture | Grains concentrated towards center. Prevent large material from popping up |

2. Vibrating Sieve Attachable functions
1) Reverse type
a) Introduction
Reverse revolution during screening aims at perfect screening
The materials in the machine are screened, usually moving clockwise toward the discharge opening, The reverse function switches the material movement between screening(counter-clockwise) and discharging (clockwise) the materials, and repeats the reversals to realize nearly perfect screening /discharge with efficiency exceeding 95%.
This can meet the powder industry's demand for finer particles.
CLASSIFICATION/DIACHARGE AT MORE THAN 95% EFFICIENCY

2) ULTRASONIC type
The Choice for fine particle separation. The ultrasonic anti-blinding action could increase throughtput by 50-100% compared to non-ultrasonic systems, in some applications, the increase is as much as 400%.
he Ultrasonic system enables separators to perform fine mesh screening (60-635mesh) on applications previously thought impossible. The system enhances screening by creating a low –amplitude, (4-6um) high frequency (36Khz) secondary vibration on screen surfaces, improving performance of fine mesh screening of both light and heavy density powders, and even particles carrying an electrostatic charge.
