Vibratory Screening Machine

Product description

Rotary vibration screen is an efficient and widely used screening equipment, which is mainly composed of screen box, vibration motor, vibration damping device and base. With its unique screening principle, it has the significant advantages of high screening accuracy, large processing capacity and low noise, and undertakes the important task of accurate classification and screening of various powdered and granular materials in many industries such as food, chemical, pharmaceutical, mining and so on.

Working principle
The working principle of the rotary vibration screen is: through the vibration motor to generate exciting force, so that the screen box to do high-frequency three-dimensional rotary vibration movement. The motor shaft drives the eccentric block to rotate, and the centrifugal force generated makes the screen box vibrate simultaneously in the horizontal, vertical and inclined directions. After the material enters the screen surface from the feed port, it quickly disperses under the action of this complex vibration. The fine particle material smaller than the screen size is discharged from the corresponding outlet through the screen under the action of vibration and gravity; The coarse particles larger than the screen aperture move in a circle along the screen surface and are finally discharged from the other end of the discharge port, so as to achieve the grading and screening of the material.
 
Features & Benefits

High screening accuracy: three-dimensional rotary vibration movement makes the material fully dispersed on the screen surface, can effectively avoid particle agglomeration and blocking the screen, can achieve high precision screening, for fine particles, high precision requirements of the material screening effect is significant, can meet the strict requirements of different industries for material size classification.

Large processing capacity: high-frequency vibration and large screen surface area, so that the material on the screen surface quickly move, increase the amount of processing per unit time, can adapt to the needs of large-scale production, improve production efficiency.

Wide range of application: can be replaced by different mesh screen, suitable for all kinds of powder, granular material screening, in food, chemical, pharmaceutical, mining and other industries are widely used, such as flour, milk powder, chemical raw materials, ore powder screening.

Simple structure: mainly composed of screen box, vibration motor, vibration damping device and base, the overall structure is simple, easy to install, operate and maintain, reduce the cost of equipment and maintenance difficulty.

Low noise: The use of vibration reduction device and reasonable structural design, effectively reduce the vibration transmission to the foundation and the surrounding environment, low noise during operation, improve the working environment, in line with environmental protection and occupational health requirements.
