Techniques

Chapter 1: Techniques

Vibrasieve: The Mechanism of Separation

The Vibrasieve, also known as a vibrating fine screen, utilizes the principle of mechanical vibration to separate solid particles from liquids. This technique relies on a screen deck, typically constructed from wire mesh or perforated sheet metal, mounted on a vibrating frame.

The screen deck is subjected to precise, controlled vibrations, causing the liquid to pass through the openings while retaining the solid particles. The size of the openings in the screen deck determines the size of the particles that are retained.

Key factors influencing Vibrasieve performance:

  • Frequency and Amplitude of Vibration: These factors determine the effectiveness of the separation process. Higher frequency and amplitude generally lead to better separation efficiency, but they also increase energy consumption and wear and tear on the screen deck.
  • Screen Deck Inclination: A slight inclination of the screen deck helps facilitate the movement of solids towards the discharge point.
  • Screen Deck Material and Construction: The choice of screen deck material and its construction (mesh size, thickness, etc.) directly influence the separation efficiency and durability of the system.

Variations of Vibrasieve Technology:

While the basic principle remains the same, various modifications to the vibrating mechanism and screen deck design exist to cater to specific applications. Some examples include:

  • Linear Vibrating Screens: These screens employ a linear reciprocating motion for separation.
  • Circular Vibrating Screens: These screens use a circular vibrating motion, often used for dewatering applications.
