What Is Rundown Screen?
A rundown screen (also known as a parabolic screen, gravity screen, or static rundown screen) is a type of filtration equipment used to separate solids from liquids through gravity. It is commonly used in industrial applications such as wastewater treatment, food processing, pulp and paper production, and mining.
Key Features of a Rundown Screen:
-
Static Operation: The screen has no moving parts. The separation process relies on gravity, with liquid flowing over the screen surface, while solids are captured and slide down.
-
Curved or Parabolic Shape: The screen is typically curved in a parabolic shape, allowing for the efficient flow of liquid through the openings while retaining solids.
-
Wedge Wire Design: The screen surface is made of wedge wire, which allows for precise filtration and separation. The gap between the wires determines the particle size that can pass through.
-
Low Maintenance: Since it has no moving parts, rundown screens require minimal maintenance and have a long operational lifespan.
-
Simple Operation: Liquid is fed to the top of the screen, and as it runs down the curved surface, the liquid passes through the openings, while solids are collected separately.
Applications:
- Wastewater Treatment: For separating solids from wastewater before further processing.
- Food and Beverage: In the extraction of liquids from fruits, vegetables, or other solids.
- Mining: For separating ore from process water.
- Pulp and Paper: To remove fibers from process water.
