What is the classification of vibrating screen?

Vibrating Screen can be classified based on various criteria, including their motion, drive mechanism, and deck structure. Here are some common classifications of vibrating screens:

  1. Motion Type:
  • Circular Motion Screens: These screens have a circular or elliptical motion. They are effective for medium to coarse particle separation and are commonly used in applications such as mineral processing.
  • Linear Motion Screens: Linear vibrating screens operate in a straight-line motion, providing efficient screening of materials. They are suitable for high-tonnage applications and fine particle separation.
  1. Drive Mechanism:
  • Direct Drive Screens: In direct drive screens, the vibrating mechanism is directly attached to the screen frame. This configuration provides simplicity and ease of maintenance.
  • Belt-Driven Screens: Screens with a belt-driven mechanism use a belt and pulley system to generate the vibration. This configuration allows for adjustable vibration characteristics.
  1. Number of Decks:
  • Single Deck Screens: These screens have one layer of screen panels and are suitable for coarse particle separation.
  • Double Deck Screens: Double deck screens have two layers of screen panels, allowing for the separation of materials into two different size fractions.
  • Multi-Deck Screens: Screens with three or more decks provide additional levels of particle separation and classification.
  1. Screening Surface Material:
  • Woven Wire Screens: Screens with woven wire panels are commonly used in applications where wear resistance is important.
  • Polyurethane Screens: Polyurethane screen panels are known for their durability and resistance to abrasion. They are often used in applications with abrasive materials.
  • Rubber Screens: Rubber screen panels provide good wear resistance and are suitable for applications where noise reduction is important.
  1. Specialized Screens:
  • High-Frequency Screens: These screens operate at higher frequencies, enabling efficient fine particle separation and dewatering.
  • Banana Screens: Banana-shaped screens are inclined multi-deck screens with a curved profile, known for their high capacity and efficiency.
  • Trommel Screens: Trommel screens consist of a rotating cylindrical drum with perforated screens and are often used for screening bulk materials.
  1. Dewatering Screens:
  • Dewatering screens are designed to remove moisture from materials, improving the quality of the final product. They are commonly used in applications like coal washing plants.
  1. Inclined or Horizontal Screens:
  • Inclined Screens: These screens are tilted at an angle and are suitable for applications where material needs to move across the screen surface.
  • Horizontal Screens: Screens with a horizontal orientation are often used for applications requiring a straightforward material flow.

Understanding the specific classification of vibrating screens helps in selecting the most suitable equipment for a particular application. The choice depends on factors such as the type of material, particle size distribution, capacity requirements, and the desired end product specifications.
