What is shaking or vibrating screen?

AURY Shaking or vibrating screen is a mechanical device used to separate particles by size. These sieves use vibrating motion to promote separation of particles based on their size and composition. The main purpose of a vibrating screen is to efficiently sort and classify bulk materials such as minerals, aggregates or other granular materials into fractions of different sizes.

The following are the main components and features of vibrating screens:

Screen surface: The screen surface is the physical medium through which materials pass. It can be made from a variety of materials, including wire mesh, polyurethane, rubber, and more. The choice of screen surface material depends on the characteristics of the material being processed and the required screening efficiency.

Vibrating Mechanism: The vibrating screen is equipped with a mechanism that imparts vibrating motion to the screen deck. This movement is usually produced by an eccentric shaft, which rotates and causes the screen to vibrate. The vibrating motion promotes the movement of particles across the screen surface and helps separate them according to size.

Screen Plate: The screen plate is usually divided into multiple plates, each with a different mesh size or screen surface. The material is fed into the top plate, and vibration causes the particles to pass through the screen. The smaller particles pass through the openings in the screen surface, and the larger particles are retained.

Drive Unit: Vibratory motion is usually generated by a motor or exciter connected to the screen through a drive mechanism. This drive unit is responsible for generating the oscillatory movement of the screen.

Support structure: The vibrating screen is mounted on a support structure to absorb the power generated during operation. This structure ensures the stability and normal operation of the screen.

Shaking or vibrating screens come in various types, each designed for specific applications and operational requirements. Here are some common types of shaking or vibrating screens:

  1. Inclined Screens:

Description: Inclined vibrating screens have a multi-deck design with the screen surface set at an inclined angle. This design promotes the movement of material across the screen and facilitates effective screening.

Applications: Widely used in aggregate processing, mining, and mineral processing.

  1. Horizontal Screens:

Description: Horizontal vibrating screens have a horizontal deck arrangement. The material moves horizontally across the screen, allowing for efficient screening and high-capacity operations.

Applications: Commonly used in aggregate processing, sand and gravel operations, and industrial minerals processing.

  1. High-Frequency Screens:

Description: High-frequency vibrating screens operate at a higher frequency than standard vibrating screens. This design allows for finer particle separation and improved efficiency, especially in screening fine materials.

Applications: Often used in dewatering applications and fine particle screening in industries such as mineral processing.

  1. Banana Screens:

Description: Banana screens have a curved deck shape, resembling a banana. This design increases the effective screening area and improves the material retention time on the screen.

Applications: Beneficial for screening fine and sticky materials in aggregate processing and mineral processing.

  1. Linear Motion Screens:

Description: Linear motion vibrating screens have a linear vibration motion, where the material moves in a straight line on the screen deck. This design is effective for high-capacity screening.

Applications: Commonly used in heavy-duty applications such as coal processing and iron ore production.

  1. Circular Motion Screens:

Description: Circular motion vibrating screens have a circular or elliptical motion. This design provides efficient screening and is suitable for a variety of materials.

Applications: Used in aggregate processing, industrial minerals processing, and other applications where circular motion is preferred.

  1. Flip-Flop Screens:

Description: Flip-flop screens have elastic screen mats that allow for the efficient screening of difficult-to-screen materials. The mats flip and flop to prevent clogging.

Applications: Suitable for screening moist, sticky, and difficult-to-screen materials in various industries.

  1. Grizzly Screens:

Description: Grizzly screens use a set of parallel bars or rails to scalp off oversize material before it reaches the primary crusher or processing equipment.

Applications: Often used in mining and quarry operations to remove oversized rocks and debris.

Uses of Shaking or Vibrating Screens:

1.Aggregate Processing:

Use: Separation of different-sized aggregates in construction and road-building projects.

2.Mining and Mineral Processing:

Use: Classification and separation of minerals based on particle size in mining operations.


Use: Screening and grading of quarry materials to produce different-sized products.

4.Coal Handling:

Use: Sizing and classifying coal particles for further processing in coal preparation plants.


Use: Separation of recyclable materials in waste processing facilities.

6.Waste Water Treatment:

Use: Dewatering and screening of sludge and wastewater in treatment plants.

Food Processing:

Use: Separation of food products based on size or particle characteristics.

7.Chemical Processing:

Use: Screening and classifying chemical materials in various production processes.


Use: Separation of pharmaceutical products based on particle size or characteristics.

9.Ceramics and Glass Industries:

Use: Sizing and grading of raw materials in the production of ceramics and glass.

Vibrating screens are widely used in various industries such as mining, quarrying, construction and recycling to separate and classify materials according to their particle size. They are essential for efficient handling of bulk materials and are available in a variety of configurations including tilt screens, horizontal screens and multi-deck screens. The vibrating motion of screens helps convey, separate and classify particles, making these devices an integral part of many material handling and processing operations.

The selection of the appropriate type of shaking or vibrating screen depends on factors such as the type of material being processed, particle size distribution, capacity requirements, and the desired screening efficiency. Each type of screen has its advantages and is designed to excel in specific applications.
