Introduction:
The bouncing screen is designed to efficiently separate materials by size using a unique method of motion. It consists of a screen bed that vibrates vertically and horizontally, causing the material to bounce and move across the surface. This movement helps to prevent clogging and ensures high throughput and accuracy in particle separation.

Working Principle:
Material Feeding:
- The raw material is fed onto the screen at one end.
Screen Bed Movement:
- The screen bed is mounted on springs or elastic elements and is driven by a vibration mechanism.
- When activated, the screen bed performs a combination of vertical and horizontal movements.
- This causes the material to jump or bounce on the screen, facilitating its travel across the surface.
Particle Separation:
- As the material bounces, smaller particles pass through the screen mesh while larger particles continue to move along the screen surface.
- The separated products are collected at different discharge points depending on their size.
Discharge:
- The screened material is discharged from the other end of the screen or through different outlets based on size.
Key Features:
- High Efficiency:
- The bouncing action increases the probability of particles coming into contact with the screen, improving separation efficiency.
- Low Maintenance:
- Due to the simple design and the use of springs or elastic elements, maintenance requirements are relatively low.
- Versatility:
- Suitable for a wide range of materials including powders, granules, and larger solids.
- Reduced Clogging:
- The bouncing motion helps to keep the screen mesh clear, reducing the risk of clogging and ensuring consistent performance.
- Adjustable Screening Parameters:
- Users can adjust the amplitude and frequency of the screen's movement to optimize performance for specific applications.
- Energy Efficiency:
- Compared to some other types of screens, the bouncing screen may require less energy due to its efficient design.
- Easy Cleaning:
- The open design allows for easy access for cleaning and maintenance, which is particularly useful when handling materials that require frequent changes.
Bouncing screens are commonly used in industries such as food processing, pharmaceuticals, chemical production, and mineral processing, where precise and efficient particle separation is required.
