Bounce screens are specialized screening machines that use a unique mechanism for separating materials based on size. Unlike traditional vibrating screens, which rely primarily on vibration to sort particles, bounce screens incorporate a bouncing action that helps to loosen and separate the material being screened. This makes them particularly effective at handling sticky or damp materials that might clog other types of screens.
The design typically includes a screen surface that is inclined and oscillates vertically. As the material moves down the incline, it encounters the screen surface, causing the smaller particles to pass through while larger particles are discharged over the top. The bouncing action helps to prevent blockages and ensures efficient separation.
Bounce screens operate based on the principle of utilizing the different physical properties of the waste materials being processed. The key components include a drive motor, active and passive shafts, eccentric wheels, and a screen bed that is designed to mimic a bouncing motion. The main mechanism of action is as follows:
Drive Mechanism:
Screen Bed Movement:
Material Separation:
Sieve-Down Materials: Smaller particles like sand, soil, residue, and organic matter fall through the screen.
Bounce screens are widely used in various waste management scenarios:
Construction Waste:
Renovation Waste:
Municipal Solid Waste (MSW):
Recycling Plants:
Composting Facilities:
