Banana vibrating screens and linear vibrating screens are both types of vibratory screens used for separating and classifying materials, but they differ significantly in design, operation, and application.
Design and Structure
Shape: Named for their distinctive shape, banana screens have multiple decks with different angles of inclination, resembling the shape of a banana.
Deck Configuration: Typically, the screen decks start at a steeper angle and then flatten out toward the discharge end. This design allows for a higher feed rate and greater efficiency in handling large volumes of material.
Operation
Vibration Mechanism: Uses a combination of circular and linear vibrations to move materials along the screen surface.
Flow Characteristics: The changing angle of inclination helps maintain a higher material flow rate, allowing for better separation efficiency and higher throughput.
Screening Efficiency: Higher due to the variable deck angles, which optimize the screening process for different material sizes.
Applications
Large-Scale Operations: Ideal for high-capacity screening applications in industries such as mining, mineral processing, and coal preparation.
Diverse Material Handling: Suitable for screening a wide range of materials from fine particles to large rocks.
Design and Structure
Shape: Linear screens have a more straightforward rectangular or square design.
Deck Configuration: Generally consists of a single or multiple flat, horizontal decks.
Operation
Vibration Mechanism: Operates using linear vibrations generated by one or more vibrating motors. These vibrations move materials along a straight path on the screen surface.
Flow Characteristics: Materials move in a straight line from the feed end to the discharge end, which is ideal for applications requiring precise separation of materials.
Screening Efficiency: While effective, the efficiency may not match that of banana screens in handling large volumes of material quickly.
